    Before SMITH, Chief Judge, LOKEN and GRUENDER, Circuit Judges.
    ____________
    GRUENDER, Circuit Judge.
    Kelvin Baez was indicted for conspiracy to distribute methamphetamine, 
    21 U.S.C. §§ 841
    (a)(1), (b)(1)(A), 846, conspiracy to possess firearms in furtherance of
    drug trafficking, 
    18 U.S.C. § 924
    (c), and possession of methamphetamine with
    intent to distribute, 
    21 U.S.C. § 841
    (a)(1), (b)(1)(A). After a jury found Baez guilty
    on all three counts, the district court 1 sentenced him to 168 months’ imprisonment.
    Baez appeals, raising several challenges to his conviction and sentence. We affirm.
    I.
    From September 2016 to May 2017, Baez distributed methamphetamine as
    part of a drug-trafficking conspiracy in Minnesota. On May 5, 2017, Officer Jacob
    Gruber stopped another member of the conspiracy, Rodolfo Anguiano, for expired
    license plates. Officer Gruber arrested Anguiano upon seeing numerous dryer sheets
    on the floor of his car as well as a fake Drug Enforcement Administration (“DEA”)
    badge and more than ten credit cards in his wallet. A search of the car revealed large
    wads of cash and additional credit cards in different names.
    Joined by two other officers, Officer Gruber proceeded to the hotel suite
    where Anguiano was staying. One of the officers knocked on the door. Baez’s wife,
    Zyaira Gavino, opened the door and waved in the officers when they requested
    permission to enter. Baez was sitting in the front room of the suite next to Chevrolet
    keys and a methamphetamine pipe. The officers asked Gavino’s consent to search
    “the room,” which she granted, gesturing to some bags in the front room. In a
    backpack between Gavino and Baez, the officers found a Chevrolet Equinox owner’s
    manual. After searching the front room of the suite, the officers proceeded through
    an open door to the back room and saw a locked armoire that appeared to be under
    cell-phone video surveillance. The officers called for a canine unit, which alerted at
    the armoire and at an Equinox in the hotel parking lot that flashed its lights when an
    officer pressed the unlock and lock buttons on the Chevrolet keys. Officer Gruber
    searched the rest of the back room and discovered two large bags of
    methamphetamine hidden under a sink.

    The Honorable Ann D. Montgomery, United States District Judge for the
    District of Minnesota.
    -2-
    At that point, Officer Gruber arrested Gavino and Baez. The officers obtained
    a warrant to search the hotel suite and the Equinox. In the armoire, they discovered
    methamphetamine and a firearm.               In the Equinox, they discovered
    methamphetamine, another firearm, and a safe with ammunition as well as receipts
    in Baez’s name. The next day, Baez made incriminating statements while in
    custody.
    Baez and some of his coconspirators, including Anguiano, were indicted over
    the next several months. After pleading guilty, Anguiano unsuccessfully appealed
    the district court’s denial of his motion to suppress evidence obtained from the
    searches of the armoire and the Equinox. See United States v. Anguiano, 
    934 F.3d 871
     (8th Cir. 2019). The district court also denied Baez’s motions to suppress the
    evidence found in the back room, the evidence found in the safe in the Equinox, and
    the incriminating statements that he made while in custody.
    Baez was the only defendant among the conspirators not to plead guilty. At
    trial, he advanced an “innocent-intent” defense, claiming that he was infiltrating the
    drug-trafficking conspiracy with the intention of assisting law enforcement. To
    bolster this defense, Baez sought to introduce evidence regarding his mental health
    and a potential informant with whom he had been acquainted when he lived in North
    Carolina. In addition, Baez moved to compel the Government to disclose
    information about the potential informant pursuant to Brady v. Maryland, 
    373 U.S. 83
     (1963). The district court excluded the evidence that Baez sought to introduce
    and only partially granted his Brady motion. The district court declined Baez’s
    request to instruct the jury that it would “negate[] the specific intent required by the
    charges” if Baez intended to “assist ongoing federal investigations” and believed
    that “his actions were not criminal.”
    The jury convicted Baez on all three counts charged in the indictment. At
    sentencing, the district court concluded that Baez’s criminal history was overstated
    and departed downward from the guidelines, settling on a criminal-history category
    of III instead of a criminal-history category of V. Because Baez’s offense level was
    -3-
    40, this resulted in an advisory sentencing guidelines range of 360 months’ to life
    imprisonment. The district court then proceeded to vary downward by more than
    fifty percent, sentencing Baez to 168 months’ imprisonment.
    Baez appeals, challenging the denial of his suppression motions, the district
    court’s failure to instruct the jury on his “innocent-intent” defense, the exclusion of
    the evidence related to his “innocent-intent” defense, the partial denial of his Brady
    motion, and the substantive reasonableness of his sentence.
    II.
    First, Baez argues that the district court erred in denying his motions to
    suppress the evidence found in the back room of the hotel suite, the evidence found
    in the safe in the Equinox, and the incriminating statements that he made while in
    custody. When considering the denial of a Fourth Amendment suppression motion,
    “we review the district court’s conclusions of law de novo and its factual findings
    for clear error.” United States v. Molsbarger, 
    551 F.3d 809
    , 811 (8th Cir. 2009).
    A.
    We begin with Baez’s challenges to the admission of the evidence found in
    the back room and in the safe in the Equinox.
    1.
    With limited exceptions, evidence acquired during, or as a consequence of, a
    search that violates the Fourth Amendment is inadmissible. Utah v. Strieff, 579 U.S.
    ---, 
    136 S. Ct. 2056
    , 2061 (2016). The two exceptions relevant here are the
    independent-source doctrine and the inevitable-discovery doctrine. Neither doctrine
    applies unless the evidence would have been acquired by lawful means had the
    unlawful search not occurred. See Nix v. Williams, 
    467 U.S. 431
    , 443-44 (1984)
    (explaining that neither doctrine puts the prosecution “in a better position than it
    -4-
    would have been in if no illegality had transpired”). The independent-source
    doctrine applies if the evidence both would have been acquired by lawful means had
    the unlawful search not occurred and in fact was acquired (or reacquired) by these
    lawful means. The inevitable-discovery doctrine, on the other hand, applies if the
    evidence would have been acquired by lawful means had the unlawful search not
    occurred but in fact was not acquired (or reacquired) by these lawful means. See
    Murray v. United States, 
    487 U.S. 533
    , 539 (1988) (noting that the inevitable-
    discovery doctrine applied in Nix because a lawful search “would have found” the
    evidence “had [the search] not been aborted” when the evidence was acquired
    unlawfully, but the independent-source doctrine would have applied “if the search
    had continued and had in fact found” the evidence).
    Although the distinction between the independent-source and inevitable-
    discovery doctrines is not sharp, see, e.g., United States v. Johnson, 
    380 F.3d 1013
    ,
    1014 (7th Cir. 2004) (expressing uncertainty regarding “which [doctrine] rules this
    case”), where exactly one draws the line between the two doctrines is unimportant.
    Underlying both doctrines is the principle that, “while the government should not
    profit from its illegal activity, neither should it be placed in a worse position than it
    would otherwise have occupied.” Murray, 
    487 U.S. at 542
    ; see also Nix, 
    467 U.S. at 443-44
     (explaining that the point of both doctrines is to put the police “in the same
    . . . position that they would have been in if no police error or misconduct had
    occurred”). Provided that the evidence would have been acquired lawfully if the
    unlawful search had not occurred, admitting the evidence puts the government in the
    same position that it would have occupied if the unlawful search had not occurred.
    This is true regardless whether the evidence in fact was (re)acquired lawfully—and
    thus whether the appropriate exception to invoke is the independent-source doctrine
    rather than the inevitable-discovery doctrine. See Murray, 
    487 U.S. at 541-42
    (explaining that admissibility does not turn on the “metaphysical” question whether
    it is possible for officers who retain evidence after seizing it unlawfully to “reseize[]”
    it lawfully).
    -5-
    One way for police to acquire evidence lawfully is pursuant to a valid search
    warrant. See, e.g., Horton v. California, 
    496 U.S. 128
    , 139 (1990). To determine
    whether evidence within the scope of a valid warrant would have been acquired had
    a prior unlawful search not occurred, we ask whether (1) law enforcement “would
    have sought a warrant even if the [unlawful] search had not occurred,” and (2) “the
    warrant was supported by probable cause even without information gained from the
    [unlawful] search.” Anguiano, 934 F.3d at 874.
    Here, the officers ultimately obtained a warrant to search the entire hotel suite
    and the Equinox. Crediting Officer Gruber’s testimony, the district court found that
    the officers would have halted their search and sought a warrant had they thought
    that they lacked valid consent from Gavino to search the entire suite. United States
    v. Anguiano, No. 17-135(1) ADM/DTS, 
    2019 WL 2443540
    , at *5-6 (D. Minn. June
    11, 2019). We affirmed this finding in Anguiano, 934 F.3d at 874, and we are bound
    by that precedent here, see Mader v. United States, 
    654 F.3d 794
    , 800 (8th Cir. 2011)
    (en banc) (“[O]ne panel is bound by the decision of a prior panel.”). The district
    court also found that the warrant was supported by probable cause even without the
    information gained from the allegedly unlawful search of the back room. United
    States v. Anguiano, No. 17-135 ADM/DTS, 
    2017 WL 6501840
    , at *10 (D. Minn.
    Dec. 19, 2017). Again, we affirmed this finding in Anguiano, 934 F.3d at 875, and
    we are bound by that precedent here, see Mader, 654 F.3d at 800. Even assuming
    the initial search of the back room was unlawful, then, any evidence that fell within
    the scope of the warrant was admissible. And both the evidence found in the back
    room and the evidence found in the safe in the Equinox fell within the scope of the
    warrant. See United States v. Darr, 
    661 F.3d 375
    , 379 (8th Cir. 2011) (explaining
    that a warrant to search a bedroom authorized a search of containers in the bedroom).
    Therefore, both the evidence found in the back room and the evidence found in the
    safe in the Equinox were admissible.
    It is true that Baez is not bringing exactly the same challenge that Anguiano
    brought. Anguiano appealed only the admission of the evidence found in the armoire
    and the evidence found in the Equinox, which not only would have been but in fact
    -6-
    were acquired lawfully, during the later search. See Anguiano, 934 F.3d at 874.
    Here, Baez also challenges the evidence found under the sink. Because the officers
    had already uncovered this evidence during the earlier search, it is a stretch to say
    that it not only would have been but was (re)acquired lawfully. But this difference
    is relevant only to which doctrine accounts for the admissibility of the respective
    pieces of evidence. In Anguiano, we invoked the independent-source doctrine. See
    id. at 874-75. Here, at least with respect to the evidence found under the sink, the
    inevitable-discovery doctrine appears more appropriate. The bottom line is that,
    whichever doctrine applies, the evidence found under the sink, the evidence found
    in the armoire, and the evidence found in the Equinox (including the evidence found
    in the safe) were all admissible.
    2.
    Before considering Baez’s objections to our analysis, we address whether our
    reliance on the inevitable-discovery doctrine is consistent with circuit precedent. We
    conclude that it is.
    Our caselaw on the inevitable-discovery doctrine divides into two strands.
    The first strand aligns with the view that the Supreme Court has endorsed since Nix.
    On this view, in order for evidence acquired unlawfully and not reacquired lawfully
    to be admissible under the inevitable-discovery doctrine, it is sufficient that the
    evidence would have been acquired lawfully but for the constitutional violation. See
    Nix, 
    467 U.S. at 444
     (holding that “evidence that would inevitably have been
    discovered” is admissible because excluding it would “put the government in a
    worse position” than “if no misconduct had taken place”); Hudson v. Michigan, 
    547 U.S. 586
    , 592 (2006) (reiterating that “a necessary . . . condition for suppression” is
    “that a constitutional violation was a ‘but-for’ cause of obtaining [the] evidence”).
    From our adoption of the inevitable-discovery doctrine in United States v. Apker,
    
    705 F.2d 293
     (8th Cir.), rev’d in part on other grounds en banc, 
    724 F.2d 633
     (8th
    Cir. 1983), until our decision in United States v. Conner, 
    127 F.3d 663
     (8th Cir.
    1997), we articulated the doctrine in a way that is consistent with this view. See,
    -7-
    e.g., Apker, 705 F.2d at 306 (holding that the inevitable-discovery doctrine “allows
    illegally obtained evidence to be admitted if it would have been discovered in the
    course of a proper investigation”); United States v. Durant, 
    730 F.2d 1180
    , 1185 (8th
    Cir. 1984) (holding that the inevitable-discovery doctrine applies “when the
    evidence would have been inevitably discovered absent the illegal conduct”);
    Hamilton v. Nix, 
    809 F.2d 463
    , 465-66 (8th Cir. 1987) (en banc) (explaining that
    evidence is admissible under the inevitable-discovery doctrine if “it inevitably would
    have been discovered by lawful means” and stating that “there is no reason to
    exclude . . . evidence” if “police misconduct is not even a ‘but for’ cause of its
    discovery”); United States v. Dickson, 
    64 F.3d 409
    , 410 (8th Cir. 1995) (quoting
    Hamilton).
    In Conner, however, we held that the inevitable-discovery doctrine applies
    only if the government shows not only (1) “that the evidence would have been
    discovered by lawful means in the absence of police misconduct” but also (2) “that
    the government was actively pursuing a substantial, alternative line of investigation
    at the time of the constitutional violation.” 
    127 F.3d at 667
    ; cf. United States v.
    Thomas, 
    524 F.3d 855
    , 860-62 (8th Cir. 2008) (Colloton, J., concurring) (pointing
    out the differences between the Supreme Court’s approach in Nix and our approach
    in Conner).
    Since Conner, our practice has been inconsistent. In some cases, we have
    repeated Conner’s two-condition test. See, e.g., United States v. Glenn, 
    152 F.3d 1047
    , 1049 (8th Cir. 1998) (citing Conner); Thomas, 
    524 F.3d at
    858 (citing Glenn);
    United States v. Munoz, 
    590 F.3d 916
    , 923 (8th Cir. 2010) (citing Thomas). In other
    cases, we have repeated the one-condition test from Nix and our earlier caselaw. See,
    e.g., United States v. Reinholz, 
    245 F.3d 765
    , 779 (8th Cir. 2001) (citing Eighth
    Circuit caselaw prior to Conner); United States v. Craddock, 
    841 F.3d 756
    , 760 (8th
    Cir. 2016) (citing Nix); United States v. Sallis, 
    920 F.3d 577
    , 582-83 (8th Cir. 2019)
    (citing Nix). In one case, we even applied the inevitable-discovery doctrine despite
    acknowledging that there was no contemporaneous alternative line of investigation.
    See United States v. Chandler, 
    197 F.3d 1198
    , 1201 (8th Cir. 1999).
    -8-
    The uncertainty in our caselaw regarding the inevitable-discovery doctrine
    does not stand in the way of our application of that doctrine here. We already
    explained in Section II.A.1 why the evidence found under the sink satisfies the test
    from Nix and our earlier caselaw. Therefore, our application of the inevitable-
    discovery doctrine here is proper unless Conner’s test is controlling. And even if
    Conner’s test is controlling, our application of the inevitable-discovery doctrine here
    is proper if Conner’s second condition is met. Because either possibility—that
    Conner is not controlling or that Conner’s second condition is met—would be
    sufficient to support our application of the inevitable-discovery doctrine here, we
    need not decide which is true. It is enough to conclude that at least one is true. And
    we know that at least one is true because, prior to Conner, we applied the inevitable-
    discovery doctrine in a case where it was less plausible than it is here that a
    contemporaneous alternative line of investigation was present.
    That case is Durant, 
    730 F.2d 1180
    . In Durant, the defendant—charged with
    bank robbery—challenged the admission of evidence that he drove a blue
    Oldsmobile, which the police had acquired by unlawfully interrogating him while
    arresting him for an unrelated offense. 
    Id. at 1184-85
    . The police did not realize the
    significance of the car until “[l]ater,” “when [the defendant] was linked to the bank
    robbery.” 
    Id.
     We held that the evidence was admissible under the inevitable-
    discovery doctrine because, if the police had not known already that the defendant
    drove a blue Oldsmobile, then they would have found out by tracing the driver’s
    license and traffic citation that they had obtained from the defendant when he was
    arrested. 
    Id. at 1185
    .
    It is more plausible that a contemporaneous alternative line of investigation
    was present here than in Durant. In United States v. Hammons, we held that it was
    enough to constitute “actively pursuing a substantial, alternative line of
    investigation” for officers to have in mind “an alternative plan” that they would have
    executed if the constitutional violation had not occurred. 
    152 F.3d 1025
    , 1030 (8th
    Cir. 1998). Here, Officer Gruber conceded that it did not “occur” to him “to go and
    . . . get a warrant” when he and the other officers arrived at the suite, and it was not
    -9-
    until he “found the meth” under the sink that he “wanted to get the warrant.” But
    Officer Gruber also testified that he “understood that [getting a warrant] was an
    option” when he asked Gavino’s consent to search the room, and he “would have
    . . . called for a search warrant” had Gavino refused to consent. This implies that
    Officer Gruber was at least disposed to execute an alternative plan if Gavino refused
    to consent, even if he did not consciously have such a plan in mind. In Durant, by
    contrast, the officers had no reason to suspect that the defendant had participated in
    a robbery involving a blue Oldsmobile when they arrested him. Hence, there is
    nothing to indicate that they were disposed to trace the driver’s license and traffic
    citation in search of a blue Oldsmobile if the defendant refused to answer their
    questions—much less that they consciously had such a plan in mind. See Durant,
    
    730 F.2d at 1185
     (“[The defendant’s] connection to the blue Oldsmobile would have
    been inevitably discovered once the officers became aware of [his] alleged
    participation in the bank robbery.” (emphasis added)).
    The fact that it is more plausible that a contemporaneous alternative line of
    investigation was present here than in Durant shows that either Conner’s second
    condition is met here or else Conner is not controlling. On the one hand, if a
    contemporaneous alternative line of investigation was present in Durant, then a
    fortiori a contemporaneous alternative line of investigation was present here, too. In
    that case, our application of the inevitable-discovery doctrine here would be proper
    because Conner’s second condition would be met. On the other hand, if a
    contemporaneous alternative line of investigation was not present in Durant, which
    applied the inevitable-discovery doctrine anyway, then Conner’s second condition
    conflicts with prior-panel precedent. In that case, our application of the inevitable-
    discovery doctrine here would be proper because Conner would not be controlling.
    See Mader, 654 F.3d at 800 (holding that, in the event of “conflicting panel opinions,
    the earliest opinion must be followed”).2 In sum, whether because Conner’s second
    2
    Although Judge Colloton concluded in his Thomas concurrence that Conner
    was “governing precedent” despite his concerns with it, 
    524 F.3d at 862
    , we note
    that this remark was made before Mader was decided.
    -10-
    condition is met or because Conner is not controlling, circuit precedent supports our
    application of the inevitable-discovery doctrine here.
    3.
    Baez presents three additional objections to our analysis. First, he attacks the
    district court’s basis for denying his motion to suppress the evidence found under
    the sink during the initial search of the back room. The district court held that Baez
    lacked standing to challenge the legality of the search because he had no reasonable
    expectation of privacy in the back room. Even assuming Baez is correct that he had
    a reasonable expectation of privacy in the back room, however, the alternative basis
    for denying his suppression motion that we have articulated stands. Because “we
    can affirm the district court’s judgment on any ground that is supported by the
    record,” Taylor v. United States, 
    204 F.3d 828
    , 829 (8th Cir. 2000), we need not
    reach the question whether Baez had a reasonable expectation of privacy in the back
    room.
    Second, Baez disputes that the warrant would have been supported by
    probable cause even if the initial search of the back room had not occurred.
    According to Baez, “the methamphetamine found under the sink was included in the
    warrant [application] and most certainly influenced the judge’s decision [to issue the
    warrant].” We settled this dispute in Anguiano, where we recounted at length the
    evidence that “justified issuance of a warrant.” 934 F.3d at 875. Our conclusion
    there, that “probable cause [supported] issuance of the search warrant even without
    information gleaned from the initial search” of the back room, id., is binding here.
    See Mader, 654 F.3d at 800.
    Third, Baez argues that “the search [of the safe in the Equinox] was legal as
    to Anguiano but illegal as to Baez” because “the facts supporting probable cause for
    the warrant had nothing to do with Baez or his property and everything to do with
    Anguiano.” But the legality of a search pursuant to a valid warrant is not suspect-
    specific. See, e.g., Darr, 
    661 F.3d at 379
     (“Because the . . . warrant authorized the
    -11-
    search of the entire premises . . . , officers did not exceed its scope by searching [the
    defendant’s] bedroom, even though the warrant was issued based on information
    about activities of [the defendant’s father].”). Here, the warrant authorized the
    search of the entire Equinox, including containers inside it. This rendered the search
    of the safe legal without qualification, not merely “legal as to Anguiano.” Evidence
    from the search was therefore admissible not only against Anguiano but also against
    Baez.
    B.
    We now turn to Baez’s challenge to the district court’s denial of his motion to
    suppress the incriminating statements that he made while in custody. With limited
    exceptions, evidence acquired as a consequence of an arrest that violates the Fourth
    Amendment is inadmissible. See Strieff, 136 S. Ct. at 2061. Baez argues that his
    incriminating statements were acquired as a consequence of his unlawful arrest and
    that none of the exceptions to the exclusionary rule applies.
    Whether Baez’s warrantless arrest was lawful depends on whether the officers
    had probable cause to believe that he had committed a crime. See, e.g., Devenpeck
    v. Alford, 
    543 U.S. 146
    , 152 (2004). In Maryland v. Pringle, the Supreme Court
    held that officers have probable cause to believe that everyone present in a car in
    which drug trafficking was occurring was involved. 
    540 U.S. 366
    , 373-74 (2003).
    As the Court pointed out, it “would be unlikely” for anyone involved in drug
    trafficking “to admit an innocent person with the potential to furnish evidence
    against him” into the “relatively small” confines of a car. 
    Id. at 373
    . In United States
    v. Romero, the Sixth Circuit extended this reasoning to hotel rooms. 
    452 F.3d 610
    ,
    618 (6th Cir. 2006). “Like the enclosed space of the automobile in which the
    individuals were arrested in Pringle,” the court reasoned, “the relatively small and
    confined space of the hotel room supports the conclusion that it was reasonable for
    the officers to infer . . . that [everyone in the room] was involved in a common
    illegal-drug enterprise.” 
    Id.
    -12-
    Until today, we have not had occasion to join the Sixth Circuit in extending
    Pringle to hotel rooms or suites. In United States v. Cowan, however, we cited
    Romero when extending Pringle to apartments. See 
    674 F.3d 947
    , 954 (8th Cir.
    2012) (“As with the car in Pringle and the hotel room in Romero, the officers had
    probable cause to believe [the defendant], who was present in the apartment, was
    engaged in a common drug trafficking enterprise with the apartment’s occupants.”).
    A hotel suite is comparable to an apartment. Therefore, both Cowan’s reasoning and
    its citation to Romero support the proposition that officers have probable cause to
    believe that everyone present in a hotel suite in which drug trafficking was occurring
    was involved.
    Here, Baez was present in a hotel suite in which the police had probable cause
    to believe that drug trafficking was occurring. Even setting aside the evidence found
    in the back room, which Baez claims was inadmissible, but see supra Section II.A,
    the front room contained a methamphetamine pipe and keys to a car in which a
    canine unit had indicated drugs were present. In addition, the suite was reserved
    under the name of someone who had just been stopped in a car with a fake DEA
    badge, dryer sheets, numerous credit cards in different names, and large wads of
    cash. We conclude that the police had probable cause to believe that everyone
    present in the hotel suite, including Baez, was involved in drug trafficking.
    Because the officers had probable cause to believe that Baez had committed a
    crime, Baez’s arrest was lawful. Therefore, the district court did not err in denying
    Baez’s motion to suppress the incriminating statements that he made while in
    custody.
    III.
    Next, Baez argues that the district court erred in failing to instruct the jury that
    it would “negate[] the specific intent required by the charges” if Baez participated
    in the drug-trafficking conspiracy with the intent to “assist ongoing federal
    investigations” and in the good-faith, even if unreasonable, belief that “his actions
    -13-
    were not criminal.” “We review jury instructions for an abuse of discretion.” United
    States v. Ghant, 
    339 F.3d 660
    , 664 (8th Cir. 2003).
    As the Government points out, the “innocent-intent” instruction that Baez
    demanded misstates the law. An intention to assist law enforcement is not a defense
    to a criminal charge. See, e.g., United States v. Kabat, 
    797 F.2d 580
    , 589 (8th Cir.
    1986) (affirming a jury instruction to disregard the defendants’ further intentions or
    “motive[s], good or bad,” “laudable or not,” if the prosecution “established beyond
    a reasonable doubt the essential elements of each offense” (emphasis omitted)).
    Likewise, “the usual rule [is] that ignorance of the law is no defense to a criminal
    charge.” United States v. Lalley, 
    257 F.3d 751
    , 755 (8th Cir. 2001). Although the
    Supreme Court has “carv[ed] out an exception to [this] rule” for “highly technical
    statutes that present[] the danger of ensnaring individuals engaged in apparently
    innocent conduct,” Bryan v. United States, 
    524 U.S. 184
    , 194-95 (1998), the crimes
    with which Baez was charged do not fall within this exception, see McFadden v.
    United States, 
    576 U.S. 186
    , 192 (2015) (“Take, for example, a defendant who
    knows he is distributing heroin but does not know that heroin is listed on the
    schedules. Because ignorance of the law is typically no defense to criminal
    prosecution, this defendant would . . . be guilty of knowingly distributing a
    controlled substance.” (internal quotation marks and citations omitted)).
    Therefore, even if Baez intended to assist law enforcement and believed that
    “his actions were not criminal,” that would not negate his mens rea. The district
    court did not abuse its discretion in declining to instruct the jury otherwise. See
    United States v. McQuarry, 
    726 F.2d 401
    , 402 (8th Cir. 1984) (concluding that the
    district court did not abuse its discretion in declining to give a legally “unsupported”
    jury instruction).
    IV.
    Next, Baez challenges the district court’s exclusion of evidence related to the
    “innocent-intent” theory behind his proposed jury instruction. “We review
    -14-
    evidentiary rulings for abuse of discretion.” United States v. Gustafson, 
    528 F.3d 587
    , 590 (8th Cir. 2008).
    Under the Federal Rules of Evidence, evidence is admissible only if it is
    relevant. Fed. R. Evid. 402. Evidence is relevant if and only if “(a) it has any
    tendency to make a fact more or less probable than it would be without the
    evidence; and (b) the fact is of consequence in determining the action.” Fed. R.
    Evid. 401. Even if evidence is relevant, the trial court “may exclude [it] if its
    probative value is substantially outweighed by a danger of,” inter alia, “confusing
    the issues” or “misleading the jury.” Fed. R. Evid. 403.
    Here, the evidence that Baez sought to admit was inadmissible under Rule 402
    because it was irrelevant. The evidence falls into two categories: (1) evidence
    regarding an individual who asked Baez to translate at a meeting with a federal agent
    where the individual proposed serving as an informant on drug activities in North
    Carolina; and (2) evidence regarding Baez’s mental health. Baez claims that both
    sets of evidence are relevant insofar as they support his “innocent-intent” defense:
    (1) the evidence regarding the potential informant because it tends to show that Baez
    intended to assist in a federal investigation; and (2) the evidence regarding Baez’s
    mental health because it explains how he could believe in good faith that his actions
    were assisting law enforcement and were not criminal. As explained above,
    however, Baez’s alleged further intentions and ignorance of the law are of no
    consequence in determining his guilt. See supra Part III. Therefore, neither set of
    evidence is relevant under Rule 401, which means that neither is admissible under
    Rule 402.
    Furthermore, even if the evidence had been relevant, the district court was
    within its discretion to exclude it under Rule 403 because the risk that it would
    confuse issues or mislead the jury substantially outweighed whatever slight
    probative value it may have had. Testimony regarding a potential informant’s
    activities in North Carolina would have distracted from the events in Minnesota for
    which the Government was prosecuting Baez, and evidence of Baez’s mental health
    -15-
    may have caused the jury to confuse Baez’s “innocent-intent” defense with an
    insanity defense. Therefore, even if the evidence had been admissible under
    Rule 402, the court was within its discretion to exclude it under Rule 403. See
    United States v. Hillsberg, 
    812 F.2d 328
    , 333 (7th Cir. 1987) (affirming the
    exclusion of evidence related to the defendant’s mental state under Fed. R. Evid. 403
    on the ground that it “could have improperly brought the insanity issue in through
    the back door”).
    We conclude that the district court did not abuse its discretion in excluding
    evidence regarding the potential informant in North Carolina and Baez’s mental
    health.
    V.
    Next, Baez challenges the district court’s partial denial of his motion to
    compel the Government to disclose putative Brady material regarding the potential
    informant in North Carolina after in camera review. We review the denial of a
    motion to compel disclosure of Brady material after in camera review for abuse of
    discretion. United States v. Pendleton, 
    832 F.3d 934
    , 941-42 (8th Cir. 2016).
    Under Brady, “[t]he government has an obligation to disclose evidence that is
    favorable to the accused and material to either guilt or punishment.” United States
    v. Ladoucer, 
    573 F.3d 628
    , 636 (8th Cir. 2009). Evidence favorable to the defendant
    includes not only exculpatory evidence but also evidence that tends to impeach
    government witnesses. United States v. Bagley, 
    473 U.S. 667
    , 676 (1985). Evidence
    is material “if there is a reasonable probability that, had the evidence been disclosed
    to the defense, the result of the proceeding would have been different.” Kyles v.
    Whitley, 
    514 U.S. 419
    , 433 (1995). “The question is not whether the defendant
    would more likely than not have received a different verdict with the evidence,” but
    whether “its absence . . . undermines confidence in the outcome of the trial.” 
    Id. at 434
    .
    -16-
    Here, the district court ordered the disclosure of what little of the evidence
    was arguably favorable to Baez. Having reviewed the remainder of the evidence,
    we agree with the district court that Brady did not require its disclosure. It was not
    exculpatory, and it did not tend to impeach a Government witness. Therefore, it was
    not even favorable to Baez, let alone material in the sense that its nondisclosure
    undermines confidence in the outcome of the trial.
    We conclude that the district court did not abuse its discretion in partially
    denying Baez’s motion to compel disclosure of evidence regarding the potential
    informant in North Carolina.
    VI.
    Finally, Baez argues that he is entitled to resentencing because his sentence is
    substantively unreasonable. “We review the substantive reasonableness of a
    sentence under [a] deferential abuse-of-discretion standard.” United States v.
    Lazarski, 
    560 F.3d 731
    , 733 (8th Cir. 2009). Where a sentencing court varied
    downward from the guidelines, “it is nearly inconceivable that the court abused its
    discretion in not varying downward still further.” 
    Id.
    Here, the district court varied downward from the guidelines by more than
    fifty percent. Baez claims that the sentence was nonetheless substantively
    unreasonable because it was higher than the sentences imposed on Baez’s
    coconspirators. See United States v. Fry, 
    792 F.3d 884
    , 892-93 (8th Cir. 2015)
    (treating objections to sentencing disparities among coconspirators as substantive-
    reasonableness challenges). But “the statutory direction to avoid unwarranted
    sentence disparities, see 
    18 U.S.C. § 3553
    (a)(6), refers to national disparities, not
    differences among co-conspirators.” 
    Id. at 892
    . By itself, the fact that “a similarly
    situated co-conspirator was sentenced differently” provides “no principled basis for
    an appellate court to say which defendant received the ‘appropriate’ sentence.” 
    Id. at 893
    . Moreover, Baez was not similarly situated to his coconspirators; for
    example, he was the only one not to plead guilty. Consequently, the disparity
    -17-
    between his sentence and theirs was not unreasonable. See 
    id.
     (explaining that
    “disparate sentences among dissimilar defendants,” such as those who “pleaded
    guilty and accepted responsibility” and those who did not, “are not unwarranted”).
    This is not the “nearly inconceivable” case in which a district court that varied
    downward from the guidelines nonetheless “abused its discretion in not varying
    downward still further.” See Lazarski, 
    560 F.3d at 733
    . 3
    VII.
    For the foregoing reasons, we affirm.
    LOKEN, Circuit Judge, concurs in the judgment and joins the opinion except
    Section II.A.2.
    ______________________________
    3
    To the extent that Baez means to suggest that the district court failed to give
    adequate consideration to § 3553(a)(6), he is raising a claim of procedural error that
    we review by asking whether it is “clear from the record that the district court
    actually considered [§ 3553(a)(6)] in determining the sentence.” United States v.
    Salazar-Aleman, 
    741 F.3d 878
    , 881 (8th Cir. 2013). Here, it is clear from the record
    that the district court considered § 3553(a)(6) because the district court explicitly
    cited § 3553(a)(6) in its explanation for its downward variance. Therefore, to the
    extent that Baez means to argue that the district court committed procedural error by
    failing to consider § 3553(a)(6), his claim fails.
