    DUNCAN, Circuit Judge:
    This    appeal     arises    from   a    conviction    and    sentence    for
    conspiracy to possess with intent to distribute marijuana and
    cocaine base, in violation of 21 U.S.C. § 846; use and carry of
    a firearm in relation to drug trafficking, in violation of 18
    U.S.C.   §    924(c);     conspiracy     to   obstruct,    delay    and    affect
    commerce     by   robbery,   in     violation    of   18   U.S.C.   §     1951(a);
    possession with intent to distribute marijuana, in violation of
    21 U.S.C. § 841(a)(1), (b)(1)(D), and 18 U.S.C. § 2; robbery
    affecting commerce, in violation of 18 U.S.C. § 1951(a); and
    being a felon in possession of a firearm, in violation of 18
    U.S.C.   §   922(g)(1).       The    appellant    challenges       the    district
    court’s denial of his motion to dismiss the indictment based on
    immunity and his motion to suppress evidence seized during a
    house search.      He also challenges the court’s decision to impose
    a mandatory minimum of life imprisonment pursuant to 21 U.S.C.
    § 841(b)(1)(A).       For the reasons that follow, we affirm.
    I.
    A.
    Starting in the 1990s, Romaine Abdul Short, together with
    others, belonged to a group known as “The Creek Boys.”                        This
    group,   among    other    things,     manufactured    powder      into   cocaine
    3
    base,      sold    crack    cocaine,     and      robbed    other      drug    dealers    of
    controlled substances.             In December 2004, Detective Eric Kempf
    of   the    Federal      Violent     Crimes       Task    Force    learned     of    Short’s
    activities, and asked Short if he would be willing to provide
    him with some information.                Short, who was then in custody on
    pending state drug violations, agreed, and thereafter, Detective
    Kempf and Short met several times from December 17, 2004 through
    March      2,    2005.      During    those       meetings,       Short     described    his
    involvement in crack cocaine and marijuana dealing, and gave
    Detective Kempf several names.                    Short also testified before a
    grand jury on drug related matters involving James Frink, Ricky
    Frink, and Germell Allmond.                 Afterwards, Detective Kempf sent a
    letter      to    the    Newport     News     Commonwealth         Attorney’s        Office,
    detailing Short’s cooperation.                 As a result of this letter, the
    state charges against Short were reduced.
    Short’s criminal activity continued after 2005.                             On April
    15, 2006, he and Sam Wallace, another Creek Boy, arranged to
    meet    a   drug    dealer       named   Joseph      Ocasio.          Wallace    had    told
    Ocasio’s contact, Sammy Zaharopoulos, that they wanted to buy
    marijuana,        but    they     actually        planned    to       rob   Ocasio.       In
    preparation,        Short    sought      assistance        from    Demario      Boyd,    who
    Short knew always carried a gun, would “straight take the weed
    from    [Ocasio],”         and   would    only      ask    for    a    small    amount    of
    4
    marijuana in return.           J.A. 573.       That evening, Wallace picked up
    Short and Boyd in his car and headed to the Bayberry Shopping
    Center to meet Ocasio.           While the marijuana purchase was taking
    place, Boyd brandished his gun and shot Ocasio in the back of
    the head, killing him.            Wallace and Boyd quickly fled on foot,
    while Short, carrying Ocasio’s marijuana sample, drove away in
    Wallace’s car.
    Responding to the murder, Detective Robert Vasquez located
    and    apprehended       Wallace.       Upon      questioning      him,       Detective
    Vasquez      learned    that    Short   had     been    involved   in     the    Ocasio
    murder.        The     next    day,   Detective        Vasquez   and    his     partner
    Detective Richard Espinoza visited Short’s residence with ten to
    twelve other police officers. 1            Detective Espinoza knocked on the
    door, announced himself, and then asked everyone inside to come
    out.       Short came out with his wife Shenika Short (“Ms. Short”)
    and two children.         He was placed in handcuffs and then taken to
    the police station for questioning.               At the same time, Detective
    Steven Smithley obtained consent to search the house from Ms.
    Short.      In the house, police officers found, among other things,
    1
    Detective Espinoza explained that they took such a large
    contingent because Boyd, potentially armed and dangerous,
    remained at large and could have been with Short, and because
    they had “not recover[ed] the murder weapon from the scene.”
    J.A. 56.

    marijuana, a digital scale, and a sealed plastic bag containing
    $1,000.
    B.
    Based    on   the   Ocasio   murder,   the     subsequent   search,   and
    evidence that from 1996 through 2007, Short purchased and sold
    firearms, marijuana, crack cocaine, and powder cocaine; robbed
    several drug dealers; and was armed with a weapon while drug
    trafficking, a federal grand jury in the Eastern District of
    Virginia indicted Short on September 12, 2007, for conspiracy to
    possess with intent to distribute marijuana and cocaine base in
    violation of 21 U.S.C. § 846; conspiracy to obstruct, delay, and
    affect commerce by robbery in violation of 18 U.S.C. § 1951(a);
    possession with intent to distribute marijuana in violation of
    21 U.S.C. § 841(a)(1), (b)(1)(D), and 18 U.S.C. § 2; robbery
    affecting       commerce    in   violation   of   18    U.S.C.   § 1951(a);   and
    possession of a firearm in furtherance of a drug trafficking
    crime in violation of 18 U.S.C. § 924(c)(1)(A).                  The government
    later    filed    a   superseding     indictment     that   added   charges   for
    possession with intent to distribute cocaine base in violation
    of 21 U.S.C. § 841(a)(1), (b)(1)A)(iii) and 18 U.S.C. § 2, and
    possession of a firearm by a felon in violation of 18 U.S.C.
    § 922(g)(1).
    6
    In   January    2008,   Short       moved    to     suppress    the    evidence
    seized during the warrantless search of his home on the ground
    that police conducted the search without valid consent.                        During
    a   hearing   on    the   motion,   Detective       Smithley       testified      that,
    following     Short’s     departure,          Detective     Smithley       approached
    Ms. Short,     “explained     to    her    what    was     going     on,    and   then
    ultimately just asked for a consent search for the residence.”
    J.A. 113.     He further testified that, after Ms. Short agreed to
    cooperate, he obtained a consent form, “explained [it] to her,”
    and watched her sign it.             J.A. 113.          According to Detective
    Smithley, police officers began the search only after obtaining
    consent.      Ms.    Short   also   testified      and     provided    a    different
    account.      Although she admitted giving consent, Ms. Short said
    that police officers entered her home before she had consented,
    and that she finally gave consent only because an officer said
    that she and her children would “have to stand outside until
    they got a search warrant.”           J.A. 180.         Ms. Short explained, “I
    didn’t want me and my kids to stand outside.                       It was kind of
    cold, so I didn’t think I had nothing to hide in my house, so I
    signed it.”     J.A. 182.     Ultimately, the district court found her
    testimony not credible and, concluding that “Ms. Short did give
    consent,” denied Short’s motion to suppress the evidence seized
    from his house.      J.A. 274.
    7
    Several     months     later,          Short        moved     to       dismiss        the
    superseding      indictment        on   the       ground     that       he    had    received
    immunity by cooperating with law enforcement regarding his March
    2005 grand jury testimony.               During a hearing on the motion,
    Detective Kempf explained that, although he gave Short a limited
    promise in exchange for his cooperation, there was an important
    caveat:     “[S]ince Mr. Short was in custody, . . . I advised him
    that    any   cooperation          he   gave        would     be        related       to    the
    Commonwealth Attorney since he had pending charges.                                 By law no
    promises could be made by me.                     I don’t have the authority to
    make any promises.”         J.A. 312.
    Short also testified and provided a different account.                                He
    said that Detective Kempf told him that “the only way that [he]
    w[ould] be safe from ever getting prosecuted for any [of these
    crimes] was for [him] to tell [Detective Kempf] everything from
    the first time [he] ever picked up a blunt weed.”                                   J.A. 343.
    Accordingly,       Short    testified        that     he    had     provided        Detective
    Kempf with his entire criminal background, believing that he
    would therefore be “protect[ed].”                  J.A. 350.
    During the hearing, Short also submitted his grand jury
    testimony     as    proof     of    immunity.              During       the     grand       jury
    proceeding,      Short     admitted     to    “hustling”          and    then       asked    the
    prosecutor whether he would get in trouble for this admission.
    8
    J.A. 1477.     The prosecutor responded, “No, you are fine.”                     
    Id. After confirming
    that Short was telling the truth and did not
    shoot anyone, the prosecutor said, “You’re fine.                       Go ahead.”
    
    Id. According to
        Short,     the    prosecutor     was     “verifying”
    Detective Kempf’s promise of immunity in exchange for Short’s
    grand jury testimony.         J.A. 351-52.
    Ultimately,     the     district   court    denied     Short’s    motion    to
    dismiss the superseding indictment.                It found that, at most,
    “[Short] had an informal use immunity agreement related to his
    grand jury testimony” and also that “none of the charges in the
    superseding indictment are related to [Short’s] brief grand jury
    testimony at issue here.”         J.A. 1202-03.
    The case then proceeded to trial and Short was found guilty
    on all but two counts. 2             After calculating Short’s applicable
    guideline    range    under    the    federal    sentencing    guidelines,       the
    district court imposed the mandatory minimum penalty of life
    imprisonment pursuant to 21 U.S.C. § 841(b)(1)(A) based upon two
    prior felony drug convictions.           This appeal followed.
    2
    Short was not found guilty of possessing a firearm in
    relation to a drug trafficking crime, in violation of 18 U.S.C.
    § 924(c)(1)(A), and knowingly and intentionally possessing with

    II.
    On   appeal,   Short    challenges    the    district     court’s      orders
    denying his motion to dismiss the superseding indictment and his
    motion to suppress.      He also challenges the court’s application
    of 21 U.S.C. § 841(b)(1)(A).        We consider each matter in turn.
    A.
    We consider first the district court’s denial of Short’s
    motion to dismiss the indictment based on a grant of immunity.
    We review the district court’s factual determinations concerning
    the existence and scope of an alleged immunity agreement for
    clear error, see United States v. Martin, 
    25 F.3d 211
    , 217 (4th
    Cir. 1994) (applying standard of review to plea agreement), and
    its application of the law de novo, see United States v. Smith,
    
    976 F.2d 861
    , 863 (4th Cir. 1992).
    In   this   context,    immunity     may    be   either      “transactional
    immunity” or “use and derivative use immunity.”                      Kastigar v.
    United States, 
    406 U.S. 441
    , 443 (1972).               Transactional immunity
    “accords full immunity from prosecution for the offense to which
    the . . . testimony relates.”         
    Id. at 453.
            Use and derivative
    use   immunity    prohibits   the   use    of    testimony    or    any   evidence
    intent to distribute cocaine base in violation                     of   21   U.S.C.
    § 841(a)(1), (b)(1)A)(iii) and 18 U.S.C. § 2.
    10
    derived from that testimony against the witness in a criminal
    prosecution.       See 
    id. at 452-53.
                Under this latter type of
    immunity, the witness still may be prosecuted for crimes about
    which he testifies if the government proves that it has other
    evidence that is derived from a source wholly independent of the
    testimony.       United States v. Jarvis, 
    7 F.3d 404
    , 414 (4th Cir.
    1993) (finding that “the government [is] free to use any other
    evidence to prosecute”).
    While an immunity agreement is typically “made when the
    parties verbally express their mutual assent to its essential
    terms,      it   may   also   be    implied      when   the   parties’       conduct
    manifests their agreement.”              United States v. McHan, 
    101 F.3d 1027
    , 1034 (4th Cir. 1996).              Under the doctrine of “equitable
    immunity,” immunity exists where: “(1) an agreement was made;
    (2)   the    defendant    has      performed     on   his   side;    and   (3)   the
    subsequent prosecution is directly related to offenses in which
    the defendant, pursuant to the agreement, either assisted with
    the   investigation      or     testified      for    the   government.”         
    Id. Ultimately, however,
    the defendant bears the burden of proving
    the existence of an equitable immunity agreement.                   
    Id. Applying this
    standard, the district court determined that
    Short failed to meet his burden of proving the existence of
    transactional      immunity.        At   most,    the   district     court    noted,
    11
    “based    on     a    review    of    [Short’s]       grand      jury    testimony        . . .
    [Short] had an informal use immunity agreement related to his
    grand    jury       testimony.”        J.A.     1202.        However,        because      Short
    “testified at the grand jury regarding matters and individuals
    which form no part of the current charges against [Short] in the
    superseding          indictment,”      J.A.    1202,      the    district       court     found
    that “even if [Short] did have [use] immunity as to his grand
    jury    testimony,       there       has   clearly      been     no     violation      by    the
    United States,” J.A. 1203.                 Short now challenges these findings.
    As proof that he received immunity, Short cites the statements
    made    by     the     prosecutor      before       the    grand      jury    as    well      as
    Detective Kempf’s statement that if Short told the truth and had
    not shot anyone, he would “be alright and not be prosecuted.”
    Appellant’s Br. at 19.
    Nothing in the record persuades us that the district court
    clearly erred in finding that the government did not agree to
    give Short immunity based on his interactions with Detective
    Kempf.        Short testified that Detective Kempf told him that “the
    only way that [he would] be safe from ever getting prosecuted
    for     any    of     [his     previous       crimes]     was     for     [him]     to      tell
    [Detective       Kempf]      everything        from    the      first    time      [he]     ever
    picked up a blunt weed.”                   J.A. 343.            By contrast, Detective
    Kempf explained that prior to their interview, he “advised him
    12
    that any cooperation . . . would be related to the Commonwealth
    Attorney since he had pending charges,” but that “[b]y law no
    promises could be made by [him]” because he did not have the
    authority.          J.A.    312.     Ultimately,      the       district   court    found
    Detective Kempf credible and Short unworthy of belief.                             We are
    given    no     reason       to     challenge       that        credibility     finding,
    particularly since during his testimony, Short admitted to lying
    to a probation officer about his drug use “to help [him]self.”
    J.A. 359.      See United States v. Thompson, 
    554 F.3d 450
    , 452 (4th
    Cir. 2009) (“[W]hen a district court’s factual finding is based
    upon    assessments         of     witness    credibility,         such    finding     is
    deserving      of     the     highest    degree       of    appellate      deference.”
    (internal quotations omitted)).                   The record indicates, at most,
    that Detective Kempf promised Short that he would write a letter
    on his behalf to the Commonwealth Attorney.                           Detective Kempf
    kept his promise, and as a result of this letter, Short was able
    to plead guilty to a reduced charge on a pending state matter.
    The    only    other      evidence    offered       in    support   of    Short’s
    motion was the grand jury testimony, but Short’s colloquy with
    the prosecutor does not evidence “a meeting of the minds that
    the government would refrain from further prosecuting him in
    exchange for his cooperation,” and thus, Short cannot establish
    transactional immunity.              
    McHan, 101 F.3d at 1034
    .                   All this
    13
    colloquy shows is Short asking the prosecutor whether he would
    get in trouble for “hustling,” and the prosecutor reassuring him
    that he would be fine.         J.A. 1477.            Even assuming that this
    colloquy    can   be   construed   as    a    grant   of    use   immunity,   the
    district court found, as a matter of fact, that the charges
    contained    in    the    superseding         indictment      were    based    on
    independent sources of information, and not based on any matters
    disclosed   by    Short   during   his       grand   jury   testimony.    Short
    offers no evidence to rebut this finding, 3 and thus, we conclude
    3
    At oral argument, Short argued that if we find that he was
    entitled to use immunity, we must find that the district court
    erred in failing to conduct a Kastigar hearing.     United States
    v. Harris, 
    973 F.2d 333
    , 336 (4th Cir. 1992) (noting that in a
    Kastigar hearing, the government must “demonstrate that all its
    evidence came from sources independent of the compelled
    testimony”).    We disagree.     “Whether the oral use-immunity
    agreement at issue in this case is subject to the full Kastigar
    protections is doubtful because [Short] voluntarily cooperated
    with the government.” 
    McHan, 101 F.3d at 1036
    ; see also United
    States v. Roberson, 
    872 F.2d 597
    , 611-12 (5th Cir.) (holding
    that where cooperation was not compelled but was voluntarily
    provided pursuant to a state immunity agreement, that agreement
    cannot bind federal prosecutors), cert. denied, 
    493 U.S. 861
    (1989); United States v. Eliason, 
    3 F.3d 1149
    , 1152-53 (7th Cir.
    1993) (same); United States v. Camp, 
    72 F.3d 759
    , 761 (9th Cir.
    1995) (same), cert. denied, 
    517 U.S. 1162
    (1996).     Further, to
    the extent that a full Kastigar hearing is ever appropriate in
    non-compulsion cases, it was not required in this case because,
    at most, the government provided Short with use immunity, not
    derivative use immunity, and there is no evidence in the record
    showing that the government directly used the immunized
    testimony.   See United States v. Smith, 
    452 F.3d 323
    , 337 (4th
    Cir. 2006) (finding no Kastigar hearing is required where the
    agreement conferred use immunity only, and the government did
    not use the immunized testimony).
    14
    that the district court did not clearly err in finding that if
    Short was granted use immunity, the government did not violate
    that agreement.     See United States v. Jones, 
    542 F.2d 186
    , 199
    (4th Cir. 1976) (findings of fact related to independence of
    evidence from immunized testimony will be overturned only if
    clearly erroneous), cert. denied, 
    426 U.S. 922
    (1976).
    Because   Short     never   had   transactional     immunity   and   the
    government   did   not   violate   any      purported   agreement   for   use
    immunity, we find no error in the district court’s denial of
    Short’s motion to dismiss.
    B.
    We next consider the district court’s denial of the motion
    to suppress.   In ruling on a motion to suppress, we review the
    district court’s legal conclusions de novo and its underlying
    factual findings for clear error.           United States v. Buckner, 
    473 F.3d 551
    , 553 (4th Cir. 2007).
    Short argues that the district court erred in finding that
    his wife consented to the search of his home.            He maintains that
    his wife’s consent was an involuntary acquiescence to a claim of
    lawful authority, given only after the official conducting the
    search asserted he would obtain a warrant, if necessary.              Thus,
    15
    he    contends     the    district    court      should    have    suppressed    the
    evidence obtained through the search of his home.
    In determining whether consent to search was freely and
    voluntarily given, we examine the totality of the circumstances
    surrounding the consent.             United States v. Lattimore, 
    87 F.3d 647
    , 650 (4th Cir. 1996) (en banc).                In viewing the totality of
    the     circumstances,       it      is   appropriate        to    consider      “the
    characteristics of the [person giving consent] (such as age,
    maturity, education, intelligence, and experience) as well as
    the conditions under which the consent to search was given (such
    as the officer’s conduct; the number of officers present; and
    the   duration,      location,     and    time    of   the    encounter).”       
    Id. Whether the
      person   giving    consent     knew    that    she   possessed   a
    right   to    refuse     consent   also   is     relevant    in   determining    the
    voluntariness       of    consent,    although      the     government    need   not
    demonstrate that the person giving consent knew of her right to
    refuse consent to prove that the consent was voluntary.                    
    Id. The district
    court determined that Ms. Short voluntarily
    consented to the search.           The district court found:
    Ms. Short did give consent.  She said it was okay to
    search.    She voluntarily and knowingly signed the
    consent to search form.
    The witness who testified -- Detective Smithley,
    I believe is his name -- was a very credible witness.
    He   didn’t   appear at   all  rude  or   forceful  or
    intimidating, and I specifically asked Ms. Short if
    16
    the officer was courteous to her, and she said, oh,
    yes, he was courteous.    There was nothing that was
    overpowering about this situation, and I would find as
    a fact that Ms. Short did okay the search, that she
    was an appropriate individual to consent to the
    search, she lived there, she was his wife, and that
    the search was appropriate without a warrant as a
    consent search.
    J.A. 274-75.
    Based    on     our    review     of    the   totality     of    the   surrounding
    circumstances, we cannot say that the factual finding of the
    district      court    that       Ms.   Short’s      consent     was     voluntary     was
    clearly erroneous.           On the date of the search, Ms. Short was 26
    years old, the mother of two children, and held employment with
    North End Cab Company.             Testimony also established that she had
    dealt with police officers before and been arrested on a number
    of   occasions.         Further,        Ms.    Short   admitted        to    signing   the
    consent form and not revoking that consent at any time during
    the search.         It is true that Ms. Short testified, on several
    occasions,      that        she   agreed      to    sign   the        document   because
    otherwise, she “and [her] kids [would have] to stand outside” in
    the cold while the police obtained a warrant. 4                         J.A. 182.      She
    also admitted, however, that she signed the consent form because
    4
    Strangely enough, after giving consent, Ms. Short
    testified that she and her step-daughter stayed outside on the
    porch while the officers searched the home. When asked why she
    stayed outside when her stated reason for signing the form was
    (Continued)
    17
    she “didn’t think at the time . . . there was anything to get in
    [her] house.”      J.A. 184-85.          Moreover, she explained that she
    found the police officer that asked for the consent “courteous.”
    J.A. 191.    Based on this record, the conclusion that Ms. Short’s
    oral consent was given voluntarily is amply supported; indeed,
    we may safely say that no other opinion is supportable.
    Nevertheless,     Short    argues       that     the    police       officer’s
    statement that he could apply for a warrant if Ms. Short denied
    consent invalidated the consent.              We disagree.         “The fact that a
    search warrant was mentioned does not necessarily constitute a
    coercive factor negating consent.”              United States v. Hummer, 
    916 F.2d 186
    , 190 (4th Cir. 1990) (internal quotations and citation
    omitted),    abrogated    on     other     grounds      by    United     States   v.
    Hairston, 
    96 F.3d 102
    , 106 (4th Cir. 1996).                     On the contrary,
    this   is   but   one   factor    to    consider      in     determining     whether
    voluntary consent was given, and can be negated if the person
    giving consent “is advised several times orally and in writing
    of [her] right to refuse the search.”                      Id.; see also United
    States v. Dennis, 
    625 F.2d 782
    , 793 (8th Cir. 1980) (finding
    voluntary   consent,     although      consent    was      given    after    officers
    informed defendant that they would seek a warrant if consent was
    so she would not be forced to stand outside, she answered, “I
    don’t know. But I just did.” J.A. 193.

    not   given);   United   States   v.    Drennen,    No.   96-4301,   
    1997 WL 543379
    , at *4 (4th Cir. Sept. 5, 1997) (same).              Here, Ms. Short
    was given a form that delineated her rights, and she was told
    orally by a police officer that she didn’t need to consent.                 In
    light of these circumstances, we find that the district court
    did not clearly err in finding that Ms. Smith gave informed,
    voluntary consent to search her home.              This is particularly so
    in light of the rule that when the lower court bases its ruling
    on oral testimony heard at a suppression hearing, such as is the
    case here, the ruling may not be disturbed “unless it can be
    said that the view of the evidence taken by the district court
    is implausible in light of the entire record.” 5              
    Lattimore, 87 F.3d at 651
    .
    5
    Short also argues that the evidence should have been
    suppressed because the search resulted from his unlawful arrest.
    See Wong Sun v. United States, 
    371 U.S. 471
    , 485 (1963) (finding
    that generally “evidence which derives . . . immediately from an
    unlawful entry and an unauthorized arrest . . . is . . . the
    ‘fruit’ of official illegality,” and should be suppressed). We
    disagree.   Not all evidence “is [the] ‘fruit of the poisonous
    tree’ simply because it would not have come to light but for the
    illegal actions of the police.”    
    Id. at 487-88.
      “Rather, the
    more apt question in such a case is ‘whether, granting
    establishment of the primary illegality, the evidence to which
    instant objection is made has been come at by exploitation of
    that illegality or instead by means sufficiently distinguishable
    to be purged of the primary taint.’”       
    Id. at 488
    (quoting
    Maguire, Evidence of Guilt, 221 (1959)).        Here, Short has
    proposed no explanation, and we see none, for how the search
    resulted from the purported unlawful arrest.      Thus, we find
    Short’s argument without merit.
    19
    C.
    Finally,      we    consider    the    district      court’s   determination
    that Short was subject to a mandatory minimum sentence of life
    imprisonment pursuant to 21 U.S.C. § 841(b)(1)(A).                         “We review
    de novo the district court’s interpretation of the statute and
    conclusion     that        [Short’s]     prior     convictions      were     predicate
    offenses under the statute.”             United States v. Hawkins, 
    548 F.3d 1143
    , 1149 (8th Cir. 2008).
    Section 841(b)(1)(A) provides that if any person commits a
    federal drug offense involving 50 grams or more of cocaine base
    “after two or more prior convictions for a felony drug offense
    have become final, such person shall be sentenced to a mandatory
    term    of    life        imprisonment       without      release.”        21   U.S.C.
    § 841(b)(1)(A).           Because the jury convicted Short of conspiracy
    to possess with intent to distribute cocaine base in excess of
    50 grams, and because Short was convicted in state court in
    March 2004 and December 2005 of two felony drug offenses, the
    district court found that an enhancement under § 841(b)(1)(A)
    was appropriate.
    Short argues that the district court erroneously relied on
    these two state convictions to enhance his sentence because the
    government had failed to establish that they were not part of
    the    same   conspiracy       charged       in   Count    1   of   the    superseding
    20
    indictment.       He reasons that these two convictions cannot be
    “prior felony drug offense[s]” for purposes of § 841(b)(1)(A)
    because they occurred while the charged conspiracy was taking
    place.     We disagree.
    We have squarely held that, for purposes of § 841(b)(1)(A),
    “[w]hen a defendant is convicted of a drug conspiracy under 21
    U.S.C. § 846, prior felony drug convictions that fall within the
    conspiracy       period   may    be     used   to   enhance       the    defendant’s
    sentence     if     the   conspiracy         continued     after        his     earlier
    convictions were final.”            United States v. Smith, 
    451 F.3d 209
    ,
    225-26 (4th Cir. 2006); see also United States v. Moore, 305 F.
    App’x     130,   134   (4th   Cir.    2008)    (finding    that    2000       and    2003
    convictions could be considered prior convictions for sentencing
    enhancement       purposes      where    conspiracy       began     in        1987    and
    continued through 2005).            Here, the charged conspiracy continued
    through 2007, and thus, we find no error in the district court’s
    use   of   Short’s     2004   and     2005   convictions    for     § 841(b)(1)(A)
    enhancement purposes. 6
    6
    Short also argues that the court erroneously applied the
    base offense level from section 2A1.1 in the U.S. Sentencing
    Guidelines.   Because he faced a statutory mandatory minimum
    sentence of life imprisonment, however, his guideline sentence
    was necessarily life imprisonment pursuant to section 5G1.1.
    See U.S.S.G. § 5G1.1(b) (“Where a statutorily required minimum
    sentence is greater than the maximum of the applicable guideline
    (Continued)
    21
    III.
    For the foregoing reasons, we
    AFFIRM.
    range, the statutorily required minimum sentence shall be the
    guideline sentence.”). The issue is thus moot.
