    SUMMARY**
    Criminal Law
    The panel affirmed a defendant’s convictions, vacated his
    sentence, and remanded for resentencing in a case in which
    the defendant robbed a victim at gun point after luring him to
    a train station by posting an advertisement for a used car on
    Craigslist.
    At the defendant’s first trial, a jury found the defendant
    guilty of being a felon in possession of a firearm (18 U.S.C.
    § 922(g)(1)), but did not reach a unanimous verdict on a
    Hobbs Act robbery count (18 U.S.C. § 1951(a)) and a
    dependent count of brandishing a firearm during and in
    relation to a crime of violence (18 U.S.C. § 924(c)(1)(A)(ii)).
    At retrial, a second jury convicted the defendant on the Hobbs
    Act robbery and brandishing counts.
    The panel held that there was sufficient evidence at the
    first trial to satisfy the interstate-commerce element of the
    Hobbs Act because a rational jury could have concluded that
    the defendant advertised a commercial transaction on
    Craigslist, a website that facilitates interstate commerce, to
    facilitate the robbery. Because there was sufficient evidence
    presented at the first trial to sustain a conviction, there was a
    fortiori sufficient evidence presented at the retrial.

    was constructively amended during his second trial when the

    UNITED STATES V. LUONG                        3
    government presented additional theories to satisfy the
    interstate-commerce element of Hobbs Act robbery, the panel
    wrote that the indictment was not required to allege facts
    specifically outlining how the defendant’s use of Craigslist or
    a stolen credit card affected interstate commerce.
    The panel held that because the jury was unanimous in
    concluding that the defendant’s robbery affected interstate
    commerce, and the government’s theories supporting the
    interstate-commerce element were based in law, a specific
    unanimity instruction was not warranted.
    The panel held that the district court did not err in giving
    an instruction that an effect on interstate commerce can be
    established by proof of a probable or potential impact, which
    can be slight but not speculative. The panel added that any
    error would have been harmless.
    Assuming that the defendant is correct that the
    prosecution incorrectly stated the law when it argued to the
    jury that the defendant’s robbery had an effect on interstate
    commerce based upon “the use of interstate commerce,” the
    panel held that the district court did not abuse its discretion in
    concluding that this did not rise to the level of incurable
    misconduct. The panel held that the prosecutor’s statements
    attacking the credibility of defense counsel and telling the
    jury that it could only carry out its duty by siding with the
    government were plainly improper, but do not warrant
    reversal, in the context of both attorneys’ arguments, the
    district court’s directive to follow the instructions, the jury
    instructions themselves, and the government’s statements at
    other times during the argument that the jury must weigh all
    of the evidence to reach its conclusion.
    4                 UNITED STATES V. LUONG
    Reviewing for plain error, the panel held that it was clear
    error under Rehaif v. United States, 
    139 S. Ct. 2191
    (2019),
    for the jury to not have been instructed that knowledge of
    felon status was an element of felon-in-possession count, but
    even if the district court had so instructed the jury, there is no
    reasonable probability that the jury would have reached a
    different verdict, and the error therefore did not affect the
    defendant’s substantial rights, nor the fairness, integrity, or
    public reputation of the first trial.
    Following United States v. Dominguez, 
    954 F.3d 1251
    (9th Cir. 2020), the panel held that Hobbs Act robbery
    constitutes a predicate crime of violence under 18 U.S.C.
    § 924(c)(3)(A).
    The panel held that insofar as the district court declined
    to give the defendant a downward adjustment for acceptance
    of responsibility under U.S.S.G. § 3E1.1(a) based on his
    counsel’s challenges to the federal government’s jurisdiction
    to prosecute the alleged offense and to the evidence going to
    that question at trial, the district court erred as a matter of
    law. Noting that the district court would have acted
    according to law by denying the adjustment for the
    defendant’s lack of contrition, the panel vacated the sentence
    and remanded for resentencing, leaving it for the district court
    to make a factual finding on contrition in the first instance.

    OPINION
    SMITH, District Judge:
    Appellant Tuan Ngoc Luong (“Luong”) robbed Joel
    Montellano at gun point after luring him to a Bay Area Rapid
    Transit (“BART”) train station in Castro Valley, California,
    by posting an advertisement for a used car on a Craigslist site.
    On March 26, 2015, a grand jury returned a three-count
    indictment charging Luong with (1) a violation of the Hobbs
    Act, 18 U.S.C. § 1951(a) (count 1); (2) brandishing a firearm
    during and in relation to a crime of violence in violation of
    18 U.S.C. § 924(c)(1)(A)(ii) (count 2); and (3) being a felon
    in possession of a firearm in violation of 18 U.S.C.
    § 922(g)(1) (count 3). The sole contested issue at trial was
    whether the government’s evidence was sufficient to establish
    that Luong’s robbery had an effect on interstate commerce, as
    required to sustain a conviction under the Hobbs Act. See
    18 U.S.C. § 1951(a).
    The jury, after deliberating, found Luong guilty of being
    a felon in possession of a firearm, but did not reach a
    unanimous verdict on the Hobbs Act robbery count and
    dependent § 924(c) count. The district court declared a
    mistrial on counts 1 and 2. At retrial, the government
    expanded its interstate-commerce theory and presented
    additional evidence that the robbery affected interstate
    6                  UNITED STATES V. LUONG
    commerce through the testimony of a second Craigslist
    representative, as well as testimony that Luong’s attempted
    use of a stolen debit card1 caused electronic transmissions to
    travel to out-of-state servers. The second jury convicted
    Luong on counts 1 and 2, and the district court sentenced him
    to 144 months’ imprisonment followed by three years’
    supervised release.
    Luong appeals from his convictions and sentence,
    pressing several arguments.          We conclude that the
    government presented sufficient evidence to convict Luong
    on counts 1 and 2 at the first trial, and a fortiori the second
    trial, and affirm Luong’s conviction on all counts, but we
    vacate Luong’s sentence and remand for resentencing on
    count 3.
    BACKGROUND
    We recount the facts underlying the robbery, which are
    largely undisputed, in the light most favorable to the
    government. See United States v. Grovo, 
    826 F.3d 1207
    ,
    1213–14 (9th Cir. 2016) (citing United States v. Nevils,
    
    598 F.3d 1158
    , 1163–64 (9th Cir. 2010) (en banc)). On
    February 15, 2015, Luong posted an advertisement on
    Craigslist’s San Francisco Bay Area website for a 1996 Acura
    Integra, asking “$1100 or OBO cash only.” Specifically,
    Luong posted the advertisement, free of charge, on the
    “Dublin/Pleasanton/Livermore” subsection of the “East Bay”
    section of the “S.F. Bay Area” Craigslist site. Luong had
    posted, but deleted, a similar advertisement three days earlier
    1
    The terms “debit card” and “credit card” are used interchangeably
    throughout this opinion.
    UNITED STATES V. LUONG                     7
    on a different, but close by, subsection of the “East Bay”
    section of the “S.F. Bay Area” site.
    Joel Montellano, who lived in Hayward, California, saw
    the advertisement and arranged to meet Luong shortly
    thereafter. Both Montellano and Luong lived in the San
    Francisco Bay Area, and the San Francisco-based Craigslist
    website refers to itself as “a local service” “that provides
    local classifieds and forums.” Luong called Montellano and
    said his name was “Michael.” They arranged to meet later
    that night at the Castro Valley BART train station for
    Montellano to inspect the car.
    Montellano’s girlfriend drove him to the BART station.
    Once there, at Luong’s suggestion, Luong and Montellano
    took the car for a test drive and Montellano agreed to buy the
    car. Luong told Montellano that his wife had the title for the
    car and directed Montellano to drive to Luong’s house.
    When they arrived, Montellano got out of the Acura to further
    inspect the car. Luong drew a pistol, pointed it at
    Montellano, and shouted:           “give me your money.”
    Montellano told Luong that the money was not with him, but
    was instead with his girlfriend at the BART station. At
    Luong’s direction, and with Luong’s gun pointed at him,
    Montellano placed his iPhone, his girlfriend’s debit card, and
    his U.S. Department of Veterans Affairs medical card on the
    car’s trunk. He provided Luong with an incorrect PIN for the
    debit card. Luong left the scene in the Acura. Montellano
    ran back to the BART station, and once there, his girlfriend
    called 911.
    About thirty minutes after the robbery, Luong attempted
    to use the stolen debit card at nearby Citibank and Bank of
    America ATMs, but was unable to withdraw money using the
    8                UNITED STATES V. LUONG
    incorrect PIN. Two days later, law enforcement arrested
    Luong after posing as a potential buyer for the Acura. At the
    time of his arrest, Luong possessed a semi-automatic pistol
    and ammunition.
    At Luong’s first trial, the government solely relied on
    Luong’s use of Craigslist to establish an effect on interstate
    commerce. From the evidence presented at trial, viewing the
    facts in the light most favorable to the government, a rational
    factfinder could have concluded the following: Craigslist is
    a “local classified and forums service” based in San
    Francisco, California. It is “primarily community moderated
    and mostly free.” It displays user-posted classifieds in
    categories such as housing, various items for sale, and job
    postings.
    Each month, Craigslist gets approximately 50 billion page
    views, approximately 60 million people in the United States
    use Craigslist, and 80 million advertisements are posted to the
    site. While it has an international audience, “Craigslist is not
    one national or worldwide site, [rather,] it’s multiple local
    sites around the world,” including 700 sites in more than
    70 countries, with approximately 28 of those sites in
    California. Anyone in the world with an Internet connection
    may view any of the Craigslist sites. A user cannot search
    multiple Craigslist sites at once. Instead, a user must select
    a particular location site before he or she can search. The
    website’s policies prohibit “[n]onlocal content” and
    “[p]osting the same ad to multiple locations.” And while
    Craigslist has expanded beyond San Francisco, “it still retains
    that focus on local searches and local postings” and it
    “emphasizes and encourages local face-to-face transactions
    at a number of places in its website.”
    UNITED STATES V. LUONG                       9
    On a Craigslist site’s opening page and on its for-sale-by-
    owner car pages, Craigslist provides links to “nearby cl” sites
    to allow users to access easily the Craigslist sites associated
    with nearby physical locations. For example, from the San
    Francisco car site (on which Luong posted the advertisement
    used to lure Montellano), a user can find the link to the Reno,
    Nevada, Craigslist site, in addition to other nearby California
    car sites. Similarly, on the Reno site, the San Francisco site
    is listed as a nearby site. The jury further heard that on the
    Craigslist Reno car site, for example, cars from California
    and Oregon were offered for sale.
    The government offered anecdotal evidence of users
    buying and selling vehicles by using Craigslist sites in other
    states. Montellano testified that he had sold a motorcycle to
    someone from Nevada who traveled to California for the
    transaction after he posted it on Craigslist’s San Francisco
    Bay Area site. Special Agent Brian Koh testified that he had
    used the Washington, D.C. Craigslist site while living in the
    Bay Area, because he might have needed a car for a
    temporary assignment in D.C.
    Craigslist maintains redundant computer servers in
    California and Arizona. A Craigslist representative, William
    Powell, testified that he was not “certain if the data is on both
    [servers] or one at a time,” but that they are intended to
    provide a backup if one server fails. He testified that it was
    his understanding that if the California server failed, the
    Arizona server would provide the data to the Internet user.

    DISCUSSION
    I. Hobbs Act Jurisdictional Nexus
    The court reviews de novo the sufficiency of the
    evidence, viewing “the evidence in the light most favorable
    to the prosecution and ask[ing] whether any rational trier of
    fact could have found the essential elements of the crime
    beyond a reasonable doubt.” 
    Grovo, 826 F.3d at 1213
    –14
    (citing 
    Nevils, 598 F.3d at 1163
    –64). “The district court’s
    interpretation of a criminal statute and the scope of the
    conduct covered by the statute is a question of law reviewed
    de novo.” United States v. Sarkisian, 
    197 F.3d 966
    , 984 (9th
    Cir. 1999) (citing United States v. Ripinsky, 
    20 F.3d 359
    , 361
    (9th Cir. 1994)). If there was insufficient evidence to support
    the convictions on counts 1 and 2 at Luong’s first trial, his
    convictions on those counts at the second trial must be
    vacated because they would violate the Double Jeopardy
    Clause of the Fifth Amendment. See United States v. Brown,
    
    785 F.3d 1337
    , 1350 (9th Cir. 2015) (stating that, if the
    evidence is insufficient to establish guilt at the defendant’s
    first trial, retrial is foreclosed). Thus, we focus our discussion
    on the sufficiency of the government’s evidence at Luong’s
    first trial.
    The relevant offense of conviction, established by the
    Hobbs Act, provides in pertinent part that:
    Whoever in any way or degree obstructs,
    delays, or affects commerce or the movement
    of any article or commodity in commerce, by
    robbery or extortion or attempts or conspires
    so to do, or commits or threatens physical
    violence to any person or property in
    UNITED STATES V. LUONG                      11
    furtherance of a plan or purpose to do
    anything in violation of this section shall be
    fined under this title or imprisoned not more
    than twenty years, or both.
    18 U.S.C. § 1951(a) (emphasis added). The Hobbs Act
    defines “commerce,” in pertinent part, as “all commerce
    between any point in a State . . . and any point outside
    thereof; all commerce between points within the same State
    through any place outside such State; and all other commerce
    over which the United States has jurisdiction.” 18 U.S.C.
    § 1951(b)(3).
    The Supreme Court has held that the Hobbs Act “speaks
    in broad language, manifesting a purpose to use all the
    constitutional power Congress has to punish interference with
    interstate commerce by extortion, robbery or physical
    violence. The Act outlaws such interference ‘in any way or
    degree.’” Stirone v. United States, 
    361 U.S. 212
    , 215 (1960)
    (quoting 18 U.S.C. § 1951(a)); see also Taylor v. United
    States, 
    136 S. Ct. 2074
    , 2077 (2016) (stating that the Hobbs
    Act “criminalizes robberies and attempted robberies that
    affect any commerce ‘over which the United States has
    jurisdiction’”); United States v. Lynch, 
    437 F.3d 902
    , 908 (9th
    Cir. 2006) (“Lynch IV”). This court has similarly held that,
    when Congress chooses to use the words “affecting interstate
    commerce,” it intends “to regulate to the outer limits of its
    Commerce Clause authority[.]” 
    Brown, 785 F.3d at 1351
    .
    The Commerce Clause of the United States Constitution
    grants Congress the authority to regulate commerce in “three
    broad categories of activity”: (1) “the use of the channels of
    interstate commerce[;]” (2) “the instrumentalities of interstate
    commerce, or persons or things in interstate commerce, even
    though the threat may come only from intrastate activities[;]”
    12                 UNITED STATES V. LUONG
    and (3) “those activities having a substantial relation to
    interstate commerce, . . . i.e., those activities that substantially
    affect interstate commerce.” United States v. Morrison,
    
    529 U.S. 598
    , 608–09 (2000) (quotation marks and citations
    omitted). This broad authority, however, does not permit the
    federal government “to pile inference upon inference in a
    manner that would bid fair to convert congressional authority
    under the Commerce Clause to a general police power of the
    sort retained by the States.” United States v. Lopez, 
    514 U.S. 549
    , 567 (1995).
    Consistent with this broad reading, the Hobbs Act
    interstate-commerce element is satisfied by actual impact
    when the government “establish[es] that a defendant’s acts
    had a de minimis effect on interstate commerce.” Lynch 
    IV, 437 F.3d at 908
    (citing United States v. Atcheson, 
    94 F.3d 1237
    , 1241 (9th Cir. 1996); United States v. Phillips,
    
    577 F.2d 495
    , 501 (9th Cir. 1978)); see also 
    Atcheson, 94 F.3d at 1243
    (noting that connection to interstate
    commerce need only be “slight” (quoting United States v.
    Huynh, 
    60 F.3d 1386
    , 1389 (9th Cir. 1995))). Or, in the
    absence of actual impact, the interstate-commerce nexus
    requirement is met “‘by proof of a probable or potential
    impact’ on interstate commerce.” Lynch 
    IV, 437 F.3d at 909
    (quoting 
    Huynh, 60 F.3d at 1389
    ).
    By using a website that facilitates interstate commerce
    (like Craigslist) to advertise a commercial transaction, Luong
    necessarily affected or potentially affected “commerce over
    which the United States has jurisdiction.” 18 U.S.C.
    § 1951(b)(3). As the evidence at Luong’s first trial
    demonstrated, Craigslist is an Internet site that facilitates
    commerce on a national and international level. Cf. United
    States v. Horne, 
    474 F.3d 1004
    , 1006 (7th Cir. 2007) (holding
    UNITED STATES V. LUONG                        13
    eBay “is an avenue of interstate commerce, like an interstate
    highway or long-distance telephone service”). The evidence
    presented at the first trial included, for example, that the
    victim previously sold a motorcycle on Craigslist to a Nevada
    buyer who traveled from Nevada to purchase and collect the
    motorcycle in California. The victim further testified that he
    received inquiries on other vehicles he posted on the Bay
    Area site from prospective buyers in Nevada, Texas, and
    Florida. He also testified that he had seen car advertisements
    posted on the Bay Area site from sellers located in Nevada,
    Oregon, Texas, Minnesota, and other states. Finally, the jury
    heard that the Reno, Nevada site contained advertisements
    from sellers in California and Oregon.
    Moreover, despite Craigslist’s stated aspirational goal of
    facilitating local transactions, the government highlighted at
    trial that Craigslist sites allow a user to search other localities
    across state lines. Specifically, local sites provide drop-down
    menus that include links to sites for nearby cities. For
    example, the Bay Area site links users to the Reno site, which
    links its users to the Bay Area site, other California local
    sites, and at least one site in Oregon. The jury also heard that
    the investigating agent in this case, while still in the Bay
    Area, once searched Washington, D.C.’s site for a car to
    purchase before he was transferred there on long-term
    assignment. From all of this, and viewing the evidence in the
    light most favorable to the government, a jury could
    reasonably conclude that the Craigslist Bay Area site
    facilitated commercial transactions beyond the local area and
    operated as an interstate market for used vehicles. Cf. 
    Horne, 474 F.3d at 1006
    . Thus, Craigslist transactions are
    “commerce over which the United States has jurisdiction”
    and a robbery occurring within the context of such a
    transaction “affect[s] . . . commerce ‘over which the United
    14                UNITED STATES V. LUONG
    States has jurisdiction.’” 
    Taylor, 136 S. Ct. at 2077
    (quoting
    18 U.S.C. § 1951(b)(3)).
    Even if we view Craigslist as facilitating only local
    transactions, the interstate-commerce jurisdictional nexus is
    still met here. The Supreme Court’s opinion in Taylor v.
    United States, 
    136 S. Ct. 2074
    (2016), guides our analysis. In
    Taylor, the Supreme Court concluded that, because Congress
    has the authority to regulate the national marijuana market,
    including the purely intrastate production, possession, and
    sale of marijuana, based on its aggregate effect on interstate
    commerce, so too may Congress regulate intrastate marijuana
    theft under the Hobbs Act.
    Id. at 2077.
    While the Court in
    Taylor limited its holding “to cases in which the defendant
    targets drug dealers for the purpose of stealing drugs or drug
    proceeds[,]” and declined to “resolve what the Government
    must prove to establish Hobbs Act robbery where some other
    type of business or victim is targeted[,]”
    id. at 2082,
    the logic
    employed in Taylor readily applies to the facts of this case.
    Therefore, the Hobbs Act’s interstate-commerce element is
    satisfied in cases like this one, where the government
    demonstrates that a person used a commercial website to
    advertise a commercial transaction in order to facilitate a
    robbery.
    Luong advances several arguments against a jurisdictional
    nexus, none of which is convincing. First, Luong argues that
    the Ninth Circuit Model Criminal Jury Instructions
    undermine the government’s theory of the case. The Ninth
    Circuit Model Criminal Jury Instruction for the “affecting
    interstate commerce” element of the Hobbs Act was updated
    in December 2016 to state that, “[c]onduct affects interstate
    commerce if it in any way involves, interferes with, changes,
    or alters the movement or transportation or flow of goods,
    UNITED STATES V. LUONG                      15
    merchandise, money, or other property in commerce between
    or among the states or between the United States and a
    foreign country.” 9th Cir. Crim. Jury Instr. 8.143B. Luong
    avers that the government’s Internet data-transmission theory
    is insufficient under the model instruction, emphasizing that
    the criminal conduct must affect “goods, merchandise,
    money, or other property in commerce.”
    This argument fails. Pattern jury instructions are
    not authoritative legal pronouncements. See Caveat, 9th Cir.
    Crim. Jury Instr. iv, available at http://www3.ce9.uscourts.gov/
    jury-instructions/sites/default/files/WPD/Criminal_Instructions
    _2019_12_0.pdf (“The Ninth Circuit Court of Appeals does
    not adopt these instructions as definitive.             Indeed,
    occasionally the correctness of a given instruction may be the
    subject of a Ninth Circuit opinion.”). In any event, we do not
    rely on the government’s data-transmission theory, and
    instead we conclude that the jurisdictional element is met
    because Luong’s use of a service like Craigslist had an actual
    impact on interstate commerce. For this reason, whether the
    data-transmission theory comports with the model instruction
    is of no import here.
    Second, Luong argues that the Hobbs Act’s jurisdictional
    language—requiring that the offense conduct “obstruct[],
    delay[], or affect[] commerce,” 18 U.S.C. § 1951(a)—
    provides a narrower jurisdictional grant than those criminal
    statutes requiring the defendant to “us[e] the mail or any
    facility or means of interstate . . . commerce,” see, e.g., 18
    U.S.C. § 2422(b). In contrast, the government asserted
    during oral argument that the mere use of any instrumentality
    of interstate commerce is sufficient under the Hobbs Act. We
    do not need to reach this question, however, because the
    evidence was sufficient to show that Luong clearly affected
    16               UNITED STATES V. LUONG
    interstate commerce by robbing his victim as part of a
    commercial transaction facilitated by a website that forms an
    interstate market for used cars.
    This conclusion does not render the interstate-commerce
    element of the Hobbs Act superfluous. See 
    Taylor, 136 S. Ct. at 2081
    (stating that while the Hobbs Act, “unlike the
    criminal provisions of the [Controlled Substances Act],
    applies to forms of conduct that, even in the aggregate, may
    not substantially affect commerce,” the Hobbs Act interstate-
    commerce element is not superfluous). While the Hobbs Act
    is implicated by robberies involving commercial transactions
    facilitated by electronic marketplaces, this does not mean
    every local robbery is a Hobbs Act robbery simply because
    the robber touched his smart phone to check the weather or
    plan a get-away route. See, e.g., Lynch 
    IV, 437 F.3d at 909
    –10 (adopting depletion-of-assets test in Hobbs Act
    cases involving crimes directed toward individuals with an
    indirect effect on interstate commerce (citing United States v.
    Collins, 
    40 F.3d 95
    , 99 (5th Cir. 1994))); United States v.
    Turner, 
    272 F.3d 380
    , 387 (6th Cir. 2001) (concluding that
    there was insufficient evidence to satisfy interstate-commerce
    element because the government did not demonstrate that the
    victim, “as an individual victim, had a substantial connection
    to ‘a business engaged in interstate commerce,’ or that the
    defendants were motivated by [the victim]’s connection to
    interstate commerce” (internal citation omitted)), amended
    sub nom. United States v. James, 
    280 F.3d 1078
    (6th Cir.
    2002); United States v. Peterson, 
    236 F.3d 848
    , 853 (7th Cir.
    2001) (noting that “the government rightly concedes that the
    out-of-state origin of the currency alone is insufficient to
    satisfy the commerce element of the Hobbs Act” (quotation
    omitted)), abrogated on other grounds by Taylor, 136 S. Ct.
    UNITED STATES V. LUONG                      17
    2074. In this case, the Craigslist website was an integral
    element of the robbery, not a peripheral afterthought.
    Accordingly, because a rational juror could have
    concluded that Luong advertised a commercial transaction on
    Craigslist to facilitate the robbery, the evidence was sufficient
    to satisfy the interstate-commerce element of the Hobbs Act.
    Because there was sufficient evidence presented at Luong’s
    first trial to sustain a conviction, there was a fortiori
    sufficient evidence presented at Luong’s retrial.
    II. Constructive Amendment of the Indictment
    The court reviews de novo an argument that the
    indictment was constructively amended. United States v.
    Adamson, 
    291 F.3d 606
    , 612 (9th Cir. 2002).
    It is axiomatic that “after an indictment has been
    returned[,] its charges may not be broadened through
    amendment except by the grand jury itself.” 
    Stirone, 361 U.S. at 215
    –16 (citing Ex parte Bain, 
    121 U.S. 1
    , 7
    (1887)). “[A] court cannot permit a defendant to be tried on
    charges that are not made in the indictment against him.”
    Id. at 217.
    A constructive amendment to the indictment occurs
    “where . . . there is a complex of facts presented at trial
    distinctly different from those set forth in the charging
    instrument.” United States v. Hui Hsiung, 
    778 F.3d 738
    , 757
    (9th Cir. 2015) (alterations omitted) (quoting 
    Adamson, 291 F.3d at 615
    ). If the court determines that the indictment
    was constructively amended, a reversal is always in order.
    
    Adamson, 291 F.3d at 615
    .
    Count 1 of the indictment, alleging a violation of the
    Hobbs Act, 18 U.S.C. § 1951(a), states that Luong
    18               UNITED STATES V. LUONG
    knowingly obstructed, delayed, and affected
    commerce and the movement of articles and
    commodities in commerce by robbery, in that
    [he] did unlawfully take and obtain against the
    victim’s will by means of actual and
    threatened force, by violence, and by fear of
    injury to the victim’s person, personal
    property from the victim, namely the victim’s
    iPhone 6, credit card, driver’s license, and
    medical card, by purporting to offer for sale
    on Craigslist, an online marketplace allowing
    users to advertise merchandise and services
    for sale throughout the United States, a 1996
    Acura Integra, and when the victim met the
    defendant in order to purchase the car, the
    defendant robbed the victim at gunpoint.
    Luong argues that the indictment was constructively amended
    during his second trial when the government presented
    additional theories to the jury to satisfy the interstate-
    commerce element. Specifically, Luong argues that the
    indictment, as written, did not allege that he had affected
    interstate commerce by triggering out-of-state electronic
    transmissions by the attempted use of the credit card at an
    ATM after the robbery.
    An indictment generally “is sufficient if it sets forth the
    elements of the charged offense” so as to provide the
    defendant with fair notice of the charges against him and to
    ensure that the defendant is not placed in double jeopardy.
    United States v. Rodriguez, 
    360 F.3d 949
    , 958 (9th Cir. 2004)
    (quoting United States v. Woodruff, 
    50 F.3d 673
    , 676 (9th
    Cir. 1995) (“Woodruff I”)). To secure a conviction for Hobbs
    Act robbery, a grand jury must set forth in the indictment, and
    UNITED STATES V. LUONG                        19
    the government must prove, two elements: “(1) that the
    defendant either committed or attempted to commit a
    robbery, and (2) a nexus between the defendant’s acts and
    interstate commerce.”
    Id. (quoting United
    States v. Woodruff,
    
    122 F.3d 1185
    , 1185 (9th Cir. 1997) (“Woodruff II”)). But
    while “the interstate commerce nexus is an element that ‘must
    be proved at trial[,] . . . it need not . . . be expressly described
    in the indictment.’”
    Id. (quoting Woodruff
    I, 50 F.3d at 677
    ).
    In Woodruff I, the court held that “[a]lthough the indictment
    contained no facts alleging how interstate commerce was
    interfered with, and did not state any theory of interstate
    impact,” the indictment was sufficient on its 
    face. 50 F.3d at 676
    .
    The indictment here alleges that Luong committed Hobbs
    Act robbery by offering a car for sale on Craigslist and then
    robbing the victim at gunpoint of his credit card and other
    personal effects. The government proved as much at the
    second trial. The indictment was not required to allege facts
    specifically outlining how Luong’s use of Craigslist or the
    stolen credit card affected interstate commerce. See
    
    Rodriguez, 360 F.3d at 958
    . Luong was tried on the same
    “complex of facts” as that set forth in the indictment, and
    thus, Luong had notice of the charges against him. See Hui
    
    Hsiung, 778 F.3d at 757
    –58 (finding no constructive
    amendment where the “facts in the indictment necessarily
    supported” the evidence presented at trial and thus “gave fair
    notice” of the facts proved at trial).
    III.    Specific Unanimity Instruction
    Where, as here, the issue has been preserved, the court
    reviews for abuse of discretion the district court’s denial of a
    20               UNITED STATES V. LUONG
    defendant’s request for a specific unanimity instruction.
    United States v. Kim, 
    196 F.3d 1079
    , 1082 (9th Cir. 1999).
    “[I]n the ordinary case, a general instruction that the
    verdict must be unanimous will be sufficient to protect the
    defendant’s rights.” United States v. Anguiano, 
    873 F.2d 1314
    , 1319 (9th Cir. 1989) (quoting United States v.
    Echeverry, 
    719 F.2d 974
    , 974 (9th Cir. 1983)). Under certain
    circumstances, however, a specific unanimity instruction
    should be given, instructing the jury not to return a guilty
    verdict unless it “unanimously agree[s] to a particular set of
    facts.”
    Id. (alteration in
    original) (quoting 
    Echeverry, 719 F.2d at 975
    ). A specific unanimity instruction is necessary
    “where it appears that ‘there is a genuine possibility of jury
    confusion or that a conviction may occur as the result of
    different jurors concluding that the defendant committed . . .
    acts’” consisting of different legal elements. Id. (quoting
    
    Echeverry, 719 F.2d at 975
    ). In general, “jurors are not
    constitutionally required to unanimously agree on alternative
    theories of criminal liability,” and accordingly, no specific
    unanimity instruction is warranted where jurors may find
    criminal liability based on alternative means of committing
    a single element of a crime. 
    Kim, 196 F.3d at 1083
    .
    At his retrial, Luong requested an instruction requiring the
    jury to unanimously agree on the factual basis underpinning
    the interstate-commerce element. The district court declined,
    concluding that the government’s two theories went to the
    same offense element, and accordingly, the jury did not need
    to “agree to the specific means by which interstate commerce
    was affected.” On appeal, Luong contends that the district
    court abused its discretion in failing to give a specific
    unanimity instruction because, in his view, there was “more
    than a ‘genuine possibility’ of jury confusion in this case.”
    UNITED STATES V. LUONG                     21
    The district court did not abuse its discretion in denying
    Luong’s request for a specific unanimity instruction. The
    government’s interstate-commerce theories were alternative
    means the jury could have found satisfied a single element of
    Hobbs Act robbery, and “jurors are not constitutionally
    required to unanimously agree on alternative theories of
    criminal liability.” 
    Kim, 196 F.3d at 1083
    . Because the jury
    was unanimous in concluding that Luong’s robbery affected
    interstate commerce and the government’s theories
    supporting the interstate-commerce element were based in
    law, a specific unanimity instruction was not warranted.
    IV.    Hobbs Act Jury Instruction
    The court reviews de novo Luong’s next preserved claim
    of error: whether the district court erred in crafting the jury
    instruction at Luong’s retrial. See United States v. Hofus,
    
    598 F.3d 1171
    , 1174 (9th Cir. 2010). A district court “has
    substantial latitude” in crafting jury instructions, provided
    that they “fairly and adequately cover the issues presented.”
    United States v. Hicks, 
    217 F.3d 1038
    , 1045 (9th Cir. 2000)
    (quoting United States v. Frega, 
    179 F.3d 793
    , 806 n.16 (9th
    Cir. 1999)). Thus the question on appeal is whether “the
    instructions, viewed as a whole, ‘were misleading or
    inadequate to guide the jury’s deliberation.’” United States
    v. Kaplan, 
    836 F.3d 1199
    , 1215 (9th Cir. 2016) (quoting
    United States v. Moore, 
    109 F.3d 1456
    , 1465 (9th Cir. 1997)
    (en banc)). Jury instructions only require reversal where they
    prejudiced the defendant.
    Id. At the
    retrial, the district court, over Luong’s objection,
    instructed the jury in relevant part that the government was
    required to prove, beyond a reasonable doubt, that
    22               UNITED STATES V. LUONG
    the robbery affected interstate commerce in
    some way. An effect on interstate commerce
    is established by proof of an actual impact,
    however small, or in the absence of an actual
    impact, proof of a probable or potential
    impact. This impact can be slight, but not
    speculative.
    (emphasis added). Luong argues on appeal that this
    instruction misstated the law and allowed the jury to
    impermissibly convict “if it found that his robbery had no
    more than a potential slight impact on interstate commerce.”
    Even putting aside the inquiry into whether there is any
    meaningful difference between a slight potential effect and
    great potential effect when the character of any potential
    effect cannot be known, the district court did not err in giving
    this instruction. This court has intimated that it is sufficient
    for the government to prove a de minimis, probable effect on
    interstate commerce, so long as it is not purely speculative.
    See United States v. Lynch, 
    282 F.3d 1049
    , 1052 (9th Cir.
    2002), overruled on other grounds, 
    437 F.3d 902
    (9th Cir.
    2006) (stating that Atcheson supported a finding of “only a de
    minimis effect on interstate commerce, including a de minimis
    effect that was probable rather than actual” (citing 
    Atcheson, 94 F.3d at 1243
    )); cf. United States v. Reyes, 363 F. App’x
    192, 195 (3d Cir. 2010) (stating that the government was
    “required to prove only a minimal, potential effect on
    interstate commerce”).
    Moreover, any error would have been harmless. It is clear
    beyond a reasonable doubt that a rational jury could have
    found Luong guilty because, as stated above, Luong clearly
    affected interstate commerce by robbing his victim as part of
    UNITED STATES V. LUONG                     23
    a commercial transaction facilitated by a website that forms
    an interstate market for used cars.
    V. Prosecutorial Misconduct
    The court reviews for abuse of discretion preserved
    claims of prosecutorial misconduct, applying a harmless error
    analysis. United States v. Del Toro-Barboza, 
    673 F.3d 1136
    ,
    1150 (9th Cir. 2012). This requires viewing the “challenged
    conduct ‘in the entire context of the trial,’ and revers[ing]
    ‘only if it appears more probable than not that prosecutorial
    misconduct materially affected the fairness of the trial.’”
    United States v. Alcantara-Castillo, 
    788 F.3d 1186
    , 1190–91
    (9th Cir. 2015) (quoting United States v. Ruiz, 
    710 F.3d 1077
    ,
    1082 (9th Cir. 2013)). Where the defendant failed to object
    to a statement at trial, the court reviews for plain error.
    Id. at 1190.
    On plain error review, reversal is warranted only if
    “(1) there was error; (2) it was plain; (3) it affected the
    defendant’s substantial rights; and (4) ‘viewed in the context
    of the entire trial, the impropriety seriously affected the
    fairness, integrity, or public reputation of judicial
    proceedings.’”
    Id. at 1191
    (quoting United States v. Combs,
    
    379 F.3d 564
    , 568 (9th Cir. 2004)). While there is no
    question that the tenor of the parties’ arguments was tense
    and accusatory, we ultimately conclude that nothing in them
    requires reversal.
    Luong first argues that the government committed
    misconduct by misstating the law; specifically, he contends
    that the prosecutor repeatedly argued to the jury that Luong’s
    robbery had an effect on interstate commerce based upon “the
    use of interstate commerce.” This issue was preserved, and
    thus we review whether the district court abused its discretion
    24                UNITED STATES V. LUONG
    in finding that any alleged error was cured by its instructions.
    See Del 
    Toro-Barboza, 673 F.3d at 1150
    .
    Because we do not reach whether the mere use of the
    Internet, no matter how slight, is sufficient to satisfy the
    Hobbs Act jurisdictional nexus, we assume the defendant is
    correct that the government incorrectly stated the law. Even
    so, the district court did not abuse its discretion in concluding
    that this did not rise to the level of incurable misconduct. The
    district court and the government admonished the jury several
    times that the jury instructions controlled over the
    government’s recitation of the law, and the jury instructions
    clearly stated that a conviction required the jury to find that
    Luong’s robbery had affected interstate commerce. As
    discussed above, there was considerable evidence that
    Craigslist formed an interstate market for used cars and that
    Luong affected interstate commerce by robbing his victim as
    part of a commercial transaction facilitated by Craigslist.
    Therefore, the prosecutor’s statements when considered “in
    the entire context of the trial” amounted to harmless error.
    See 
    Alcantara-Castillo, 788 F.3d at 1190
    (quoting 
    Ruiz, 710 F.3d at 1082
    ).
    Luong next attacks the prosecutor’s statements that the
    jury needed to do its “job” or “duty” and convict the
    defendant, as well as the prosecutor’s accusations that
    defense counsel had asked the jury to disobey the instruction
    and “[f]eign[ed] re[v]erence for the Constitution.” The
    district court’s denial of the defendant’s motion for new trial
    is reviewed for plain error because defense counsel did not
    contemporaneously object. See United States v. Sanchez,
    
    176 F.3d 1214
    , 1218 (9th Cir. 1999).
    UNITED STATES V. LUONG                      25
    This court has held that it is “improper for the prosecutor
    to state that the duty of the jury is to find the defendant
    guilty.”
    Id. at 1224–25
    (citing United States v. Polizzi,
    
    801 F.2d 1543
    , 1558 (9th Cir. 1986)); see also United States
    v. Young, 
    470 U.S. 1
    , 18, 20 (1985) (stating that the
    prosecutor erred in trying “to exhort the jury to ‘do its job’
    [because] that kind of pressure, whether by the prosecutor or
    defense counsel, has no place in the administration of
    criminal justice,” but ultimately concluding that, “reviewed
    in context,” the statements did not undermine fundamental
    fairness and “contribute to a miscarriage of justice”). The
    court, in Sanchez, observed that
    [t]here is perhaps a fine line between a proper
    and improper “do your duty” argument. It is
    probably appropriate for a prosecutor to argue
    to the jury that “if you find that every element
    of the crime has been proved beyond a
    reasonable doubt, then, in accord with your
    sworn duty to follow the law and apply it to
    the evidence, you are obligated to convict,
    regardless of sympathy or other sentiments
    that might incline you otherwise.”
    Id. at 1225.
    In Sanchez, the court concluded that the
    prosecutor’s argument had been improper in part because the
    prosecutor “did not tell the jury that it had a duty to find the
    defendant guilty only if every element of the crime had been
    proven beyond a reasonable doubt. Nor did he remind the
    jury that it had the duty to acquit Sanchez if it had a
    reasonable doubt regarding his guilt.” Id.; see also United
    States v. Gomez, 
    725 F.3d 1121
    , 1131 (9th Cir. 2013)
    (holding prosecutor’s statement was proper where prosecutor
    argued that “if the jury finds that the prosecution has met its
    26               UNITED STATES V. LUONG
    burden of proving the elements beyond a reasonable doubt,
    then it is the jury’s duty to convict” (emphasis in original)).
    The government’s statements plainly were improper: the
    government impermissibly attacked the credibility of defense
    counsel and told the jury that it could only carry out its duty
    by siding with the government. But, in the context of both
    attorneys’ arguments, the district court’s directive to follow
    the instructions, the jury instructions themselves, and the
    government’s statements at other times during the argument
    that the jury must weigh all of the evidence to reach its
    conclusion, these statements do not warrant reversal. See
    United States v. Frederick, 
    78 F.3d 1370
    , 1380 (9th Cir.
    1996) (disapproving of a prosecutor’s statements maligning
    defense counsel to the jury, but concluding that those
    comments did not “cross[] the line sufficiently to warrant”
    reversal).
    VI.     Felon in Possession Conviction under Section
    922(g)(1)
    After this case was argued and submitted, the Supreme
    Court decided Rehaif v. United States, in which it held that,
    in order to convict a defendant under 18 U.S.C. § 922(g), the
    government “must prove both that the defendant knew he
    possessed a firearm and that he knew he belonged to the
    relevant category of persons barred from possessing a
    firearm.” 
    139 S. Ct. 2191
    , 2200 (2019) (emphasis added).
    We granted Luong leave to file supplemental briefing to
    address the impact of Rehaif on his conviction on count 3 for
    being a felon in possession of a firearm pursuant to 18 U.S.C.
    § 922(g)(1).
    UNITED STATES V. LUONG                      27
    The following is undisputed: the indictment did not
    charge the requisite knowledge of status; Luong stipulated to
    the fact that he had, at the time of the robbery, been convicted
    of a crime punishable by imprisonment for a term exceeding
    one year; and the government did not present evidence to the
    jury that Luong knew he was a convicted felon when he
    possessed the firearm. Luong argues that the district court’s
    failure to instruct the jury that knowledge of his felon status
    was an element of the felon-in-possession count constituted
    plain error. The government concedes that, with respect to
    this knowledge-of-status element, an obvious error occurred,
    but it argues that such error did not affect Luong’s substantial
    rights, nor does it seriously affect the fairness, integrity, or
    public reputation of the judicial proceedings.
    The court applies plain error review to a sufficiency-of-
    the-evidence argument that was not raised before the district
    court. See United States v. Benamor, 
    937 F.3d 1182
    , 1188
    (9th Cir. 2019), cert. denied, 
    140 S. Ct. 818
    (2020) (citing
    United States v. Flyer, 
    633 F.3d 911
    , 917 (9th Cir. 2011)).
    To establish plain error, a defendant must demonstrate “(1) an
    error (2) that was obvious and (3) that affected the
    defendant’s substantial rights and (4) that seriously affected
    the fairness, integrity, or public reputation of judicial
    proceedings[.]”
    Id. (citing United
    States v. Olano, 
    507 U.S. 725
    , 734, 736 (1993)).
    It was clear error, under Rehaif, for the jury to not have
    been instructed that knowledge of status was an element of
    count 3. See Henderson v. United States, 
    568 U.S. 266
    , 272
    (2013) (“Even where a new rule of law is at issue, Rule 52(b)
    does not give a court of appeals authority to overlook a
    failure to object unless an error not only ‘affect[s] substantial
    rights’ but also ‘seriously affect[s] the fairness, integrity or
    28               UNITED STATES V. LUONG
    public reputation of judicial proceedings.’” (quoting 
    Olano, 507 U.S. at 732
    )); see also Griffith v. Kentucky, 
    479 U.S. 314
    ,
    321 & n.6 (1987) (holding that Supreme Court decisions
    govern criminal cases pending on direct appeal). Still,
    however, Luong cannot satisfy the third and fourth
    requirements of the plain error test. For an error to affect a
    defendant’s substantial rights, in the ordinary case, the
    defendant must demonstrate “‘a reasonable probability that,
    but for the error,’ the outcome of the proceeding would have
    been different[.]” Molina-Martinez v. United States, 136 S.
    Ct. 1338, 1343 (2016) (quoting United States v. Dominguez
    Benitez, 
    542 U.S. 74
    , 76, 82 (2004)).
    Luong had at least six prior felony convictions at the time
    he possessed the charged firearm, four of which resulted in
    prison sentences exceeding one year. In total, these
    convictions resulted in Luong being incarcerated for more
    than a decade. In light of this, while clear error did occur
    here, we conclude that, even if the district court had
    instructed the jury on the knowledge-of-status element, there
    is no reasonable probability that the jury would have reached
    a different verdict on count 3. See 
    Rehaif, 139 S. Ct. at 2198
    (noting that it would not be burdensome for the government
    to prove a defendant’s knowledge of status where
    “knowledge can be inferred from circumstantial evidence”
    (quoting United States v. Staples, 
    511 U.S. 600
    , 615 n.11
    (1994))). For this reason, the error did not affect Luong’s
    substantial rights, nor the fairness, integrity, or public
    reputation of the first trial. See 
    Benamor, 937 F.3d at 1189
    (holding plain error did not affect the defendant’s substantial
    rights, nor the fairness, integrity, or public reputation of the
    trial, where the defendant had seven prior convictions: three
    resulting in sentences of more than one year of imprisonment,
    including one for being a felon in possession of a firearm, and
    UNITED STATES V. LUONG                     29
    one for being a felon in possession of ammunition); see also
    United States v. Johnson, No. 17-10252, 
    2020 WL 3458969
    ,
    at *5 (9th Cir. June 25, 2020) (holding that uncontroverted
    evidence of felony convictions for which a defendant served
    sentences exceeding one year “will ordinarily preclude a
    defendant from satisfying the fourth prong of plain-error
    review when challenging the sufficiency of the evidence that
    he knew of his status as a convicted felon”). Thus, we affirm
    Luong’s conviction on count 3.
    VII.   Hobbs Act Robbery as a Predicate Crime of
    Violence under Section 924(c)
    The court reviews “de novo whether a criminal conviction
    is a crime of violence under § 924(c)(3).” United States v.
    Dominguez, 
    954 F.3d 1251
    , 1256 (9th Cir. 2020) (citing
    United States v. Begay, 
    934 F.3d 1033
    , 1037 (9th Cir. 2019)).
    In his penultimate challenge on appeal, Luong argues that
    the district court erred in denying his motion to dismiss count
    2 of the indictment, which charged Luong with brandishing
    a firearm during and in relation to a crime of violence in
    violation of 18 U.S.C. § 924(c)(1)(A)(ii). As the basis for his
    challenge, Luong argues that Hobbs Act robbery does not
    constitute a predicate crime of violence as defined in
    § 924(c)(3)(A). During the pendency of this appeal, another
    panel of this court “reaffirm[ed] that Hobbs Act robbery is a
    crime of violence under 18 U.S.C. § 924(c)(3)(A),”
    
    Dominguez, 954 F.3d at 1261
    , thus foreclosing Luong’s
    argument. For the same reasons as those set forth in
    Dominguez, we hold Hobbs Act robbery constitutes a
    predicate crime of violence, and therefore affirm Luong’s
    conviction on count 2.
    30               UNITED STATES V. LUONG
    VIII. Credit for Acceptance of Responsibility
    In his final challenge on appeal, Luong argues that the
    district court erred in declining to give him a two-level
    downward adjustment for acceptance of responsibility under
    the United States Sentencing Guidelines (“U.S. Sentencing
    Guidelines” or “U.S.S.G.”). “We review de novo whether the
    district court misapprehended the law with respect to the
    acceptance of responsibility reduction.” United States v.
    Garrido, 
    596 F.3d 613
    , 617 (9th Cir. 2010) (quoting United
    States v. Cortes, 
    299 F.3d 1030
    , 1037 (9th Cir. 2002)).
    “Whether or not the defendant has accepted responsibility for
    his crime is a factual finding that we review for clear error.”
    Id. (citing United
    States v. McKinney, 
    15 F.3d 849
    , 852 n.6
    (9th Cir. 1994)).
    The U.S. Sentencing Guidelines provide for a two-level
    decrease to a defendant’s offense level where the defendant
    “clearly demonstrates acceptance of responsibility for his
    offense[.]” U.S.S.G. § 3E1.1(a). A defendant’s decision to
    go to trial does not necessarily foreclose him from receiving
    this offense-level decrease. U.S.S.G. § 3E1.1 cmt. 2; see also
    
    McKinney, 15 F.3d at 854
    (vacating sentence and concluding
    the defendant was eligible for a reduction where he confessed
    and assisted police upon apprehension, tried to plead guilty
    but was rebuffed, and went to trial on conspiracy charge).
    The comments to § 3E1.1(a) state, in relevant part:
    In rare situations a defendant may clearly
    demonstrate an acceptance of responsibility
    for his criminal conduct even though he
    exercises his constitutional right to a trial.
    This may occur, for example, where a
    defendant goes to trial to assert and preserve
    UNITED STATES V. LUONG                     31
    issues that do not relate to factual guilt (e.g.,
    to make a constitutional challenge to a statute
    or a challenge to the applicability of a statute
    to his conduct).
    U.S.S.G. § 3E1.1 cmt. 2. At bottom, the district court must
    determine whether a defendant “manifest[ed] a genuine
    acceptance of responsibility for his actions.” 
    Cortes, 299 F.3d at 1038
    (quoting 
    McKinney, 15 F.3d at 852
    ). “If [the
    defendant’s] statements and conduct made it clear that his
    contrition was sincere, he [is] entitled to the reduction.”
    Id. The focus
    of this inquiry must be “on the defendant’s
    personal contrition, rather than on his exercise of his
    constitutional rights” in order to “best serve[] the purposes of
    the acceptance of responsibility reduction.” 
    McKinney, 15 F.3d at 853
    . And just as the U.S. Sentencing Guidelines
    do not aim to “penalize the exercise of the constitutional right
    to go to trial[,]”
    id. at 852,
    the Guidelines do not set out to
    penalize a defendant for preventing constitutionally infirm or
    otherwise inadmissible evidence from reaching the jury. See
    United States v. Ochoa-Gaytan, 
    265 F.3d 837
    , 844 (9th Cir.
    2001) (holding that the district court erred in denying
    acceptance of responsibility adjustment on the basis that the
    defendant moved to suppress a constitutionally infirm
    statement).
    At trial, Luong admitted his factual guilt—specifically,
    that he used a gun to rob Montellano—but he moved to
    exclude evidence supporting the government’s interstate-
    commerce theory. To illustrate, Luong objected to the
    testimony of Patrice Alexander-Lee, a product manager at
    STAR Networks, on the grounds of personal knowledge, lack
    of expert notice, and hearsay, as well as to the testimony of
    Jeffrey Jackson, a Bank of America operations analyst and
    32               UNITED STATES V. LUONG
    custodian of records, on the basis of lack of personal
    knowledge. The district court allowed Alexander-Lee and
    Jackson to testify but later struck portions of Jackson’s
    testimony. Luong further objected to, on hearsay and
    Confrontation Clause grounds, the testimony of William
    Powell, Craigslist’s director of government and law
    enforcement relations, regarding information he had learned
    from coworkers at Craigslist. The district court agreed the
    testimony would be hearsay, and ruled that “the only server-
    related information to which he may testify is his knowledge
    of the location of the servers.” In response to this ruling, the
    government summoned to testify Dallas Wisehaupt, a
    Craigslist system manager, that same day. The district court
    overruled an objection that it was expert testimony for which
    Luong had not been provided proper notice and time to
    prepare.
    At the sentencing hearing, the district court acknowledged
    that Luong’s decision to go to trial was not reason in itself to
    deny the two-level decrease. The district court stated that
    Luong had challenged only the jurisdictional element of the
    Hobbs Act, and commented on counsel’s zealous
    performance in challenging that single element. The district
    court noted that, while Luong’s challenges to the
    government’s evidence on the interstate-commerce element
    constituted a “legitimate strategy,” they were not consistent
    with contrition. Making no other findings as to the
    defendant’s contrition, the district court concluded that, under
    these circumstances, a reduction for acceptance of
    responsibility was not warranted.
    The district court erred, Luong contends, because his
    evidentiary objections went only to whether the interstate-
    commerce nexus was satisfied, he presented no evidence in
    UNITED STATES V. LUONG                       33
    his defense, and his cross-examination was confined to
    challenging the interstate-commerce element and any
    suggestion that he was dangerous or violent. The government
    counters that Luong fought to exclude a range of government
    evidence, including cell phone evidence, photo line-up
    evidence, other-acts and prior-conviction evidence, Craigslist
    evidence, and testimony from Bank of America, STAR
    Network, and Craigslist employees, among others.
    The commentary to the U.S. Sentencing Guidelines
    explicitly provides that a defendant may admit factual guilt
    but go to trial to “challenge . . . the applicability of a statute
    to his conduct.” U.S.S.G. § 3E1.1(a) cmt. 2. Here, Luong
    admitted factual guilt, but proceeded to trial to assert that his
    offense conduct did not fall within the scope of the Hobbs
    Act’s jurisdictional nexus.           Challenging the federal
    government’s jurisdiction to prosecute the alleged offense
    conduct is not inconsistent with contrition. Nor is a
    defendant foreclosed from receiving credit for acceptance of
    responsibility because his attorney made good-faith
    challenges at trial to evidence going to that question. Insofar
    as the district court declined to give the adjustment based on
    such challenges by Luong’s counsel, it erred as a matter of
    law.
    To hold otherwise would be to mandate that defense
    counsel sit on her hands while the government proffers
    affidavits in lieu of live testimony, or lay witnesses rather
    than qualified experts to provide expert opinions, or surprise
    witnesses a la Perry Mason. Here, Luong’s evidentiary
    challenges, some of which were sustained and resulted in
    stricken testimony, were part and parcel of Luong’s challenge
    to the interstate-commerce nexus. See United States v Rojas-
    Flores, 
    384 F.3d 775
    , 780–81 (9th Cir. 2004) (holding that
    34                 UNITED STATES V. LUONG
    the district court erred in denying adjustment for acceptance
    of responsibility where the defendant went to trial to
    challenge the applicability of the statute of offense instead of
    his factual guilt, and the defendant cross-examined
    witnesses); United States v. Ing, 
    70 F.3d 553
    , 556 (9th Cir.
    1995) (vacating sentence and remanding case for
    resentencing, noting that “an entrapment defense is not
    necessarily incompatible with acceptance of responsibility”);
    
    McKinney, 15 F.3d at 852
    (noting that a defense that relied on
    cross-examination and presented no affirmative defense “is
    hardly the kind of defense that refutes the strong inference
    that [the defendant] accepted responsibility”).
    While the government also takes issue with Luong’s
    counsel’s use of the word “innocence” during closing
    arguments and Luong’s failure to demonstrate, in the
    government’s view, meaningful contrition, these arguments
    are non-starters. Luong’s attorney argued that he was
    innocent under the statute because the interstate-commerce
    nexus was not satisfied. See, e.g., ER 364 (“He is innocent of
    the charges in Counts One and Two because this robbery did
    not affect or potentially affect interstate commerce . . . .
    [T]he Defense is not here to deny that a robbery occurred; to
    deny the experience of the victim in this case, Mr.
    Montellano. Nobody should have to experience being
    robbed. But what happened was not a federal crime on
    February 15th, 2015.”). But as discussed above, this is not
    inconsistent, as a matter of law, with contrition. And while
    the district court clearly would have acted according to law
    by denying the adjustment for the defendant’s lack of
    contrition, in light of his failure to allocute and his brief letter
    of contrition, the district court did not state that it relied on
    these factors. See, e.g., United States v. McKittrick, 
    142 F.3d 1170
    , 1178 (9th Cir. 1998) (concluding that the defendant’s
    UNITED STATES V. LUONG                    35
    challenge to regulation’s intent requirement did not foreclose
    an adjustment for acceptance of responsibility and,
    accordingly, vacating and remanding case to determine
    whether the denial was based on an impermissible ground).
    We vacate Luong’s sentence and remand for resentencing,
    leaving it for the district court to make a factual finding on
    contrition in the first instance.
    CONCLUSION
    For the foregoing reasons, the judgment of the district
    court is AFFIRMED in part and VACATED in part. The
    case is REMANDED to the district court for further
    proceedings consistent with this opinion.
