    Defendant - Appellant.
    ORDER AND JUDGMENT *
    Before HARTZ, HOLMES, and EID, Circuit Judges.
    Defendant-Appellant David William Wilcox appeals from the district
    court’s denial of his motion to withdraw his guilty plea. Mr. Wilcox argues that
    the district court abused its discretion when it found that his assertion of
    innocence was not credible based on Mr. Wilcox’s previous admission that he
    knew he was required to register as a sex offender and that he did not do so when
    he arrived in Oklahoma. Specifically, Mr. Wilcox argues that the district court
    erred because he never admitted to knowing that he was not “properly registered”
    *
    This order and judgment is not binding precedent, except under the
    doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,
    however, for its persuasive value consistent with Federal Rule of Appellate
    Procedure 32.1 and Tenth Circuit Rule 32.1.

    at the time of the offense. Exercising jurisdiction under 
    28 U.S.C. § 1291
    , and
    for the reasons that follow, we affirm.
    I
    In 2014, Mr. Wilcox was convicted of a sex offense in North Dakota state
    court. This required him to register as a sex offender under both state and federal
    law. After his release from prison for the sex crime, Mr. Wilcox remained in
    North Dakota. While there, he complied with the sex-offender registration
    requirements. This included acknowledging that he was required to register with
    local law enforcement within three days of entering another city, county, or state
    where he intended to reside.
    In September 2018, Mr. Wilcox told North Dakota law enforcement that he
    intended to move to Muskogee, Oklahoma, with “an intended activation date of
    September 21, 2018.” R., Vol. III, ¶ 8 at 2 (Presentence Investigation Report,
    dated May 19, 2020) [hereinafter “PSR”]. Mr. Wilcox last updated his
    registration in North Dakota on September 19, 2018. In the same registration
    form, he again acknowledged that he was required to register with law
    enforcement within three days of entering a new jurisdiction or every three days if
    he became homeless.
    Mr. Wilcox never registered as a sex offender in Oklahoma. On September
    16, 2019, he was arrested. He told the police that “he had not made contact with
    any law enforcement after arriving in Oklahoma and was under the impression
    2
    Appellate Case: 20-7047   Document: 010110700612        Date Filed: 06/23/2022   Page: 3
    that once he left North Dakota he did not have to register as a sex offender.” 
    Id.
     ¶
    10 at 2.
    Mr. Wilcox was charged with traveling “in interstate commerce and
    knowingly fail[ing] to register and update his registration” from October 21,
    2018, to September 16, 2019, as required by the Sex Offender Registration and
    Notification Act (“SORNA”) in violation of 
    18 U.S.C. § 2250
    (a). R., Vol. I, at 9
    (Indictment, filed Dec. 11, 2019). A few months after being charged, Mr. Wilcox
    notified the court that he intended to plead guilty.
    After conducting the advisements required by Federal Rule of Criminal
    Procedure 11 at the change of plea hearing, the court 1 asked Mr. Wilcox whether
    his attorney had discussed with him the “essential elements of the charge” and
    whether he understood them. R., Vol. II, at 21 (Change of Plea Hr’g Tr., dated
    Mar. 4, 2020). Mr. Wilcox answered “yes” to both inquiries. 
    Id.
     The court then
    told Mr. Wilcox to explain “what [he] did or how did [he] commit the acts in
    connection with the charge made against [him].” 
    Id.
     at 21–22. Mr. Wilcox
    explained:
    I had been convicted of a felony offense in the state of North
    Dakota, which required me to register as a sex offender.
    Between October the 18th and September 16th of 2019, I was
    required to register as a sex offender. I moved to the state of
    Oklahoma where I am required to register as a sex offender.
    1
    With consent, a magistrate judge presided over Mr. Wilcox’s change
    of plea hearing.
    3
    Appellate Case: 20-7047    Document: 010110700612       Date Filed: 06/23/2022   Page: 4
    While in Oklahoma, I failed to update my registration
    information with local law enforcement.
    
    Id. at 22
    . The court asked “what dates were [you] involved in that?” 
    Id.
     Mr.
    Wilcox responded, “October 21st of 2018 and September the 16th of 2019”—i.e.,
    the date range for the offense charged in the indictment. 
    Id.
     The court then asked
    if Mr. Wilcox’s statement constituted all of the elements of the underlying
    offense, and the prosecutor answered, “yes.” 
    Id.
     The court accepted Mr.
    Wilcox’s guilty plea.
    About seven weeks after entering his guilty plea, Mr. Wilcox told the court
    in a pro se letter that he found the registration requirements “confusing” and “had
    to rely on the officials” at the police department in North Dakota to explain them
    to him. R., Vol. I, at 26 (Second Pro Se Letter, filed Apr. 24, 2020). In the same
    letter, Mr. Wilcox said an officer in North Dakota told him that “everything was
    tak[en] care of” in Oklahoma, and once he got to Oklahoma, he would have to
    update his registration once a year. 
    Id.
     at 26–27. Mr. Wilcox stated that—based
    on that advice about the purported one-year registration requirement—at the time
    of his arrest, he “still thought [that] [he] had a month to update [his]
    registr[ation]” because he arrived in Oklahoma “on October 28, 2018.” 
    Id. at 27
    .
    In this regard, Mr. Wilcox proclaimed that he “truly did not believe [he] was
    breaking any laws.” 
    Id.

    Appellate Case: 20-7047     Document: 010110700612      Date Filed: 06/23/2022   Page: 5
    Three months later, Mr. Wilcox’s attorney withdrew, and the court
    appointed new counsel. Shortly after being appointed, the new counsel filed a
    motion to withdraw Mr. Wilcox’s guilty plea. The motion focused on Mr.
    Wilcox’s assertion of innocence. Specifically, Mr. Wilcox argued that “he
    thought he was properly registered in Oklahoma,” and, therefore, “Defendant is
    making a good faith assertion of his innocence.” 
    Id. at 40
     (Def.’s Mot. to
    Withdraw[] Plea of Guilty and Br. in Supp., filed July 24, 2020).
    At the sentencing hearing, the court considered Mr. Wilcox’s motion to
    withdraw his guilty plea. After hearing from both parties, the court denied the
    motion to withdraw the guilty plea. The court noted that “at the plea hearing, the
    defendant said under oath that he knew about the registration requirement and
    while in Oklahoma [Mr. Wilcox] failed to update [his] registration information
    with local law enforcement, which belies his statement now that he thought he
    was registered.” R., Vol. II, at 31 (Mot. and Sentencing Hr’g Tr., dated Aug. 5,
    2020).
    After denying the motion to withdraw the guilty plea, the court asked the
    parties whether they had any objections to the PSR. There being none, the court
    accepted it as the factual basis for the court’s sentence. The court sentenced Mr.
    Wilcox to a term of 33 months’ imprisonment. Mr. Wilcox appeals.

    “Defendants do not have an absolute right to withdraw a guilty plea.”
    United States v. Siedlik, 
    231 F.3d 744
    , 748 (10th Cir. 2000). After a court has
    accepted a guilty plea, but before it has imposed a sentence, a defendant may
    withdraw his plea by showing “a fair and just reason for requesting the
    withdrawal.” F ED . R. C RIM . P. 11(d)(2)(B). It is the defendant’s burden to
    establish “a fair and just reason for requesting the withdrawal.” United States v.
    Hamilton, 
    510 F.3d 1209
    , 1214 (10th Cir. 2007) (quoting F ED . R. C RIM . P.
    11(d)(2)(B))). This is because “[w]ere withdrawal automatic in every case . . . ,
    the guilty plea would become a mere gesture, a temporary and meaningless
    formality . . . . In fact, however, a guilty plea is no such trifle, but a ‘grave and
    solemn act,’ which is ‘accepted only with care and discernment.’” United States
    v. Hyde, 
    520 U.S. 670
    , 677 (1997) (quoting F ED . R. C RIM . P. 32, advisory
    committee note to 1983 amendment). Therefore, a defendant “is not entitled to
    withdraw his plea simply because he possesses a non-frivolous defense theory;
    rather, on appeal, he must show that the district court ‘acted unjustly or
    unfairly.’” United States v. Garcia, 
    577 F.3d 1271
    , 1274 (10th Cir. 2009)
    (quoting Hamilton, 
    510 F.3d at 1214
    ).
    “We have identified some considerations that can help illuminate whether a
    particular request qualifies . . . .” United States v. Soto, 
    660 F.3d 1264
    , 1267
    (10th Cir. 2011). Specifically, to determine whether a defendant has met his
    6
    Appellate Case: 20-7047   Document: 010110700612        Date Filed: 06/23/2022      Page: 7
    burden to show a fair and just reason for withdrawing his guilty plea, we consider
    the following seven factors: “(1) whether the defendant has asserted his
    innocence, (2) prejudice to the government, (3) delay in filing defendant’s
    motion, (4) inconvenience to the court, (5) defendant’s assistance of counsel, (6)
    whether the plea is knowing and voluntary, and (7) waste of judicial resources.”
    United States v. Gordon, 
    4 F.3d 1567
    , 1572 (10th Cir. 1993). But “we have also
    recognized that the Rule’s standard—inviting and even commanding a general
    inquiry into fairness and justice—is not so easily captured and
    compartmentalized.” Soto, 
    660 F.3d at 1267
    . Therefore, “we have explained, it
    always and ultimately lies ‘within the sound discretion of the district court to
    determine’ on a case by case basis when the standard is and isn’t met.” 
    Id.
    (quoting Gordon, 
    4 F.3d at 1572
    ). Consequently, even though a motion to
    withdraw a guilty plea should be “freely allowed,” we will only reverse a district
    court when the defendant has shown the court acted “unjustly or unfairly.”
    United States v. Marceleno, 
    819 F.3d 1267
    , 1272 (10th Cir. 2016) (quoting
    Garcia, 
    577 F.3d at 1274
    ).
    In accord with these legal principles, we review a district court’s denial of
    a motion to withdraw a guilty plea under “our ‘deferential’ abuse-of-discretion
    standard.” 2 United States v. Dominguez, 
    998 F.3d 1094
    , 1103 (10th Cir. 2021)
    2
    We have recognized that two Gordon factors—“whether the plea was
    knowing and voluntary and, if reviewable on direct appeal, whether counsel

    (quoting United States v. Byrum, 
    567 F.3d 1255
    , 1259 (10th Cir. 2009)); see also
    Soto, 
    660 F.3d at 1267
     (“[W]e retain our traditional function to review the district
    court’s decision for an abuse of discretion and to delineate appropriate rules
    regarding when ‘the defendant can [and cannot] show that the court acted unjustly
    or unfairly.’” (second alteration in original) (quoting Gordon, 
    4 F.3d at
    1572–73)).
    We have “traditionally understood [the abuse of discretion standard] to
    mean that we will reverse a determination only if the court ‘exceeded the bounds
    of permissible choice,’ given the facts and the applicable law in the case at hand.”
    United States v. McComb, 
    519 F.3d 1049
    , 1053 (10th Cir. 2007) (quoting United
    States v. Ortiz, 
    804 F.2d 1161
    , 1164 n.2 (10th Cir. 1986)). In this regard,
    frequently, “there will be a range of possible outcomes [that] the facts and law at
    issue can fairly support; rather than pick and choose among them ourselves, we
    will defer to the district court’s judgment so long as it falls within the realm of
    these rationally available choices.”

     Nevertheless, “we will not hesitate to

    1272. On the other hand, we “have been careful to avoid singling out individual
    Gordon factors for more deferential review.” Id. (explaining that although “[t]he
    district court styled its conclusions regarding [the defendant’s] assertion of
    innocence as ‘findings of fact’. . . which we typically review only for clear error .
    . . [t]o review the district court’s overall conclusion on the credibility of [the
    defendant’s] assertion of innocence only for clear error would deviate from our
    previous treatment of motions to withdraw a guilty plea” (emphasis added)
    (citations omitted)).

    or an erroneous conclusion of law or manifests a clear error of judgment.’” Id. at
    1054 (quoting Cartier v. Jackson, 
    59 F.3d 1046
    , 1048 (10th Cir. 1995)).
    III
    Mr. Wilcox argues that the district court erred in denying his motion to
    withdraw his guilty plea because he thought he was “properly registered” at the
    time of the offense, and therefore, was innocent. We will first summarize the
    legal standard for assessing the merits of an assertion of innocence claim—the
    only element that Mr. Wilcox contests. Then, we will explain why Mr. Wilcox
    cannot show the district court abused its discretion in denying his motion.
    A
    To prevail on an assertion of innocence claim, a defendant must make an
    argument that is both credible and supportive of a legally cognizable defense.
    Marceleno, 819 F.3d at 1273; see Hamilton, 
    510 F.3d at 1214
     (“[T]he mere
    assertion of a legal defense is insufficient; the defendant must present a credible
    claim of legal innocence.”). “A district court need not accept a defendant’s
    version of the facts as true for purposes of evaluating whether a defendant’s
    assertion of innocence is credible.” Marceleno, 819 F.3d at 1274–75. We have
    explained that “[t]o hold otherwise would undermine Rule 11 by removing the
    discretion granted to district courts on motions to withdraw a guilty plea.” Id. at
    1275. Instead, we have explained that a credible claim is one that “‘has the
    9
    Appellate Case: 20-7047    Document: 010110700612       Date Filed: 06/23/2022    Page: 10
    quality or power of inspiring belief,’ and ‘tends to either defeat the elements in
    the government’s prima facie case or make out a successful affirmative defense.’”
    Id. (quoting United States v. Thompson-Riviere, 
    561 F.3d 345
    , 353 (4th Cir.
    2009)). In keeping with our overall standard of review for a denial of a motion to
    withdraw a guilty plea, we review the court’s determination as to the
    assertion-of-innocence factor for an abuse of discretion. See id. at 1272 (noting
    we have declined to adopt a clear error standard to review a district court’s
    overall conclusion on the credibility of a defendant’s assertion of innocence
    because doing so “would deviate from our previous treatment” of “avoid[ing]
    singling out individual Gordon factors for more deferential review” when
    considering motions to withdraw a guilty plea).
    B
    Reviewing the district court’s denial of Mr. Wilcox’s motion to withdraw
    his guilty plea for an abuse of discretion, we conclude that the district court did
    not act “unjustly or unfairly” or otherwise abuse its discretion when it concluded
    that Mr. Wilcox’s assertion of innocence was not credible in light of his previous
    statements at the change of plea hearing. The district court’s finding that Mr.
    Wilcox’s assertion of innocence was not credible reflects—at the very least—a
    plausible view of the import of his statements at that hearing. As the district
    court saw it, those statements belied (i.e., were inconsistent with) Mr. Wilcox’s
    10
    Appellate Case: 20-7047    Document: 010110700612       Date Filed: 06/23/2022    Page: 11
    assertion of innocence. In sum, the court did not abuse its discretion by denying
    Mr. Wilcox’s motion to withdraw his guilty plea.
    To decide this issue, we must determine what Mr. Wilcox is and is not
    arguing. As to the latter, it is notable that Mr. Wilcox does not argue that he is
    innocent because he does not satisfy the legal mens rea requirement for
    knowingly failing to register as a sex offender; indeed, he explicitly asks us not to
    consider this mens-rea question. See Aplt.’s Opening Br. at 7 n.2. Specifically,
    Mr. Wilcox notes that we have not defined what the “knowingly” element means
    in the context of § 2250(a). Id. (citing United States v. Forster, 549 F. App’x
    757, 762 n.2 (10th Cir. 2013)). He points out that “[t]he circuits to have
    addressed the issue have held that the ‘knowingly’ element of section 2250(a)
    requires only that a defendant have knowledge that he was legally required to
    register as a sex offender.” Id.; see, e.g, United States v. Vasquez, 
    611 F.3d 325
    ,
    328 (7th Cir. 2010) (“Today we join the Fourth, Fifth, Eighth, and Eleventh
    Circuits . . . and hold that SORNA merely requires that a defendant have
    knowledge that he was required by law to register as a sex offender.”); 
    id. at 329
    (“To that end, a defendant can be convicted under SORNA if the government can
    prove that he knew he was required to register as a sex offender.”). Mr. Wilcox
    says that we need “not [decide the mens rea question] here.” Aplt.’s Opening Br.
    at 7 n.2. He explains that this would be unnecessary because he “claims not that
    11
    Appellate Case: 20-7047    Document: 010110700612       Date Filed: 06/23/2022     Page: 12
    he was unaware of SORNA’s requirements in particular but that he generally
    believed he was properly registered.” 
    Id.
    Mr. Wilcox frames his challenge as a factual one. He argues that the
    district court found his assertion of innocence not to be credible “based on a
    misreading of the record.” Id. at 8. In his motion to withdraw his guilty plea,
    Mr. Wilcox argued that he was actually innocent because he did not knowingly
    fail to register as a sex offender and instead “thought that he was properly
    registered in Oklahoma.” R., Vol. I, at 39. The district court did not find this
    credible in light of his testimony at the change of plea hearing where he admitted
    that he knew that he was required to register as a sex offender and that he did not
    do so upon arriving in Oklahoma. So here, Mr. Wilcox argues that the district
    court abused its discretion because the court based its conclusion on a clearly
    erroneous reading of the record—specifically, that nowhere in the record did Mr.
    Wilcox admit that he knew at the time of the offense that he was not “properly
    registered” in Oklahoma. Aplt.’s Opening Br. at 6.
    We disagree with Mr. Wilcox’s contention that the district court abused its
    discretion by finding that his assertion of innocence was not credible because it
    misread the record. As the district court plausibly (indeed, reasonably) explained,
    “in his statement of the factual basis at the plea hearing, the defendant said under
    oath that he knew about the registration requirement and while in Oklahoma [he]
    failed to update [his] registration information with local law enforcement, which
    12
    Appellate Case: 20-7047     Document: 010110700612       Date Filed: 06/23/2022     Page: 13
    belies his statement now that he thought he was registered.” R., Vol. II, at 31; see
    id. at 22 (“I had been convicted of a felony offense . . . which required me to
    register as a sex offender. Between October the 18th [of 2018] and September
    16th of 2019, I was required to register as a sex offender. . . . While in Oklahoma,
    I failed to update my registration information with local law enforcement.”); id.
    (replying to “what dates were [you] involved in that,” Mr. Wilcox answered,
    “October 21st of 2018 and September the 16th of 2019”).
    In other words, the court plausibly found that, based on his statements, Mr.
    Wilcox had effectively admitted at the change of plea hearing (1) that he knew
    about the registration requirement and (2) while in Oklahoma, he had failed to
    register. The court concluded that Mr. Wilcox’s subsequent assertion of
    innocence was belied by these statements; that is, his assertion was not credible.
    This conclusion is grounded in a permissible reading of the record—even if it is
    not the only plausible reading of the record—and, therefore, the court did not
    clearly err. See, e.g., Anderson v. City of Bessemer City, 
    470 U.S. 564
    , 574
    (1985); accord United States v. Ellis, 
    23 F.4th 1228
    , 1241 (10th Cir. 2022). And
    the court did not otherwise act “unjustly or unfairly” in rejecting Mr. Wilcox’s
    argument for relief. See Garcia, 
    577 F.3d at 1274
     (quoting Hamilton, 
    510 F.3d at 1214
    ).
    Yet Mr. Wilcox contends that there was no contradiction between his
    statements at the change of plea hearing and his subsequent assertion of
    13
    Appellate Case: 20-7047    Document: 010110700612        Date Filed: 06/23/2022     Page: 14
    innocence. As Mr. Wilcox reasons, that is because he never admitted that he
    knew that, at the time of the charged offense, he was not “properly registered” in
    Oklahoma. And it is undisputed that the district court did not purport to make
    any finding—much less an adverse one—concerning whether Mr. Wilcox knew
    that he was “properly registered” at the time of the offense.
    However, Mr. Wilcox fails to demonstrate the relevancy of this “properly
    registered” contention to the factual challenge that he has presented here: that is,
    his challenge to the district court’s determination—based on its reading of his
    statements at the change of plea hearing—that his assertion of innocence was not
    credible. More specifically, to understand why Mr. Wilcox’s argument that he
    did not know he was not “properly registered” while in Oklahoma does not save
    his assertion of innocence claim, it is important first to understand what Mr.
    Wilcox means by “properly registered.” To Mr. Wilcox, “properly registered”
    means that, at the time of his charged offense, he did not know that by not
    registering in Oklahoma he was not in compliance with his SORNA registration
    requirement.
    In effect, Mr. Wilcox argues that he had to know at the time of the offense
    that he was not in a lawful registration status (i.e., “properly registered”). See,
    e.g., Aplt.’s Opening Br. at 1 (“[H]e was unaware at the time of the alleged
    offense that he was not properly registered as a sex offender. . . . Mr. Wilcox
    never admitted at the change of plea hearing to knowing he was not properly
    14
    Appellate Case: 20-7047    Document: 010110700612        Date Filed: 06/23/2022    Page: 15
    registered at the time the offense allegedly occurred.”); id. at 3 (“But he did not
    admit that he had known he was not properly registered at the time of the alleged
    offense.”); id. at 4–5 (“Mr. Wilcox ‘thought he was properly registered in
    Oklahoma’. . . . Mr. Wilcox averred that he had repeatedly explained to his
    previous lawyer that he thought he ‘had properly registered.’”); see also Aplt.’s
    Reply Br. at 1 (“While his admission demonstrates that he knew he had failed to
    properly register at the time he pled guilty, it does not show that he knew he
    wasn’t properly registered at the time of the alleged offense.” (emphases
    omitted)); id. (“[B]y the time he pleaded guilty, Mr. Wilcox had been appointed
    an attorney who undoubtedly reviewed the discovery with him and explained that,
    in fact, he had not been properly registered, regardless of what he had thought at
    the time.”); id. at 2 (“Because Mr. Wilcox’s admissions at the change of plea
    hearing would not compel a finding that he knew he wasn’t properly registered at
    the time of the alleged offense, it certainly would not exceed the bounds of
    permissible choice for the court to decline to make that finding.”).
    This argument is consistent with Mr. Wilcox’s prior claim in his pro se
    letter to the district court that “[he] truly did not believe [he] was breaking any
    laws.” R., Vol. I, at 27. But it is worth underscoring that Mr. Wilcox is not
    arguing that he did not have knowledge of the registration requirement or that he
    believed he had actually registered in Oklahoma. See 
    18 U.S.C. § 2250
    (a)
    (“Whoever . . . is required to register under [SORNA]. . . and (3) knowingly fails
    15
    Appellate Case: 20-7047      Document: 010110700612     Date Filed: 06/23/2022       Page: 16
    to register or update a registration as required by [SORNA] . . . shall be fined
    under this title or imprisoned . . . .”).
    As we see it, then, Mr. Wilcox’s argument that the district court misread
    the record in perceiving a contradiction between his statements at the change of
    plea hearing and his subsequent assertion of innocence is tacitly predicated on a
    particular theory regarding the nature of the mens-rea requirement of his
    registration offense. Under this theory, not only does a defendant need to know
    that he was legally required to register as a sex offender, but also that, when the
    crime was committed, he was not “properly” registered—that is, not lawfully
    registered.
    However, even under Mr. Wilcox’s own reading of the caselaw, our sister
    circuits have repeatedly adopted a different mens-rea theory, see Vasquez, 
    611 F.3d at 328
    , and we have not opined on the specific subject, see Aplt.’s Opening
    Br. at 7 n.2. And more problematic still for Mr. Wilcox, he has expressly
    disclaimed any intention of challenging the district court’s view of the mens-rea
    standard and, indeed, has told us there is no need for us to reach the issue of the
    proper mens-rea standard. See Aplt.’s Opening Br. at 7 n.2. That is, Mr. Wilcox
    has not argued on appeal that the district court committed legal error by not
    adopting a particular mens-rea theory—including the one he tacitly endorses
    16
    Appellate Case: 20-7047    Document: 010110700612       Date Filed: 06/23/2022   Page: 17
    here—and he expressly disclaims any interest in us reaching this conclusion. 3
    3
    Though Mr. Wilcox explicitly tells us that we need not opine on the
    nature of the mens-rea requirement for his SORNA offense, he seems to tacitly
    pursue a contrary course through a 28(j) letter. Following our decision in United
    States v. Perez-Perez, 
    992 F.3d 970
     (10th Cir. 2021), Mr. Wilcox filed a 28(j)
    letter arguing that his admission of improper registration “at the time of his guilty
    plea is ‘of questionable significance as to his knowledge of his status at the time
    of the offense,’ because the mere fact that he ‘now knows’ he was not properly
    registered ‘does not mean’ that he was aware of his failure to properly register ‘at
    the time of the offense.’” Aplt.’s 28(j) Letter at 2. Mr. Wilcox’s reliance on
    Perez-Perez, however, is unavailing. First, Mr. Wilcox fails to cite any legal
    authority that would call for the application of the holding of Perez-Perez here;
    and second, Mr. Wilcox did not expressly advance his particular mens-rea
    theory—which he intimates is similar to the defendant’s theory in Perez-
    Perez—in his opening brief and therefore it is waived.
    More specifically, there is no legal basis for Mr. Wilcox to equate his
    circumstances to those in Perez-Perez. In Perez-Perez, we concluded that the
    defendant’s guilty plea was invalid because he was not informed at the time of his
    plea that the government would have to prove that he “knew he was illegally or
    unlawfully in the United States at the time of the offense.” Perez-Perez, 992 F.3d
    at 973. Mr. Wilcox essentially seeks to analogize his circumstances to those of
    the defendant in Perez-Perez: as his argument seems to go, just as Mr. Wilcox did
    not admit at the change of plea hearing that he knew he was not “properly
    registered” at the time of his offense, the defendant in Perez-Perez did not admit
    that he knew he was illegally or unlawfully in the United States at the time of his
    offense. However, notably, the Perez-Perez’s defendant’s knowledge of his
    unlawful status in this regard was a legally relevant fact—indeed, a requisite
    element of his offense. In contrast, Mr. Wilcox has presented no legal authority
    to even suggest that his knowledge that he was not, at the time of the offense,
    “properly registered”—i.e., not lawfully registered—was likewise a legally
    relevant fact to his plea, much less a requisite element of his offense. Indeed, as
    he seemingly recognizes, other circuits to consider this question uniformly have
    reached a contrary conclusion—that “SORNA merely requires that a defendant
    have knowledge that he was required by law to register as a sex offender.”
    Vasquez, 
    611 F.3d at 328
    . In any event, as mentioned above, Mr. Wilcox
    explicitly indicated that we need not opine on the nature of the mens-rea element
    of his SORNA offense—which would include the mens-rea theory that he tacitly
    endorses here. Consequently, Mr. Wilcox has waived any argument for reversal
    (continued...)

    At bottom, then, Mr. Wilcox fails to explain why it is relevant to the
    challenge that he has presented that he failed to admit when he pleaded guilty that
    he knew at the time of the charged offense that he was not “properly registered”
    in Oklahoma. More specifically, Mr. Wilcox does not tell us why—as a factual
    matter—the absence of such an admission rendered the district court’s conclusion
    an abuse of discretion, that is, its conclusion that Mr. Wilcox’s assertion of
    innocence was not credible and specifically belied by his previous statements at
    the change of plea hearing. In this regard, we are hard pressed to understand how
    the district court could be deemed to have abused its discretion for failing to view
    Mr. Wilcox’s change of plea statements—and lack of admissions—through the
    prism of a legal theory that Mr. Wilcox himself acknowledges we have not
    previously opined on, and one he does not even urge us to adopt now. Stated
    otherwise, based on the factual challenge that is properly before us, we cannot
    conclude that the district court abused its discretion by relying on Mr. Wilcox’s
    prior statements to determine that his later assertion of innocence was not
    credible. See Marceleno, 819 F.3d at 1274 (“If the movant’s factual contentions .

    based on the similarity between his mens-rea theory and the theory espoused by
    the defendant in Perez-Perez; at Mr. Wilcox’s own explicit suggestion, his theory
    is not part of our decisional calculus. See Wyoming v. Livingston, 
    443 F.3d 1211
    ,
    1216 (10th Cir. 2006) (“Wyoming did not address this issue in its opening
    appellate brief. The issue is therefore waived.”); United States v. Black, 
    369 F.3d 1171
    , 1176 (10th Cir. 2004) (holding “[f]ailure to raise an issue in the opening
    appellate brief waives that issue” [when the issue was raised in] “a ‘supplemental
    memorandum brief’ filed almost two months after [the] reply brief”).

    . . make out no legally cognizable defense to the charges, he has not effectively
    denied his culpability.” (quoting Hamilton, 
    510 F.3d at
    1214–15)).
    In sum, resolving Mr. Wilcox’s appellate challenge on the terms he has
    defined—i.e., with the outcome of the challenge depending on whether the district
    court misread the record—we conclude that the district court’s rejection of Mr.
    Wilcox’s assertion of innocence as not credible was not based on a clearly
    erroneous understanding of the record and did not otherwise evince an abuse of
    discretion. Accordingly, we uphold the district court’s order denying Mr.
    Wilcox’s motion to withdraw his guilty plea.

    For the foregoing reasons, we AFFIRM the district court’s judgment. 4
