    BLACKBURNE-RIGSBY, Chief Judge: Following a joint jury trial, nineteen-
    year-old twins appellants Christopher and Christina Lucas were found guilty of
    aggravated assault while armed with a “[b]ias-related” penalty enhancement on the
    basis of sexual orientation in connection with an assault on victim Jaye Davis. 1
    Christopher Lucas was also found guilty of simple assault on victim Ashley
    Coleman. 2 They appeal their convictions.
    Appellants raise several issues on appeal, two of which – the trial court’s
    response to a jury question and the sufficiency of the evidence – require this court

    to interpret the Bias-Related Crime Act of 1989, D.C. Code § 22-3701(1) (the “Bias-
    Related Crime Act”). The Act states, in relevant part, that a “‘[b]ias-related crime’
    means a designated act that demonstrates an accused’s prejudice based on the actual
    or perceived . . . sexual orientation . . . of a victim of the” crime.
    Id. We are tasked
    with determining the role prejudice must play in motivating a crime before triggering
    the enhanced criminal penalties the Bias-Related Crime Act evokes.
    Appellants contend that a proper reading of the statute, based on its plain
    language and applicable constitutional principles, requires but-for causation,
    meaning the jury must determine whether appellants would not have attacked Jaye
    Davis “but for” their prejudice against him based on his sexual orientation. See
    Burrage v. United States, 
    571 U.S. 204
    , 210-211 (2014). Analyzed pursuant to this
    standard, they contend, the evidence was insufficient for the jury to apply the bias
    enhancement because the evidence shows various motivations for appellants’ attack
    on Jaye Davis, but does not show that they attacked him because of their prejudice
    against him based on his sexual orientation. The government maintains that any
    argument related to the correct interpretation of § 22-3701(1) of the statute is waived
    because appellants failed to request a jury instruction requiring but-for causation at
    any point during trial. Assuming the issue is appropriately preserved, however, the
    government argues that a lesser standard should apply. Further, the government
    4
    contends, even if but-for causation is required, the trial court appropriately
    communicated that standard to the jury.          The government urges us to affirm
    appellants’ convictions because, it argues, there was sufficient evidence to support
    the jury’s findings under either standard.
    We hold that the Bias-Related Crime Act requires but-for causation, such that
    the government must prove that the appellants assaulted Jaye Davis because of their
    prejudice against him based on his sexual orientation. The trial court appropriately
    instructed the jury on how to apply the Bias-Related Crime Act. Moreover, in
    applying but-for causation, we conclude that the evidence was sufficient for the jury
    to find that appellants would not have attacked Jaye Davis absent their prejudice
    against him based on his sexual orientation. Appellants’ arguments as to the
    causation standard under the Bias-Related Crime Act, however, do not affect their
    underlying simple and aggravated assault convictions.         Finding no abuse of
    discretion on appellants’ remaining challenges to the evidence supporting those
    assault convictions, discussed further below, we affirm.
    I.     Factual and Procedural Background
    5
    During the evening of October 18 and early morning hours of October 19,
    2013, appellants assaulted Jaye Davis after a family gathering hosted at the home of
    his uncle, Leo Davis, in Northwest Washington, D.C. 3 That evening, Jaye arrived
    at Leo’s home between 8:30 and 9:00 p.m. From the moment he arrived at the
    gathering until he left, Jaye was the subject of homophobic taunts, including “gay
    this and gay that” comments in tones of “anger and disgust” and being called
    “f[*]ggot a[*]s mother f[*]cker.”     When Jaye arrived at the party, appellants
    Christopher and Christina – who were at the gathering – stared, pointed at Jaye, and
    said, “Who is this gay motherf[*]cker?” Appellants both gave Jaye a disgusted look.
    Jaye openly identifies as gay, and his cousin Ashley Coleman, also present at Leo’s
    house, testified that he “walks . . . girly,” “talks girly,” and “acts” in a way that
    exhibits effeminate stereotypes of gay men.
    At one point in the evening, Jaye became involved in an argument with some
    individuals, including appellants. 4 Ashley could not remember with whom Jaye was
    arguing, but testified that Jaye “was going back and forth. He was cursing . . . . he
    was being loud, but he was saying things in defense of himself . . . . It was an
    3
    The individuals in this opinion will be referred to by their first names
    because many share last names.
    4
    The argument allegedly arose out of an altercation between Ashley and
    Annie Elder, Christopher’s girlfriend.
    6
    argument of words. It was a fight with words.” The situation escalated, causing
    another individual, Andre Holland, to intervene on Christina’s behalf. Holland
    testified that Jaye and Leo were trying to push Christina, prompting Holland to fight
    back against both. The police arrived before the argument got out of hand and
    instructed the crowd to disperse.
    Jaye, his cousin Ashley, and his mother Alicia Coleman left the party at
    around 12:20 a.m. and walked to the corner of Sherman Avenue and Harvard Street
    Northwest to find a cab; at that intersection, they noticed that a large group had
    followed them. Appellants led the group, saying, “[T]here go that f[*]ggot mother
    f[*]cker right there.”   Ashley and Alicia testified that the group, numbering
    approximately ten people and including appellants Christopher and Christina,
    attacked Jaye, as well as Ashley and Alicia. During the fight, Christopher hit Ashley
    in the head and knocked her to the ground. At one point, Jaye was grabbed by his
    throat, pulled onto the ground, and dragged along the sidewalk. Both Christopher
    and Christina targeted Jaye and stomped on his face, all while yelling remarks like
    “f[*]ggot mother[*]cker.” Christina then took a razor-like object from her pocket,
    kneeled next to Jaye, and cut open his face along the left eye. Jaye was left bloodied
    and unconscious, and the group – including appellants – ran off. Police officers
    7
    patrolling the area heard loud screaming, quickly arrived at the scene, and observed
    Jaye “bleeding in the face,” in pain, and being cradled in Alicia’s arms.
    Jaye testified that he lost consciousness during the assault and did not regain
    consciousness until later in an ambulance. Upon arrival at the hospital, Jaye rated
    his pain as “severe” and testified that his pain was “like 100” on a scale of one to
    ten. Dr. Ashley Humphries, the trauma surgeon who treated Jaye, testified that he
    had “several obvious injuries to his face” upon his arrival. Jaye received stitches for
    two face lacerations next to and beneath his left eye, one of which was “fairly jagged
    in appearance.” A CT scan and X-rays revealed a sinus fracture and a cheekbone
    fracture. Jaye also suffered swelling to his wrist, lips, and eyes, and was left with an
    “ugly” black scar under his eye. Jaye could not recall who among the group attacked
    him first, but remembered hearing “[t]he same words” during the attack that he had
    heard when he first arrived at the party: “[t]his f[*]ggot a[*]s mother f[*]cker,
    f[*]ggot a[*]s mother f[*]cker.”
    At trial, appellants presented evidence that they were not present at the time
    of the assault. The jury did not credit their testimony, convicting them of aggravated
    assault while armed. As to the bias enhancement, appellants argued that any assault
    on Jaye occurred because of other motivations, such as the earlier altercation at Leo’s
    8
    house, rather than Jaye’s sexual orientation. The jury returned separate verdicts
    finding that each appellant committed the crime because of Jaye’s actual or
    perceived sexual orientation. Christopher was also convicted of simple assault on
    Ashley.
    On appeal, appellants raise legal arguments involving the jury instruction
    under the Bias-Related Crime Act and a related jury note, arguing that the trial court
    failed to instruct the jury that the penalty enhancement requires but-for causation.
    Under a but-for causation standard, appellants argue that the evidence was
    insufficient to find that they attacked Jaye because of prejudice against him based
    on his sexual orientation. Appellants then raise three challenges related to the trial
    court’s decisions to (1) limit cross-examination related to the defense’s theory of the
    case; (2) permit Jaye’s mother to testify about his condition after he was attacked,
    which, appellants argue, elicited an improper emotional response from the jury; and
    (3) excuse Jaye after he testified in the government’s case-in-chief.
    II.    Causation and the Bias-Related Crime Act
    In deciding this appeal, we must first determine the causation standard under
    the bias enhancement statute. We review issues of statutory interpretation de novo.
    9
    Aboye v. United States, 
    121 A.3d 1245
    , 1249 (D.C. 2015). Questions of statutory
    interpretation begin with the plain language of the statute, and we construe words
    according to their ordinary meaning. See Clyburn v. United States, 
    48 A.3d 147
    ,
    151 (D.C. 2012). The words of a statute must be read “in light of the statute taken
    as a whole” and “are to be given a sensible construction, [] one that would not work
    an obvious injustice.”
    Id. (quoting Columbia Plaza
    Tenants’ Ass’n v. Columbia
    Plaza Ltd. P’ship, 
    869 A.2d 329
    , 332 (D.C. 2005)). When appropriate, we also
    consult a statute’s legislative history.
    Id. A. Statutory Text
    and Our Jurisprudence
    The Bias-Related Crime Act provides enhanced criminal penalties for persons
    who commit bias-related crimes, with the opportunity for appropriate civil relief for
    their victims. See D.C. Law 8-121, 37 DCR 27 (May 8, 1990). Section 22-3701(1)
    of the D.C. Code defines a “[b]ias-related crime” as
    a designated act that demonstrates an accused’s prejudice
    based on the actual or perceived race, color, religion,
    national origin, sex, age, marital status, personal
    appearance, sexual orientation, gender identity or
    expression, family responsibility, homelessness, physical
    disability, matriculation, or political affiliation of a victim
    of the subject designated act.
    10
    See also D.C. Code § 22-3704(a) (2012 Repl.) (providing civil relief to those injured
    “as a result of an intentional act that demonstrates an accused’s prejudice based on”
    one of the same protected characteristics). Simply put, the statute authorizes a
    penalty enhancement if an individual commits a criminal act that “demonstrates . . .
    prejudice” based on a victim’s protected characteristic.
    Id. § 22-3701(1). 5
    This court has only had one other occasion to review the statutory definition
    of “bias-related crime,” and only did so on limited, plain error review. In Shepherd
    v. United States, 
    905 A.2d 260
    (D.C. 2006), we recognized that the statutory
    definition of “bias-related crime” – that a criminal act “demonstrates an accused’s
    prejudice based on” a protected characteristic – might, if applied literally, punish
    “only the fact of being prejudiced, without the constitutionally-required nexus
    between that prejudice and the proscribed conduct.”
    Id. at
    262 (citing R.A.V. v. City
    5
    The statute defines a “designated act” as
    a criminal act, including arson, assault, burglary, injury to
    property, kidnapping, manslaughter, murder, rape,
    robbery, theft, or unlawful entry, and attempting, aiding,
    abetting, advising, inciting, conniving, or conspiring to
    commit arson, assault, burglary, injury to property,
    kidnapping, manslaughter, murder, rape, robbery, theft, or
    unlawful entry.
    D.C. Code § 22-3701(2). In Aboye, we held that the definition of “designated act”
    in § 22-3701(2) was not limited to the crimes delineated therein, but rather included
    “any criminal act under District of Columbia 
    law.” 121 A.3d at 1249
    .
    11
    of St. Paul, 
    505 U.S. 377
    (1992)). Because the appellant in Shepherd raised the
    constitutional issue for the first time on appeal, however, we subjected his argument
    to plain error review and did not “review[] the constitutionality of the statutory
    definition of a ‘bias-related crime.’”
    Id. 262.
    We found that appellant’s conviction
    did not present this constitutional issue because the trial court “implicitly applied the
    statute as requiring a clear nexus between the bias identified in the statute and the
    assault”; therefore, it was “appellant’s assaultive conduct motivated by bias, not his
    homophobic prejudice as such, that was subject to criminal sanction.”
    Id. at
    262-63.
    
    The court in Shepherd did not attempt to identify the causation standard required by
    the Bias-Related Crime Act, but merely found no plain error in the trial court’s
    decision – basing the penalty enhancement on a finding of a nexus between the
    appellant’s bias and the assault – thereby sidestepping a constitutional issue.
    B.     Constitutional Concerns
    Understanding what causation is required for an act to “demonstrate[]
    prejudice” requires us to determine whether the Bias-Related Crime Act punishes
    only the fact of being prejudiced, a potentially impermissible infringement on an
    individual’s First Amendment right to expression, or whether it punishes conduct
    with a sufficient nexus to the prohibited prejudice. As the parties note, the District’s
    12
    Bias-Related Crime Act is different from most states’ hate-crime laws, in that the
    “majority of [state] statutes define a hate crime as one in which the actor committed
    the offense ‘because of,’ ‘by reason of,’ or ‘on account of” another person’s race or
    other protected status.” Zachary J. Wolfe, Hate Crimes Law § 3:8 (June 2019)
    (surveying statutes). Instead, the “demonstrates . . . prejudice” language of the
    District of Columbia’s Act does not expressly require a causal connection between
    bias and the criminal act and would appear to punish “the fact of being prejudiced,”
    
    Shepherd, 905 A.2d at 262-63
    , thus raising constitutional concerns. See 
    R.A.V., 505 U.S. at 391
    (finding hate crime statute that prohibits speakers from expressing views
    on disfavored subjects places an unconstitutional limit on freedom of expression).
    In constructing a constitutionally coherent understanding of the Bias-Related
    Crime Act, we take guidance from Wisconsin v. Mitchell, 
    508 U.S. 476
    (1993), in
    which the Supreme Court upheld the constitutionality of a Wisconsin hate crime
    penalty enhancement statute that prohibited crimes where the perpetrator
    “intentionally selects the person . . . because of” the person’s protected characteristic.
    Id. at
    479-80. Because the statute punished bias-motivated criminal conduct (rather
    than explicitly prohibiting expression, i.e., speech or messages), the Court concluded
    that “the statute in th[e] case [was] aimed at conduct unprotected by the First
    Amendment.”
    Id. at
    487. 
    Guided by this analysis, we interpret the Bias-Related
    13
    Crime Act in a way that only punishes analogous conduct, i.e., that which is not
    protected by the First Amendment.
    We also look to State v. Stalder, 
    630 So. 2d 1072
    (Fla. 1994), in which the
    Florida Supreme Court reviewed the constitutionality of Florida’s hate crime statute,
    which is one of the only other state statutes with language similar to ours. The
    Florida statute, entitled “Evidencing prejudice while committing offense,” provides
    enhanced penalties if commission of a crime “evidences prejudice based on” the
    victim’s protected characteristic. Fla. Stat. § 775.085 (2016). The court accorded
    “plain meaning to the statute’s text and title,” finding that it “punishes all who
    ‘evidence,’ or demonstrate, prejudice in the commission of a crime.” 
    Stalder, 630 So. 2d at 1074
    .     This plain meaning, the court recognized, “proscribes bias-
    evidencing crimes,” which “embrac[es] two broad classes of offenses”: first,
    “offenses committed because of prejudice,” and second, “offenses committed for
    some reason other than prejudice but that nevertheless show bias in their
    commission.” 6
    Id. at
    1076. The court reasoned that the statute could not be read to
    apply to the second class because the expression of bias “is related to the underlying
    6
    The court offered the following example to demonstrate this second class of
    offense: “A beats B because of jealousy, but in the course of the battery calls B a
    racially derogatory term.” 
    Stalder, 630 So. 2d at 1076
    . The fact that the racially
    derogatory term intersects with the assault is “mere temporal coincidence.”
    Id. 14
    crime in only the most tangential way”: they “share the same temporal framework,
    nothing more.”
    Id. As such, the
    proscribed conduct is “pure expression” and,
    pursuant to the principles articulated by the Supreme Court in R.A.V., “cannot be
    selectively banned.”
    Id. Thus, the court
    read the Florida statute as “embracing only
    bias-motivated crimes,” i.e., the first class of offenses, in which the “targeted
    activity—the selection of the victim—is an integral part of the underlying crime”
    and therefore not protected speech at all.
    Id. The court read
    the Florida statute
    narrowly, consistent with the statutory language and legislative intent, to save it from
    unconstitutionality, holding that a bias-motivated crime is “any crime wherein the
    perpetrator intentionally selects the victim because of the victim’s” protected
    characteristic.
    Id. at
    1077.
    
    “[W]e apply the canon of constitutional avoidance, ‘an interpretive tool,
    counseling that ambiguous statutory language be construed to avoid serious
    constitutional doubts.’” Competitive Enter. Inst. v. Mann, 
    150 A.3d 1213
    , 1236
    (D.C. 2016) (quoting FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 516
    (2009)). Mitchell and Stalder lead us to conclude that the Bias-Related Crime Act
    is constitutional to the extent that it provides an enhanced penalty for bias-motivated
    crimes, that is, a crime that an individual perpetrates against a victim because of
    prejudice based on the victim’s protected characteristic. While both courts endorsed
    15
    an “intentional selection” standard (Mitchell by statute and Stalder by
    interpretation 7), neither defined the constitutional floor of criminal liability pursuant
    to a hate crime statute under that standard. 8 Instead, both recognize that the
    constitutionality of the hate crime statute is premised on punishing conduct causally
    linked to the individual’s bias against a victim because of statutorily defined
    protected characteristics.
    C.     Legislative History
    Concluding that the Bias-Related Crime Act only reaches bias-motivated
    crimes, we must determine its causation standard. Because of the lack of clarity in
    7
    After Stalder, a Florida intermediate court analyzed the causation standard
    applicable to Florida’s “evidencing prejudice” statute – which the court in Stalder
    interpreted as requiring that the “perpetrator intentionally selects the victim because
    of the victim’s” protected 
    characteristic, 630 So. 2d at 1077
    – and held that “[t]he
    essence of criminality under section 775.085 is that prejudice be a significant factor
    in bringing about the commission of the underlying crime, i.e., but for the racial
    enmity, the underlying crime would not have occurred.” State v. Hart, 
    677 So. 2d 385
    , 387 (Fla. Dist. Ct. App. 1996). The Florida Supreme Court has not since
    weighed in on the statute’s causation standard.
    8
    For example, at least one court has held that an “intentional selection”
    standard under the sentencing enhancement of the federal hate crime statute is met
    by a “substantial motivating factor” standard, see United States v. Smith, 365 F.
    App’x 781, 788 (9th Cir. 2010), though it remains unclear whether an “intentional
    selection” standard requires anything more than but-for causation. See supra n.7.
    16
    the statutory language of “demonstrates . . . prejudice,” we turn to legislative history
    to evaluate whether the Council of the District of Columbia (the “Council”)
    expressed its intent on this question. 
    Clyburn, 48 A.3d at 151
    . The Judiciary
    Committee of the Council, in a report issued prior to enactment, stated that the need
    for the Bias-Related Crime Act arose from “an alarming increase in crimes
    motivated by bigotry and prejudice in the District.” Report to the Council on Bill 8-
    168 from the Committee on the Judiciary, at 2 (Oct. 18, 1989). 9 In support of the
    bill, Inspector David W. Bostrom of the D.C. Metropolitan Police Department
    (MPD), testifying on behalf of the executive branch, stated that “[i]t is our
    understanding that the intent of [the criminal provisions] of this Bill is to enhance
    the criminal penalties for a crime when the crime is committed because of prejudice
    based upon the victim’s” protected characteristic.
    Id. at
    Attachment III, p. 1
    (emphasis added). Inspector Bostrom advocated against then-proposed language
    that defined a “[b]ias-related crime” as a “designated criminal act ‘that demonstrates
    9
    We note with concern that the number of hate crimes in the District has only
    risen since the passage of the Bias-Related Crime Act (which we acknowledge may
    be a result of increased reporting). As reported by the Metropolitan Police
    Department (MPD), the number of bias-related crimes reached a high of 205
    offenses in 2018 (dropping slightly lower to 203 in 2019) from a low of 38 in 2008.
    See MPD, Bias-Related Crimes (Hate Crimes Data) (last visited June 23, 2020),

    in whole or in part, prejudice based upon’” a protected characteristic.
    Id. (emphasis added). A
    later version of the bill deleted the “in whole or in part” language, but
    defined “[b]ias-related crime” as “a separate element of a designated act that is
    proven and found to be based primarily upon” the protected characteristic.
    Id. at
    Attachment II, pp. 1-2 (emphasis added).         The Council ultimately enacted a
    definition of “bias-related crime” that excluded both “in whole or in part” and
    “primarily,” passing the current language of “demonstrates . . . prejudice.” See D.C.
    Law 8-121, § 2; D.C. Code § 22-3701(1). The legislative history is silent as to this
    final change, thus providing little insight as to the Council’s intent regarding
    causation and merely evincing the Council’s intent to eschew both “in whole or in
    part” and “primarily” as causation standards. See also Bostock v. Clayton Cty., Ga.,
    No. 17-1618, --- S. Ct. ---, 
    2020 WL 3146686
    , at *5 (June 15, 2020) (noting that
    legislative intent when using words such as “solely” and “primarily” is meant to
    indicate that a factor be the sole or “main cause”).
    D.     But-For Causation
    Against this backdrop, the government argues that the most natural reading of
    the statute is that an act demonstrates prejudice if the accused’s prejudice is a
    “contributing cause” of the crime or a motivating factor. Appellants, on the other
    18
    hand, argue that but-for causation is required. Both parties rely on the Supreme
    Court’s discussion of the causation standard for criminal liability in Burrage v.
    United States, 
    571 U.S. 204
    (2003), asserting that Burrage supports their respective
    positions.
    In Burrage, the Supreme Court analyzed the causation standard of the
    mandatory-minimum sentencing provision of the Controlled Substances Act, which
    imposes a twenty-year mandatory minimum sentence on any defendant who
    unlawfully distributes a controlled substance when “death or serious bodily injury
    results from the use of such substance.” 
    Burrage, 571 U.S. at 206
    (quoting 21 U.S.C.
    § 841(a)(1), (b)(1)(A)-(C) (2012 ed.)). The Court held that “results from,” when
    given its ordinary meaning, “requires proof that the harm would not have occurred
    in the absence of—that is, but for—the defendant’s conduct.”
    Id. at
    211 
    (internal
    quotation marks and citation omitted). Even if there are multiple contributing
    factors, one factor can be a but-for cause “so long as the other factors alone would
    not have [caused the particular result] – if so to speak, it was the straw that broke the
    camel’s back.”
    Id. The Court noted
    that “results from” as employed in §
    841(b)(1)(C) is similar in meaning to other causation language such as “based on”
    and “because of,” all of which require but-for causation.
    Id. 212-13.
    The “but-for
    requirement is a part of the common understanding of cause.”
    Id. at
    211
    ; 
    see also
    19
    Bostock, 
    2020 WL 3146686
    , at *4 (describing but-for causation as a “simple” and
    “traditional” standard).
    While the Court in Burrage concluded that the Controlled Substances Act
    required but-for causation, it recognized and discussed the implications of such a
    standard for purposes of criminal liability. The Court noted that but-for causation is
    reflected in the Model Penal Code’s “traditional understanding” of causal
    relationship: that “[c]onduct is the cause of a result [when] it is an antecedent but
    for which the result in question would not have occurred.” 
    Burrage, 571 U.S. at 211
    (quoting Model Penal Code § 2.03(1)(a) (Am. Law Inst. 1985)). This formulation,
    the Court noted, represents “the minimum requirement for a finding of causation
    when a crime is defined in terms of conduct causing a particular result.”
    Id. (quoting Explanatory Note
    to Model Penal Code § 2.03(1)). In comparison, the Court
    recognized that a “substantial” or “contributing” factor test – as the government
    proposed in Burrage (and also proposes here) – fails to clarify “how important or
    how substantial a cause must be” (“50 percent more likely? Fifteen percent? Five?
    Who knows”) and therefore would inject “[u]ncertainty” that “cannot be squared
    with the beyond-a-reasonable-doubt standard applicable in criminal 
    trials.” 571 U.S. at 218
    .    Alternatively, the Court was unwilling to adopt the government’s
    “permissive” standard given the rule of lenity.
    Id. at
    216.
    20
    
    Recently in Fleming v. United States, this court accepted the analytical
    framework laid out in Burrage and held that a conviction under the District’s second-
    degree murder statute – making it a crime to “kill[] another,” i.e., cause death –
    requires but-for causation. See 
    224 A.3d 213
    , 217, 219-21 (D.C. 2020) (en banc).
    Thus, “a defendant cannot be held to have personally caused a death unless an action
    by the defendant is a but-for cause of the death, i.e., unless it is true that in the
    absence of the defendant’s action the death would not have occurred.”
    Id. In describing but-for
    causation, this court noted that it requires the government to
    “prove that, if one subtracted the defendant’s actions from the chain of events, the
    decedent would not have been killed.”
    Id. at
    221. 
    The Fleming court endorsed the
    following language as properly instructing a jury on but-for causation: “the
    government must prove that the decedent’s death occurred as a result of an action
    by the defendant. In other words, the government must prove that in the absence of
    an action by the defendant the decedent’s death would not have occurred.”
    Id. at
    229.
    Courts interpreting hate crime statutes have adopted a but-for causation
    standard in order to steer clear of breaching constitutional limits (albeit within the
    context of statutes requiring that the crime occur “because of” a victim’s protected
    21
    characteristic). See, e.g., United States v. Miller, 
    767 F.3d 585
    , 592 (6th Cir. 2014)
    (interpreting federal hate crime statute using “because of” as requiring but-for
    causation, in part because any lesser standard “treads uncomfortably close to the line
    separating constitutional regulation of conduct and unconstitutional regulation of
    beliefs”); State v. Hennings, 
    791 N.W.2d 828
    , 834 (Iowa 2010) (noting that “causal
    connection between prejudice and a prohibited action . . . protects hate-crime statutes
    from constitutional challenge,” and requiring discriminatory animus to be a but-for
    cause of the offense under the Iowa statute), overruled on other grounds by State v.
    Hill, 
    878 N.W.2d 269
    (Iowa 2016); In re M.S., 
    896 P.2d 1365
    , 1377 (Cal. 1995)
    (defining “because of” to require causation in fact and affirming constitutionality of
    California hate crime statute); 
    Hart, 677 So. 2d at 387
    (holding that under Florida
    statute, prejudice must “be a significant factor in bringing about the commission of
    the underlying crime, i.e., but for the racial enmity, the underlying crime would not
    have occurred” to comport with Stalder First Amendment analysis).
    E.     The Bias-Related Crime Act Requires But-For Causation
    We are persuaded by the reasoning of Burrage that the Bias-Related Crime
    Act requires but-for causation. To find the penalty enhancement applicable to an
    individual accused of a crime, the government must prove that the accused would
    22
    not have committed the underlying crime but-for prejudice against the victim based
    on the victim’s protected characteristic. Moreover, if there was genuine doubt
    regarding the Council’s intent, the rule of lenity would counsel us to adopt a more
    lenient interpretation in favor of criminal defendants. See Holloway v. United States,
    
    951 A.2d 59
    , 65 (D.C. 2008). In adopting a but-for causation standard, we do not
    restrict a description of such causation to the words “but for,” but instead recognize
    that such language reflects a causation standard similar in meaning to language such
    as “based on,” “because of,” and “results from.” See Campbell v. United States, 
    307 F.2d 597
    , 601 (D.C. Cir. 1962) (noting that the language “product of,” “because of,”
    “but for,” and “result of” all articulate but-for causation).       Under any such
    formulation, in this context, a jury is required to find that in the absence of an
    appellant’s bias, the crime would not have occurred.
    In arguing for a lesser standard, the government contends that but-for
    causation is misplaced when results “proceed from the contributions of many
    causes.” But-for causation, however, is entirely consistent with a situation within
    which multiple causes contribute to a specific result. At its most basic level, but-for
    causation means “where A shoots B, who is hit and dies, we can say that A actually
    caused B’s death, since but for A’s conduct B would not have died.” 
    Burrage, 571 U.S. at 211
    (quoting 1 W. LaFave, Substantive Criminal Law § 6.4(a), at 464-66 (2d
    23
    ed. 2003)). However, a factor can satisfy but-for causation when it is one of multiple
    contributing factors; it does not have to be the largest contributing factor, but can be
    one factor that combines with others to produce the result. 
    Burrage, 571 U.S. at 211
    ;
    see also Bostock, 
    2020 WL 3146686
    , at *5 (“Often, events have multiple but-for
    causes. . . . A defendant cannot avoid liability just by citing some other factor . . . .
    So long as the [prohibited factor] was one but-for cause . . ., that is enough to trigger
    the law.”). For example, if a man plagued with multiple diseases is poisoned and
    dies, the poison was a but-for cause of his death so long as, without the incremental
    effect of the poison, the man would have lived. 
    Burrage, 571 U.S. at 211
    . 10 But-for
    10
    As we recognized in Fleming, and as acknowledged by the Supreme Court,
    the “rare” exception to the existence of but-for causation is when “multiple sufficient
    causes independently, but concurrently, produce a 
    result.” 224 A.3d at 222
    (quoting
    
    Burrage, 571 U.S. at 214-15
    ). For example:
    “A stabs B, inflicting a fatal wound; while at the same
    moment X, acting independently, shoots B in the
    head . . . also inflicting [a fatal] wound; and B dies from
    the combined effects of the two wounds,” A will generally
    be liable for homicide even though his conduct was not a
    but-for cause of B’s death (since B would have died from
    X’s actions in any event).
    
    Burrage, 571 U.S. at 215
    (quoting LaFave at 468) (alternations in original).
    Although the government argues that employing a contributing cause standard
    would address such a situation, the Court in Burrage found that it would cause
    “confusion” to equate a situation in which there are “multiple independently
    sufficient causes” with a situation employing a “substantial factor” analysis.
    Id. at
    217 
    n.5. In this exceptional case, neither is truly a but-for cause because the harm
    would have occurred regardless (due to the separate, independent causes). Multiple,
    24
    causation, however, does not evaluate the weight of each factor; a factor is not a but-
    for cause merely because it contributed to a particular degree in leading to a result.
    See
    id. at 218.
    Rather, but-for causation merely determines whether a particular
    factor played a necessary role in leading to a particular result.
    The same can be said when a result is achieved and the but-for cause, though
    one of multiple causes, is the most obvious or apparent factor that caused the result.
    In the context of murder, it is “well understood” that “a defendant’s conduct that
    hastens the decedent’s death is a but-for cause of death.” 
    Fleming, 224 A.3d at 222
    .
    This is true despite the fact that everyone is mortal and that death will ultimately
    result, regardless of whether a defendant’s conduct hastens it.
    Id. Alternatively, take for
    example, a baseball game in which the visiting team’s leadoff batter hits a
    home run in the first inning. 
    Burrage, 571 U.S. at 211
    -12. If the final score is 1-0,
    the logical conclusion was that the victory was achieved because of the home run.
    Id. at
    212. Naturally, we can say that the victory was a consequence of the home
    run if the victory would not have occurred absent the home run.
    Id. Importantly, Burrage states
    that “[i]t is beside the point that the victory also resulted from a host
    independent causes represent a narrow carve-out from but-for causation, though we
    need not address such a possible exception because the government has not argued
    that the present case calls for it.
    25
    of other necessary causes,” including teamwork, skillful coaching, or favorable
    weather.
    Id. 11
    On the other hand, had the visiting team won 5-2, it cannot
    necessarily be said that the victory was owed to that single home run, mostly because
    it did not affect the outcome of the game but rather “merely played a nonessential
    contributing role in producing the event.”
    Id. Thus, to be
    considered a but-for cause of a result, the cause must be necessary
    to the result – meaning the result would not have been achieved without the cause.
    It does not matter if there were several other important causes; we must look at the
    effect the one particular cause had on the result and assess whether it may have been
    the “straw that broke the camel’s back,”
    id. at 211-12,
    or the tipping point leading to
    11
    We also find the jury instruction’s formulation of but-for causation to be
    similar to the Supreme Court’s recent discussion of that standard as applied to Title
    VII:
    [A] straightforward rule emerges: An employer violates
    Title VII when it intentionally fires an individual
    employee based in part on sex. It doesn’t matter if other
    factors besides the plaintiff’s sex contributed to the
    decision. . . . If the employer intentionally relies in part on
    an individual employee’s sex when deciding to discharge
    the employee . . . a statutory violation has occurred.
    Bostock, No. 17-1618, 
    2020 WL 3146686
    , at *6.
    26
    an outcome. By these analogies, we do not imply that a but-for cause be the last one,
    but only recognize that it must be a necessary cause – when combined with all other,
    potential causes – leading to the relevant result. We also acknowledge that but-for
    causation is not an onerous standard; it is, in fact, the minimum causation required.
    See
    id. at 211;
    see also Crews v. United States, 
    369 A.2d 1063
    , 1067 & n.3 (D.C.
    1977) (noting the “less rigorous causal analysis of the ‘but for’ test”).
    In sum, we hold that § 22-3701(1) requires that a defendant’s bias against a
    victim due to the victim’s protected characteristic must be a but-for cause of the
    defendant’s underlying criminal act. Bias need not be the sole cause, or even the
    primary cause. And it may interact with several other causes in causing the end
    result. For purposes of the Bias-Related Crime Act, however, bias against the
    victim’s protected characteristic must be a but-for cause for a factfinder to find that
    the accused committed the underlying crime.
    III.   Standard of Review
    Having found that the Bias-Related Crime Act requires but-for causation, we
    are now equipped to turn to the issues raised by appellants related to the penalty
    enhancement.
    27
    A.     Jury Instructions
    The accuracy of a jury instruction is a legal question that this court reviews de
    novo. See Wash. Inv. Partners of Del. LLC v. Sec. House, K.S.C.C., 
    28 A.3d 566
    ,
    577 (D.C. 2011). When analyzing jury instructions, the “central question for this
    court is whether the instruction is an adequate statement of the law, and whether it
    is supported by evidence in the case.” Koonce v. District of Columbia, 
    111 A.3d 1009
    , 1022 (D.C. 2015) (brackets and citation omitted). Here, we must assess
    whether the form jury instructions provided by the trial court, taken from the
    Criminal Jury Instructions for the District of Columbia, commonly referred to as the
    “Red Book,” were an accurate statement of the law. 12
    B.     Response to the Jury Note
    12
    While not the law, the Red Book jury instructions are “technically
    unofficial” form jury instructions that are “regularly updated and widely used” in the
    District of Columbia. Cousart v. United States, 
    144 A.3d 27
    , 30 n.7 (D.C. 2016).
    “The instructions and accompanying extensive comments are prepared by a
    committee consisting of volunteer judges and experienced practitioners under the
    overall supervision of a law professor.”
    Id. 28
    While we review the trial court’s decision on what, if any, response to give to
    a jury’s question for abuse of discretion; the accuracy of the instruction itself is a
    legal question that we review de novo. See 
    Fleming, 224 A.3d at 219
    ; Brown v.
    United States, 
    139 A.3d 870
    , 875 (D.C. 2016); Gray v. United States, 
    79 A.3d 326
    ,
    337 (D.C. 2013). “[T]he trial court must give the jury an accurate and fair statement
    of the law.” Pannu v. Jacobson, 
    909 A.2d 178
    , 198 (D.C. 2006). Moreover, the
    trial court should clear away the jury’s specific difficulties “with concrete accuracy.”
    
    Gray, 79 A.3d at 337
    . The jury’s confusion as to an issue requires that the trial court
    convey “an appropriate and effective response.”
    Id. C.
        Sufficiency of the Evidence
    When reviewing challenges to the sufficiency of the evidence, we “view the
    evidence in the light most favorable to the government, giving full play to the right
    of the fact-finder to determine credibility, weigh the evidence, and draw justifiable
    inferences of fact, and making no distinction between direct and circumstantial
    evidence.” Cherry v. District of Columbia, 
    164 A.3d 922
    , 929 (D.C. 2017) (citation
    omitted). We will affirm if, after reviewing the evidence in the light most favorable
    to the government, “any rational fact-finder could have found the elements of the
    29
    crime beyond a reasonable doubt.” Hernandez v. United States, 
    129 A.3d 914
    , 918
    (D.C. 2016).
    IV.    Analysis
    We conclude that the trial court’s instruction to the jury was a correct
    statement of the law, that the trial court did not abuse its discretion in reiterating that
    instruction in response to the jury note, and that the evidence was sufficient to
    support the jury’s verdict.
    A.      The Jury Instruction Adequately Reflected the Requisite
    Causation
    The trial court read to the jury the following excerpt from the Red Book
    instruction, using the names of appellants:
    The elements of the offense of bias-related crime, each of
    which the government must prove beyond a reasonable
    doubt, are that Christopher [and Christina] Lucas
    committed a criminal act against another person – in this
    case the lead charge is aggravated assault while armed –
    and he committed the crime of aggravated assault while
    armed because of prejudice based on the actual or
    perceived sexual orientation of the other person. . . .
    If you are not convinced the government has proven
    beyond a reasonable doubt the elements of a bias related
    30
    crime as that offense has been defined, you must find the
    defendant not guilty of this offense. In making your
    determination, it does not matter if Christopher [and
    Christina] Lucas had additional motives for doing what he
    did, such as personal anger or revenge.
    See Criminal Jury Instructions for the District of Columbia, No. 8.104 (5th ed. 2018)
    (emphasis added). The comment to the instruction only states that it is “based upon
    D.C. Official Code § 22-3701 (2001),” which “prohibits a designated act that
    demonstrates prejudice.”
    Id. Through the Red
    Book instruction, the trial court adequately conveyed but-
    for causation to the jury. The first paragraph of the jury instruction explains that the
    jury must find that appellants assaulted Jaye “because of” prejudice based on Jaye’s
    sexual orientation. As the Supreme Court has noted, the phrase “because of” imparts
    the requisite but-for causal standard. See 
    Burrage, 571 U.S. at 213-14
    . In describing
    terms such as “based on” and “by reason of,” the Court recognized that such
    language “in common talk . . . indicates a but-for relationship” and that the “but-for
    requirement is a part of the common understanding of cause.”
    Id. at
    211
    , 213. In
    Fleming, this court endorsed a jury instruction that used “as a result of” to describe
    31
    but-for 
    causation. 224 A.3d at 229
    . 13         Recognizing this common-sense
    understanding, we believe it is accurate to understand “because of” as articulating
    but-for causation. 14 We do not read the jury instruction as applying any lesser
    standard.
    13
    Cf. E.E.O.C. v. New Breed Logistics, 
    783 F.3d 1057
    , 1076 (6th Cir. 2015)
    (affirming jury instruction on but-for causation in Title VII retaliation case when
    instruction stated that “the plaintiff . . . must establish that [the claimants] were
    subjected to adverse employment actions by the defendant because of their internal
    complaints . . . .” and noting that “phrase ‘because of’ denotes a but-
    for causation relationship” (alternation in original)).
    14
    The dissent is not of the opinion that “because of” can convey the nuances
    of but-for causation. Expressing concern that a lay jury may not be aware that
    “because of” has been interpreted, within the legal context, to communicate “but-
    for” causation. However, we establish no expectation that the jury know about the
    specific legal interpretation, we simply clarify that but-for causation can be
    articulated in the English language in more ways than through the explicit use of
    “but-for.”
    The dissent believes the example appellant Christina Lucas provides
    highlights that the colloquial phrase “because of” cannot adequately convey the
    complexities of but-for causation. The example provided–the friend going to the
    store because she needs milk, bread, and eggs–explicitly valuates one factor’s
    contribution in bringing the result, specifically the need for eggs is the primary
    reason the friend is going to the store. As discussed, but-for causation is not a
    discernment of degree, it requires a determination that a particular factor was
    necessary to produce the result, regardless of its percentage contribution to the result
    or weight in relation to other causal factors. See supra pp. 23-24 (citing 
    Burrage, 571 U.S. at 218
    ). The initial instruction appropriately conveyed but-for causation;
    the criminal act was committed because of bias relating to the sexual orientation of
    the victim regardless of other motivating factors.
    32
    The jury was then instructed in how to evaluate bias in light of other, potential
    causal factors. The middle of the second paragraph made the jury aware that other
    motives for appellant’s conduct do not, alone, negate the applicability of the bias
    enhancement. The instruction’s explanation that “it does not matter if [appellants]
    had additional motives for doing what [they] did” is consistent with the language
    from Burrage, which noted that “[i]t is beside the point that [an outcome] also
    resulted from a host of other necessary causes.”
    Id. at
    212. Instead, the instruction
    focused the jury on bias, asking it to determine whether appellants attacked Jaye
    “because of” prejudice based on his sexual orientation. If the evidence showed,
    beyond a reasonable doubt, that appellants attacked Jaye because of his sexual
    orientation, then the jury could apply the penalty enhancement. Indeed, appellants
    do not explain how the jury could have somehow misapplied the causal element. 15
    15
    By using the language “because of,” we conclude that the Red Book
    instruction articulated but-for causation. That the instruction could more clearly
    explicate or exemplify but-for causation, such as describing bias as a necessary
    causal factor or noting that jury must find that the resulting crime would not have
    occurred in the absence of such bias, however, does not render it an inadequate or
    improper statement of the law. See 
    Koonce, 111 A.3d at 1022
    (noting that “central
    question” is whether the “instruction is an adequate statement of the law”); cf. Arthur
    Young & Co. v. Sutherland, 
    631 A.2d 354
    , 370 (D.C. 1993) (“No magic words were
    required so long as the instruction fairly and accurately informed the jury of the
    applicable law and the requirements of proof.”).
    33
    B.     The Trial Court’s Response to the Jury Note Adequately Cleared
    Away Any Potential Confusion
    We find that the trial court did not abuse its discretion in responding to the
    jury’s note by reiterating the above jury instruction. During deliberations, the jury
    sent the following note: “Does prejudice based on sexual orientation need to be the
    only reason a crime was committed? Does prejudice based on sexual orientation
    need to be the primary reason a crime was committed?” After discussing the
    questions with counsel for both sides and over the defense counsel’s objection, the
    trial court decided to reiterate the Red Book instruction to the jury:
    In your instructions on pages 19 and 27, . . . in making
    your determination it doesn’t matter if Christopher or
    Christina Lucas had additional motives for doing what
    they did, such as personal anger or revenge. Your question
    is whether or not the government has proven beyond a
    reasonable doubt that the defendants acted based upon the
    actual or perceived sexual orientation of Jaye Davis. If the
    government has proven that fact beyond a reasonable
    doubt, then you can find that there was a bias. If they have
    not proven that fact beyond a reasonable doubt, then you
    cannot find bias, notwithstanding whatever else may have
    been going on.
    34
    A few hours later, the jury returned guilty verdicts on all charges. We conclude that
    the trial court did not err in reiterating the jury instruction in response to the jury’s
    question. 16
    Appellants contend that the trial court’s response did not adequately resolve
    the jury’s confusion with respect to the required causation standard. First, we do not
    interpret the jury’s note as expressing confusion about whether to apply a different
    or lesser standard. Such an argument is only plausible when reading “because of”
    as applying a standard other than but-for causation. 17 As we explained above and as
    16
    The government contends that appellants waived their challenge by
    agreeing to the trial court’s ultimate decision to reiterate the jury instructions, and
    that, even if we were to entertain appellants’ challenge, “it would be reviewable at
    most for plain error.” We disagree that appellants’ challenge is waived or should be
    reviewed for plain error because, “consistent with the purposes of [Super. Ct. Crim.
    R. 30], the [trial] court had the opportunity to correct errors and omissions which
    otherwise might necessitate a new trial.” Preacher v. United States, 
    934 A.2d 363
    ,
    369 (D.C. 2007) (internal quotation marks omitted) (holding that appellant
    adequately preserved his request for review when “appellant’s counsel made clear
    the request for an instruction on assault before the jury resumed deliberations
    following its note specifically requesting the definition of ‘assault’”).
    17
    Appellants maintain that the jury may have applied a “motivating factor”
    or “contributing factor” test, which purportedly implies a lower standard than but-
    for causation. Jury instructions that refer to these and other standards – such as a
    substantial, contributing, or motivating factor – use language to that effect and often
    refer to the factor as one of many that may have caused the result. See, e.g., Standard
    Civil Jury Instructions for the District of Columbia, No. 5-13 (rev. ed. 2018)
    (Negligence; multiple causes) (“There may be more than one cause of harm. Several
    factors or circumstances, or the acts or omissions of two or more persons, may cause
    35
    discussed by the Court in Burrage, however, the “but-for requirement is part of the
    common understanding of cause”; in “common talk,” phrases like “‘based on’
    indicate a but-for causal 
    relationship.” 571 U.S. at 211
    , 213. There is no indication
    that the jury applied any standard other than but-for causation. At trial, defense
    counsel proposed instructing the jury using the language in Shepherd, which stated
    in dicta that the penalty enhancement can be applied when there is “a clear nexus
    between the bias identified in the statute and the 
    assault.” 905 A.2d at 262
    . As
    discussed above, our decision in Shepherd only found, under plain error review, that
    a nexus between the bias and criminal conduct was required to avoid constitutional
    issues. Instructing the jury to find “a clear nexus,” which does not convey but-for
    causation, would have misstated the law and confused the jury further. Nor is there
    any force to the argument that using additional language proposed by appellants, like
    the same harm. Each of the acts or omissions that played a substantial part in the
    harm is a cause. This is true even if one of the acts or omissions contributed more
    than another to causing the harm, so long as each act or omission played a substantial
    part in the harm.”); 
    Sutherland, 631 A.2d at 369
    (affirming the use of the following
    jury instruction for a retaliation claim under the D.C. Human Rights Act: “causation
    means something was a substantial contributing factor. The law recognizes more
    than one reason for an action. You, however, determine if protected activity, that is,
    the discrimination claim, was a substantial contributing factor in [the] decision.”);
    Furline v. Morrison, 
    953 A.2d 344
    , 350-51 (D.C. 2008) (noting that the jury
    instruction on a retaliation claim required that the “retributive motive ‘played
    a substantial part in the suspension decision, even though other factors also may
    have motivated’ the decision”).
    36
    “but-for,” would have provided the jury any further clarity than was provided by the
    use of “because of” and “based on.”
    Alternatively, and more importantly, appellants argue that the jury note
    reflected confusion about how to apply but-for causation, thus requiring the trial
    court to clear away such confusion with concrete accuracy. While we acknowledge
    that the jury’s note expressed some confusion, we must be careful to isolate the
    nature of that confusion and ensure that the trial court properly responded in kind.
    The jury’s note asked whether bias needed to be the “only” or “primary” reason for
    appellants’ conduct. These queries sought clarification from the trial court regarding
    the degree to which appellants’ prejudice needed to motivate Jaye’s assault.
    As we have discussed, but-for causation is not a discernment of degree.
    Rather, but-for causation determines whether a particular factor was necessary to
    produce a result, regardless of its percentage contribution to the result or weight in
    relation to other causal factors. See, e.g., 
    Burrage, 571 U.S. at 218
    (rejecting
    “substantial” or “contributing” factor tests because they seek to quantify the
    relationship between the relevant causal factor and the end result, thereby injecting
    uncertainty that cannot be squared with a beyond-a-reasonable-doubt standard).
    Importantly, the Council rejected “primarily” as a causation standard. Responding
    37
    to the jury’s questions concerning the degree to which bias motivated the assault
    would not have clarified any confusion about the application of but-for causation.
    The trial court’s response, therefore, sought to steer the jury back to the critical
    inquiry of but-for causation.
    Importantly, the trial court directed the jury to the initial instructions, which,
    as we explained, adequately conveyed but-for causation. The initial instruction
    informed the jury that it was required to find that appellants assaulted Jaye “because
    of” their bias, and that such determination should be made regardless of other
    potential motivating factors. The reinstruction also noted that it “doesn’t matter if
    [appellants] had additional motives,” reminding the jury that the relative weight of
    several causal factors was not determinative in assessing whether bias was a but-for
    cause. It then restated the relevant question as whether “the government has proven
    beyond a reasonable doubt that the defendants acted based upon the actual or
    perceived sexual orientation of Jaye Davis,” i.e., because of prejudice. Turning the
    jury’s focus to whether appellants acted “based upon” Jaye’s sexual orientation
    correctly clarified confusion as to whether their bias was a but-for causal factor.
    38
    Referring the jury back to the original instruction was entirely appropriate in
    this circumstance because the instructions reflected the law. 18 See Colbert v. United
    States, 
    125 A.3d 326
    , 334-35 (D.C. 2015). In Colbert, the jury sent a note to the
    judge asking for clarification as to the elements of the crimes charged.
    Id. at
    333.
    We held that the trial court’s decision to respond to the jury by “telling the jury to
    re-read the elements of each offense, paying special attention” to the language
    “already included therein,” was appropriate, particularly because the answer to the
    jury’s question was contained therein.
    Id. at
    333-34. 
    We further held that this
    approach was appropriate in that context “because there is no indication in the jury
    18
    The dissent takes the position that to clear up any jury confusion “with
    concrete accuracy,” Bollenbach v. United States, 
    326 U.S. 607
    , 612-13 (1946), the
    trial court was required to do more than restate the instruction, proposing that “but
    for” should have been explicitly included in responding to the jury note. However,
    modifying the instruction to specifically include the words “but for” is not markedly
    different than the original jury instruction because but-for causation was already
    clearly conveyed. As discussed, the phrases “because of” and “based on” are
    indicative of a but-for relationship which is commonly understood as a standard for
    assessing causation. See 
    Burrage, 571 U.S. at 211
    , 213-14.
    As mentioned, but-for causation does not entail weighing factors, but
    determines if a particular factor is necessary to produce a result. See, e.g., 
    Burrage, 571 U.S. at 218
    (rejecting “substantial” or “contributing” factor tests because they
    seek to quantify the relationship between the relevant causal factor and the end result
    but fail to clarify how important or how substantial a cause must be). Ultimately,
    substituting “because of” with “but for” would not clear up the jury’s confusion, it
    would be a recitation of the original instruction – which the trial court did, and which
    we conclude was the proper response to direct the jury back to applying but-for
    causation.
    39
    note that the jury was misinterpreting the court’s instructions or was misconstruing
    the elements of a crime.”
    Id. at
    334. 
    Colbert is analogous to this case, where the
    trial judge’s decision to answer the jury’s question – regarding the role that prejudice
    must play in appellants’ motivation – by reiterating the initial instruction was correct
    because the answer was contained therein, which instructed the jury to determine
    whether appellants assaulted Jaye because of their prejudice against his sexual
    orientation. 19   See also Waddington v. Sarausad, 
    555 U.S. 179
    , 196 (2009)
    (concluding that the trial judge’s response “directing [the jury’s] attention to the
    precise paragraph” of the jury instructions was entirely appropriate because the
    instructions were “constitutionally adequate instruction” and “answer[ed] its
    inquiry”).
    We find it compelling that the jury did not request a second clarification, and
    there is nothing in the record to suggest that the jury did not follow instructions or
    that it failed to heed the trial court’s direction. Where a jury asks no follow-up
    questions, the Supreme Court “has presumed that the jury fully understood the
    judge’s answer and appropriately applied the jury instructions.” Id.; Armstrong v.
    19
    Courts have also held that, when neither the statute nor the case law
    contains a clearer answer to the jury’s question, it may be entirely appropriate to
    repeat the jury instruction instead of attempting to give “a lengthy explanation” and
    possibly “confus[e] the jury.” Ware v. State, 
    707 S.E.2d 111
    , 113 (Ga. App. Ct.
    2011).
    40
    Toler, 
    24 U.S. 258
    , 279 (1826) (opinion of Marshall, C.J.) (“Had the jury desired
    further information, they might, and probably would, have signified their desire to
    the court. The utmost willingness was manifested to gratify them, and it may fairly
    be presumed that they had nothing further to ask.”). This is because, “[t]o presume
    otherwise would require reversal every time a jury inquires about a matter of
    constitutional significance, regardless of the judge’s answer.” Weeks v. Angelone,
    
    528 U.S. 225
    , 234 (2000).
    Thus, we conclude that it was not an abuse of discretion for the trial court to
    re-read the initial instruction, which was legally correct, to the jury to clarify any
    confusion as to the application of but-for causation. See 
    Fleming, 224 A.3d at 219
    .
    C.     There Was Sufficient Evidence for the Jury to Conclude That, But-
    For Appellants’ Bias Towards Jaye’s Sexual Orientation, They
    Would Not Have Attacked Jaye
    On appeal, appellants argue that the evidence was insufficient to apply the
    bias enhancement statute because the jury could not have concluded that but-for
    appellants’ bias against Jaye’s sexual orientation the attack would not have occurred.
    We disagree.
    41
    The evidence at trial was sufficient for a jury to find that appellants assaulted
    Jaye because of his sexual orientation, even accounting for additional motives for
    the assault. Viewed in the light most favorable to the verdict, the evidence of
    appellants’ bias toward Jaye – the volume and duration of homophobic taunts, the
    temporal proximity between the comments and the assault, and the gravity of the
    physical encounter was strong. See 
    Hernandez, 129 A.3d at 918
    (noting that we
    “view the evidence in the light most favorable to the verdict,” “defer to the fact-
    finder’s credibility determinations,” and affirm if “any rational fact-finder could
    have found the elements of the crime beyond a reasonable doubt”).
    The jury heard testimony from Jaye, Ashley, and Alicia regarding the repeated
    homophobic insults that appellants spewed at Jaye from the moment he arrived at
    the party and during their attack on him, a time frame that exceeded four hours.
    Ashley testified that, when Jaye arrived at the party, both appellants stared and
    pointed at Jaye, and Ashley heard both of them say, “Who is this gay
    motherf[*]cker?” Jaye testified that he heard “f[*]ggot a[*]s mother[*]cker” at least
    two times when he first arrived at the party. Ashley further testified that the
    appellants led the group of people who targeted Jaye prior to the attack: “They were
    in the front, and it was then, there go that f[*]ggot mother[*]cker right there; you
    thought it was over.” Jaye testified that right before appellants attacked him, he
    42
    heard chanting “‘this f[*]ggot a[*]s mother f[*]cker’ again and again” and witnessed
    a group of people approach him. Alicia’s testimony echoed that of Jaye and
    Ashley. 20 These repeated homophobic remarks, which began hours before and
    during the assault, establish far more than “mere temporal coincidence” between the
    appellants’ bias and the assault. 
    Stalder, 630 So. 2d at 1076
    . We conclude that such
    evidence was sufficient for a reasonably jury to find causation here.
    The jury needed to find that, notwithstanding any additional motives like
    anger or revenge, appellants would not have attacked Jaye in the absence of their
    bias toward him based on his sexual orientation. In Shepherd, we focused our
    sufficiency holding on the temporal proximity between the bias-evidencing
    statement and the incident, finding clear evidence of “homophobic insults” during
    the 
    assault. 905 A.2d at 263
    (holding “[t]he trial court’s finding of a nexus was
    20
    Appellants attempt to distance themselves from the hateful nature of
    “f[*]ggot” as a homophobic slur, noting testimony from Ashley that the word can be
    a generic fight word used to describe a person as “weak and sensitive” and arguing
    that the word was used “non-literally to convey disrespect and hatred, rather than
    homophobia.” We reject this contention. While words can have different meanings
    in different contexts, “f[*]ggot” can be understood to be a homophobic slur, and a
    jury reasonably could have concluded that appellants used it that way. See Cherry
    v. United States, 
    164 A.3d 922
    , 929 (D.C. 2017) (“[T]he government is not required
    to negate every possible inference of innocence.” (internal quotation marks
    omitted)). Here, the consistent use of the term “f[*]ggot” from the moment Jaye
    arrived at the party through the attack belies any argument that the word was merely
    a neutral antagonizing word to provoke a fight.
    43
    amply supported by evidence . . . that appellant accompanied his assaults on the two
    women with a verbal stream of homophobic insults”). Here, we have strong
    evidence of homophobic taunting not only during the assault, but also in the hours
    prior to the assault. Because of appellants’ numerous homophobic comments and
    the clear temporal nexus between the homophobic taunts and the attack on Jaye, the
    evidence was sufficient to establish but-for causation. See State v. Duncan, 
    878 N.W.2d 363
    , 373-74 (Neb. 2016) (concluding evidence was sufficient under hate
    crime statute requiring but-for causation, where defendant assaulted victim because
    of his belief that the victim was associated with homosexual people based on victim
    hearing defendant say “f[*]ggot” prior to the assault); 
    Hennings, 791 N.W.2d at 835
    -
    36 (finding sufficient evidence for conviction under hate crime statute requiring but-
    for causation where defendant called victim “f[*]cking n[*]ggers” and hit victim
    with his truck); People v. Davis, 
    674 N.E.2d 895
    , 895, 897 (Ill. App. Ct. 1996)
    (affirming a conviction for aggravated battery with a hate crime penalty
    enhancement requiring commission of crime “by reason of” race where evidence
    showed that defendant targeted the victim, an African-American man, when he was
    walking out of a restaurant with a white male friend and yelled “N[*]gger, I am
    going to kick your black ass,” before he beat the victim “senseless”).
    44
    The severity of the attack combined with the biased statements provides
    further evidence of appellants’ bias. See Kurd v. Republic of Turkey, 
    374 F. Supp. 3d
    37, 59 (D.D.C. 2019) (noting that, under the Bias-Related Crimes Act, “biased
    intent . . . can be inferred from circumstantial evidence, including the factual
    background . . . and each [d]efendants’ actions,” even if the plaintiffs “do not allege
    that [a d]efendant personally made” biased comments). The testimony established
    that comments concerning Jaye’s sexual orientation in tones of “anger and disgust”
    began immediately upon his arrival to Leo’s house, generally and from appellants
    specifically. Alicia testified that the group grabbed Jaye and dragged him to the
    ground while appellants “stomp[ed]” on his body and face and yelled “f[*]ggot
    mother[*]cker.”    After making these comments and stomping on Jaye’s face,
    Christina knelt down to Jaye, took a razor-like object from her pocket, and slashed
    open his cheek near his left eye. She ran away immediately after, leaving him on
    the ground and unconscious. Appellants’ conduct – following Jaye after he left the
    family gathering, dragging him to the ground, stomping on his body and face,
    slashing open his face with a razor-like object, and leaving him unconscious –
    constituted part of an attack during which hateful words were used to express animus
    toward Jaye because of his sexual orientation. The circumstantial evidence is
    sufficient to demonstrate that appellants attacked Jaye as a result of bias because of
    his sexual orientation.
    45
    The weight of the evidence of appellants’ bias toward Jaye is not mitigated by
    the fact that Christina is a gay woman.         Appellants argue that “Christina’s
    homosexuality makes it far less likely that she targeted Jaye because he shared that
    attribute.” Christina’s counsel, in fact, made this argument to the jury – “to say that
    [Christina] hated someone because they were gay would be to say that she hated
    herself.” The jury found otherwise. As appellants concede, “it is certainly possible
    for a gay woman to harbor prejudice against gay men.” Indeed, it is well known that
    people can demonstrate bias and discriminate against others who fall within the same
    protected category as they do. See, e.g., Oncale v. Sundowner Offshore Servs., Inc.,
    
    523 U.S. 75
    , 78-79 (1998) (holding that Title VII of the Civil Rights Act of 1964
    does not bar claims of employment discrimination based on sex merely because the
    plaintiff and defendant are of the same sex). In Oncale, the Supreme Court “rejected
    any conclusive presumption that an employer will not discriminate against members
    of his own” race or sex
    , id., recognizing that “‘[b]ecause
    of the many facets of human
    motivation, it would be unwise to presume as a matter of law that human beings of
    one definable group will not discriminate against other members of their
    group.’”
    Id. (quoting Castaneda v.
    Partida, 
    430 U.S. 482
    , 499 (1977)). For the
    same reasons here, it is entirely plausible for a person to commit a bias-related crime
    46
    against another person sharing the same protected characteristic because of that
    characteristic.
    V.     Appellants’ Remaining Claims
    Finally, appellants’ challenge the trial court’s decisions to limit certain cross-
    examination, to permit the government to elicit emotional testimony from Jaye’s
    mother, and to excuse Jaye after he testified in the government’s case. We review
    the trial judge’s evidentiary decisions for abuse of discretion, deferring to the trial
    court when it “considers the relevance and potential prejudice of evidence.” Johnson
    v. United States, 
    960 A.2d 281
    , 294 (D.C. 2008). Any issues to which appellants
    did not object before the trial court are reviewed for plain error. See Lowery v.
    United States, 
    3 A.3d 1169
    , 1172 (D.C. 2010). 21 We find no abuse of discretion or
    plain error.
    
    21 Jones v
    . United States, 
    127 A.3d 1173
    , 1187 (D.C. 2015) (“Under the plain
    error doctrine, appellant must establish (1) that the trial judge committed error; (2)
    that the error was plain, i.e., clear or obvious; (3) that the error affected his
    substantial rights; and (4) that a failure to correct the error would seriously affect the
    fairness, integrity, or public reputation of judicial proceedings.”).
    47
    First, the trial court did not unduly limit the defense’s cross-examination of
    the witnesses. Appellants argue that the trial court abused its discretion by limiting
    cross-examination of a government witness concerning a theory of the case: that the
    assault was not motivated by bias, but by events earlier in the evening. 22 During
    Alicia’s direct examination, the government only asked her about the attack that
    occurred outside on the corner of Sherman and Harvard streets, and did not ask her
    about any earlier events that occurred at Leo’s house. Because of the limited scope
    of Alicia’s direct, appellants tried, but were prohibited from, asking Alicia on cross
    about the events earlier in the evening. 23 When the defense attempted to ask Ashley
    and Jaye on cross-examination about the physical altercation at Leo’s house earlier
    in the evening, Ashley denied witnessing a physical fight involving Jaye and Jaye
    denied involvement in an earlier altercation or argument. “[I]t is not improper for
    the trial court to limit the scope of the cross-examination to matters raised on direct-
    examination.” Guzman v. United States, 
    769 A.2d 785
    , 794 (D.C. 2001). Given the
    22
    Two weeks prior to trial, the government filed a motion in limine to
    preclude the defendants from introducing testimony about the earlier incident. The
    trial court granted the motion, ruling that appellants could not elicit such testimony
    unless it was relevant to a legally cognizable issue, e.g., to issues of identity or a
    theory of self-defense; in other words, appellants could not elicit such testimony to
    support a theory of that Jaye provoked, and thereby deserved, the assault.
    23
    Despite the limited scope of direct, defense counsel attempted to ask Alicia,
    in a multitude of ways, about her son being involved in a fight at Leo’s home earlier
    in the evening. On at least seven occasions, the court sustained the government’s
    objections to the defense’s questions.
    48
    limited scope of the direct examination of the witnesses, we conclude that the trial
    court did not abuse its discretion in limiting the scope of the witnesses’ cross-
    examination.
    Moreover, despite the appropriateness of the trial court’s limitation of such
    cross-examination, appellants cannot convincingly argue that they were prejudiced.
    The defense developed its alternative theory of the case – that the attack was not
    motivated by bias, but by an incident that occurred earlier in the day – by calling a
    number of non-victim witnesses who testified regarding the earlier altercation and
    by discussing that confrontation during closing arguments. 24
    Second, appellants argue that the trial court abused its discretion by permitting
    the government to elicit emotional testimony from Alicia to improperly play to the
    jury’s sympathy.    Alicia provided emotional testimony in her direct, and the
    government played Alicia’s 911 call at the beginning of its closing arguments.
    24
    Over the government’s objection, the trial court permitted testimony from
    three separate witnesses to support the defense’s motive theory: (1) that Leo and
    another man were about to “jump” Christina outside of the party earlier in the
    evening; (2) that a commotion took place outside of Leo’s house, and Leo and
    another man appeared as if they were about to fight Christina; and (3) that “the boy,”
    Jaye, “got into it” with Christina. Then, in closing arguments, defense counsel
    references Jaye “going back and forth with people” and “mouthing off” earlier at
    Leo’s house.
    49
    Because appellants only objected to one of the government’s question to Alicia on
    direct, we review the trial court’s admission of that testimony for abuse of discretion,
    and we review the remaining testimony and arguments for plain error. See 
    Johnson, 960 A.2d at 294
    ; 
    Lowery, 3 A.3d at 1172
    .
    While testifying, Alicia referred to her son Jaye as “my baby” and cried on
    the stand, stating, “I thought my baby was dead because we were shaking him and
    he wouldn’t move. He was unconscious, but I thought he was dead.” At the end of
    her direct testimony, the government asked Alicia to tell the jury how the incident
    had affected her. Then, over a defense objection as to relevance, Alicia detailed
    flashbacks, visits to a psychiatrist and therapist, and difficulty eating and drinking.
    She stated, “I can’t get that vision of my baby’s face being stomped on and the
    cutting and the bleeding and all that, I just can’t get it out of my mind for nothing.”
    The government began its closing argument by replaying Alicia’s 911 call, which
    the defense alleges was highly emotional but contained no facts that would assist in
    identifying the perpetrators. In closing, the prosecution referred to the “pain in her
    voice” and in rebuttal, reiterated “the pain, the hurt, the emotion that Alicia Davis
    had when she testified.”
    50
    The trial court did not err, let alone commit plain error, in permitting Alicia’s
    emotional testimony. Alicia testified to her firsthand knowledge of the attack she
    witnessed, which was highly probative of the truth of the events. Appellants
    attacked Alicia’s credibility and her ability to accurately identify the perpetrators;
    her emotional response was one factor that could assist the jury in weighing her
    credibility and truthfulness, and was therefore relevant. See Brocksmith v. United
    States,

    to permit the government during closing argument to play Alicia’s 911 call or to
    refer to the “pain in her voice,” all of which conveyed the seriousness of the assault
    and was another means of assessing Alicia’s credibility. Further, the trial court did
    not abuse its discretion by allowing Alicia to testify to how the incident affected her.

    Third, the facts belie appellants’ argument that the trial court erred in excusing
    complaining witness Jaye at the close of the government’s case, rather than ensuring
    that he was available for recall in the defense’s case.           At the close of the
    government’s case, the trial judge clearly communicated to Christopher’s defense
    counsel that he could subpoena Jaye, but defense counsel stated that he was unsure
    whether to recall Jaye to testify about the alleged earlier fight, as the testimony would
    have been cumulative of what Jaye testified to in the government’s case. Further,
    the trial court clarified with defense counsel that “I thought your defense was that
    ya’ll wasn’t even there.” After consulting with Christopher, defense counsel stated
    that Jaye could be dismissed. We can therefore find no abuse of discretion.
    VI.    Conclusion
    We conclude that the trial court conveyed but-for causation when it instructed
    the jury that there may be “additional motives” other than bias or prejudice that
    caused appellants to attack Jaye, but nonetheless, the jury may convict appellants if
    it finds beyond a reasonable doubt that they committed the aforementioned crimes
    52
    “because of prejudice based on the actual or perceived sexual orientation of” Jaye
    Davis. The trial court, in responding to the jury’s note requesting clarification on
    causation, did not abuse its discretion in directing the jury back to the original
    instruction. Further, the evidence was sufficient to sustain the findings that
    appellants attacked Jaye because of their bias toward him based on his sexual
    orientation. We find appellants’ remaining contentions to be without merit.
    Affirmed.
    53
    FISHER, Senior Judge, concurring: I agree that the original jury instructions
    adequately conveyed the requirement that, before appellants could receive enhanced
    sentences, prejudice based on the actual or perceived sexual orientation of Jaye
    Davis had to be a but-for cause of the assault. But the jury’s note reflected
    uncertainty about how important that motive had to be in relation to others, and I
    question whether the response was sufficient to explain that, in the absence of such
    prejudice, the assault would not have occurred.
    Defense counsel did not request such language, however.            Counsel for
    Christina Lucas suggested that “we just direct them back to the jury instructions in
    regard to their, as an answer to their question.” Christopher Lucas’s attorney argued,
    “Our position basically is, as you stated, the government has to prove beyond a
    reasonable doubt the bias which caused the assault. . . . It’s just a reasonable doubt
    question.” The supplemental instruction accommodated both requests and easily
    survives plain error review.
    54
    BECKWITH, Associate Judge, dissenting: The deliberating jury in this case
    sent a note asking for guidance about how much of a role appellants’ bias had to play
    in the assault of the complainant in order for the jury to convict them of the bias-
    related enhancement. Did it have to find that appellants’ prejudice based on sexual
    orientation was “the only reason a crime was committed”? Did it have to find that
    it was “the primary reason a crime was committed”? The trial court answered the
    jury’s question by reiterating the instruction on causation that it had already given
    the jury—a response that Chief Judge Blackburne-Rigsby concludes was sufficient
    to clear up any confusion the jury may have had about the causal relationship
    between the bias and the assault for purposes of the enhancement for bias-related
    crimes. Ante at 32-39. Unlike the Chief Judge, my concurring colleague, Judge
    Fisher, “question[s] whether the response was sufficient to explain that, in the
    absence of such prejudice, the assault would not have occurred.” Ante at 53. Judge
    Fisher nevertheless rejects appellants’ claim of instructional error on plain error
    grounds based on his view that the appellants’ objection was inadequate to preserve
    the challenge.
    55
    While I agree with Chief Judge Blackburne-Rigsby that the appellants
    preserved their challenge to the trial court’s response to the jury question, 1 ante at
    32 n.15, and I agree with both of my colleagues that the Bias-Related Crime Act
    requires the government to establish that the accused would not have committed the
    underlying crime but for the accused’s prejudice against the complainant’s protected
    characteristic, ante at 21-26, I respectfully dissent from Chief Judge Blackburne-
    Rigsby’s conclusion that the trial court adequately dispelled the jury’s confusion by
    repeating its prior instruction.

    See Zeledon v. United States, 
    770 A.2d 972
    , 975 (D.C. 2001); Whitaker v.
    United States, 
    617 A.2d 499
    , 508 (D.C. 1992) (noting that even an inaccurate or
    unclear request for instruction may be sufficient if it “directed the mind to the legal
    principle, and . . . required that a correct instruction be given with regard thereto”).
    Judge Fisher’s description of the extensive discussion of the jury note is a
    simplification that leaves out several key facts relevant to whether appellants
    preserved their objection, including that the discussion took several turns as the
    parties considered the options; that one appellant mentioned the need for a “[v]ery
    clear nexus between the bias identified in the statute and the assault finding” and the
    need for clarity “that it was the bias that was the source of the assault;” that the
    prosecutor urged the court to answer the jury’s specific question; that the court
    expressed its disinclination to instruct the jury about whether bias had to be the only
    or the primary reason a crime was committed; and that the judge made a decision so
    we have a ruling to review. As in Zeledon, the trial court’s failure to reinstruct the
    jury accurately did not stem from the content of appellants’ suggestions “but from
    her belief that no instruction was 
    necessary.” 770 A.2d at 976
    . “[T]he plain error
    rule is not meant to be punitive; instead its purpose is to allow the trial judge [to]
    fully . . . consider issues and thereby avoid potential error.” Williams v. United
    States, 
    966 A.2d 844
    , 847 (D.C. 2009) (internal quotation marks and citation
    omitted). The trial court here had every opportunity to avoid error.
    56
    As Judge Fisher points out in concurrence, the jury’s question reflected its
    uncertainty about what role bias played and “how important that motive had to be in
    relation to others” in its determination of appellants’ guilt under the BRCA. The
    right answer to the jury’s inquiry, as the court holds today, was that prejudice had to
    be a but-for cause of the crime. Yet instead of addressing the uncertainty directly—
    and heeding the prosecutor’s assertion that it was “important that the Court at least
    respond to the specific question”—the court, stating that “[t]here’s no case law
    addressing that point specifically” and that it “honestly [didn’t] know” whether bias
    “has to be the only reason,” fell back on the instruction that caused the jury to seek
    guidance in the first place. Even assuming the initial instruction fully conveyed the
    bias enhancement’s but-for causation requirement, 2 the jury didn’t grasp it, and once
    2
    I disagree with the majority that the original instruction adequately
    conveyed the concept of but-for causation to the jury—in particular, the court’s
    conclusion that, because the phrase “because of” has been interpreted to signify “but-
    for” causation in statutes, a lay jury would interpret “because of” in a jury instruction
    to convey the same meaning. Ante at 29-31. The jurors’ expressed confusion about
    the jury instruction in this case demonstrates that the colloquial use of the phrase
    “because of” does not necessarily convey the nuances of a complicated legal
    concept. Christina Lucas illustrates this well with the example in her supplemental
    brief about the friend who tells you she is going to the store because she needs milk,
    bread, and eggs. Without further information, nothing about that statement indicates
    that each of those three products is a but-for cause of her trip. If you gave your
    friend a dozen eggs, she might still go to the store to buy milk and bread, or she
    might not, because the eggs were in fact the but-for cause of her trip and she could
    wait until later to pick up milk and bread. In sum, as Ms. Lucas states in her brief,
    the “demand for but-for causality in the criminal law does not perfectly align with
    everyday speech.”
    57
    the jury sought clarity regarding a controlling issue in the case, the court was
    required to clear it up “with concrete accuracy.” Bollenbach v. United States, 
    326 U.S. 607
    , 612-13 (1946). I would hold that the trial court failed to do so, that it
    affected the verdict, and that the bias enhancements should be reversed.
