    confidential informant, who then turned the sample over
    to the Government. Mr. Bryant was subsequently

    distribute cocaine base. Mr. Bryant initially pleaded
    guilty to the charge, but later unsuccessfully sought to
    withdraw his guilty plea. At his sentencing hearing, the

    district court sentenced Mr. Bryant to 180 months’ impris-
    onment. Mr. Bryant now challenges the district court’s
    denial of his motion to withdraw his guilty plea. He
    also raises several challenges to the sentence imposed by
    the district court. For the reasons set forth in this opinion,
    we affirm the district court’s denial of his motion to
    withdraw his plea, vacate his sentence and remand for
    resentencing.
    I
    BACKGROUND
    A.
    In 2005, a confidential informant contacted Eddie Frank-
    lin and attempted to purchase crack cocaine. Franklin
    agreed to obtain crack for the informant and called the
    defendant, Thomas Bryant, in an attempt to procure the
    drugs. On April 8, 2005, Mr. Bryant provided Franklin
    with a substance that Franklin described as hard and rock-
    like. Franklin then delivered the substance to the infor-
    mant, who turned it over to Drug Enforcement Adminis-
    tration (“DEA”) agents.
    A DEA chemist analyzed the substance and, in his report,
    described it as a beige, compressed, moist powder. Al-
    though the substance tested positive for the presence of
    cocaine base, the chemist did not detect the presence of
    No. 07-3608                                                  3
    sodium bicarbonate in the substance.1 Later, a second
    DEA chemist analyzed the substance, described it as
    hard and rock-like and concluded that it contained
    sodium bicarbonate. After the second chemist completed
    his analysis, the Government discovered that he had
    mishandled evidence on several occasions during the
    time period in which he analyzed the substance at issue
    here. The Government decided that, because chain of
    custody issues may have resulted from the chemist’s
    mishandling of evidence, it would introduce neither the
    substance nor the second chemist’s report in its case
    against Mr. Bryant.
    B.
    Several months after Franklin delivered the substance
    to the informant, the Government arrested Mr. Bryant and
    Franklin. Mr. Bryant subsequently entered a blind condi-
    tional guilty plea to one count of conspiracy to distribute
    cocaine base; he reserved the issues of the type and quan-
    tity of the drugs involved for a bench trial. At the time
    of his plea, he was aware that the first DEA chemist’s
    description of the substance conflicted with Franklin’s
    description. He believed, however, that the second DEA
    chemist’s report would corroborate Franklin’s description
    1
    The presence of sodium bicarbonate in a mixture containing
    cocaine base is one of the indicators that the mixture is crack
    cocaine.
    4                                                   No. 07-3608
    of the substance.2 At the time of his plea, Mr. Bryant was
    unaware that the second chemist had mishandled evi-
    dence.
    On October 27, 2006, Mr. Bryant moved to withdraw
    his plea. He claimed that he had been pressured into
    accepting the plea by his former attorney, who had
    stated that he was unprepared for trial. Mr. Bryant did not
    claim that he was innocent of the crime charged; rather,
    he indicated that he did not believe that the Govern-
    ment could prove its case beyond a reasonable doubt.
    The district court held a plea withdrawal hearing, during
    which both Mr. Bryant and his former attorney testified.
    The district court noted that Mr. Bryant’s statements
    conflicted with his former attorney’s statements. It con-
    cluded that Mr. Bryant had intentionally misled the
    court and denied Mr. Bryant’s motion to withdraw his
    plea.
    Mr. Bryant asserts that, immediately prior to his
    bench trial, he made a second motion to withdraw his
    plea on the basis of newly discovered evidence.3 He con-
    2
    The first DEA chemist to analyze the substance described it
    as a beige, compressed, moist powder. Both the second DEA
    chemist and Franklin described the substance as hard and rock-
    like.
    3
    The Government contends that Mr. Bryant did not move to
    withdraw his plea; rather, it claims, he requested additional
    time “to figure it out and determine whether it matters.” R.183-9
    at 6. The Government characterizes Mr. Bryant’s statements
    (continued...)
    No. 07-3608                                                     5
    tended that he should be allowed to withdraw his plea
    on the ground of newly discovered evidence in light of the
    Government’s discovery that the second chemist had
    mishandled evidence and its decision that it would not
    introduce the substance or the second DEA chemist’s
    report. The district court rejected this argument. It con-
    cluded that Mr. Bryant would not have altered his
    decision had he known that the second chemist mishan-
    dled evidence because Mr. Bryant “necessarily challenged
    [the chemist’s] finding by saying he wasn’t going to
    agree that it was crack.” R.183-9 at 17.
    On August 3, 2007, the district court held a bench trial
    to determine the type and quantity of drugs involved in
    the conspiracy.4 Franklin testified that he had purchased
    3
    (...continued)
    as an emergency motion to continue the bench trial. Statements
    made by the district court support this characterization. R.183-9
    at 18 (“I’m not going to continue [the trial], not for that rea-
    son.”).
    Although Mr. Bryant claims to have made a motion to
    withdraw his plea, there is no indication that he expressly
    requested that his plea be withdrawn. Nevertheless, because
    Mr. Bryant asserted that he should have “known about [the
    evidentiary problems] so [he] could have figured this out
    while [he] still had time,” id. at 6, we shall assume, for the
    purposes of this appeal, that Mr. Bryant moved to withdraw
    his plea.
    4
    The issue of the type and quantity of drugs involved in the
    charged crime was litigated on two occasions in the pro-
    ceedings before the district court: First, in order to determine
    (continued...)

    crack from Mr. Bryant on numerous occasions. He re-
    counted the details of the April 8 transaction, stating that
    he received about sixty-three grams of crack cocaine
    from Mr. Bryant. He described the substance he received

    the statutory maximum sentence, the court held a bench trial to
    determine whether the Government had proven, beyond a
    reasonable doubt, that Mr. Bryant had conspired to distribute
    five kilograms or more of a mixture containing cocaine or fifty
    grams or more of a mixture containing cocaine base. 
    21 U.S.C. § 846
     (“Any person who attempts or conspires to commit any
    offense defined in this subchapter shall be subject to the same
    penalties as those prescribed for the offense, the commission
    of which was the object of the attempt or conspiracy.”); 
    21 U.S.C. §§ 841
    (b)(1)(A)-(C) (establishing statutory maximum
    and minimum sentences for the crime of possession with
    intent to distribute a controlled substance). As we previously
    have noted, “all facts . . . that set the maximum possible punish-
    ment under § 841(b) must be established beyond a reasonable
    doubt to the satisfaction of the same body that determines
    culpability under § 841(a).” United States v. Brough, 
    243 F.3d 1078
    , 1079 (7th Cir. 2001) (citing United States v. Nance, 
    236 F.3d 820
     (7th Cir. 2000)). Next, the district court held a sentenc-
    ing hearing to determine the type and quantity of the drugs
    involved in the charged conspiracy; at that hearing, “[t]he
    government [had] the burden of proving the quantity of drugs
    attributable to [the] defendant for sentencing purposes by a
    preponderance of the evidence.” United States v. Krasinski,
    
    545 F.3d 546
    , 551 (7th Cir. 2008) (citing United States v. Soto-
    Piedra, 
    525 F.3d 527
    , 529 (7th Cir. 2008)).
    No. 07-3608                                                  7
    on that date as hard and rock-like.5 The district court
    concluded, based on the discrepancy between the first
    DEA chemist’s description of the substance and
    Franklin’s description of the substance, that the Govern-
    ment had failed to prove, beyond a reasonable doubt, that
    Mr. Bryant had conspired to distribute crack cocaine.
    R.144.
    At Mr. Bryant’s sentencing hearing, the district court
    found, based on the testimony presented at the bench
    trial, 6 that the Government had proven, by a preponderance
    of the evidence, that Mr. Bryant had conspired to
    distribute more than fifty grams of crack cocaine. The
    court therefore assigned Mr. Bryant a base offense level
    of 30 under the November 2007 Amendments to the
    Sentencing Guidelines.7 The district court next applied a
    two-level enhancement for obstruction of justice based
    5
    Although Franklin could recall the details of the April 8
    transaction with specificity, he was unable to provide specific
    information about the amounts of drugs involved in any of his
    prior transactions with Mr. Bryant or the dates on which
    those transactions took place. Nor could he estimate the num-
    ber of times he had purchased drugs from Mr. Bryant.
    6
    The Government presented no new evidence at the sen-
    tencing hearing.
    7
    Although the November 2007 Amendments were not in
    effect at the time Mr. Bryant was sentenced, the district court
    agreed, pursuant to Mr. Bryant’s request, to sentence him
    under the November 2007 Amendments. The November 2007
    Amendments partially ameliorated the sentencing disparity
    between crack and powder cocaine.
    8                                              No. 07-3608
    on its finding that Mr. Bryant intentionally had made
    material misrepresentations to the court during his first
    plea withdrawal hearing. It then denied Mr. Bryant’s
    motion for a two-level reduction in offense level for
    acceptance of responsibility. As a result of these enhance-
    ments, the court determined that Mr. Bryant’s offense
    level was 32.
    Next, the district court assigned a criminal history
    category of IV to Mr. Bryant, based, in part, upon a state-
    court conviction for cocaine possession. Mr. Bryant
    claimed, however, that the conviction should not be
    considered for the purpose of determining his criminal
    history category; instead, he submitted, the conviction
    should be considered relevant conduct for sentencing
    purposes because the conviction involved similar
    conduct that had taken place during the time period of
    the conspiracy. The district court declined to deem the
    conviction relevant conduct.
    The district court sentenced Mr. Bryant to 180 months’
    imprisonment, a sentence in the middle of the advisory
    guideline range for an individual of Mr. Bryant’s criminal
    history category and offense level. Because Mr. Bryant
    was sentenced before the Supreme Court’s decision in
    Kimbrough v. United States, ___ U.S. ___, 
    128 S. Ct. 558
    (2007), the district court did not take the sentencing
    disparity between crack and powder cocaine into
    account when determining Mr. Bryant’s sentence.
    Mr. Bryant subsequently filed this appeal.

    II
    DISCUSSION
    Mr. Bryant raises the following arguments: (1) the
    district court abused its discretion in denying his second
    motion to withdraw his plea; (2) the district court clearly
    erred in finding that the Government had proven, by a
    preponderance of the evidence, that the charged con-
    spiracy involved crack cocaine; (3) the district court
    clearly erred in applying a two-level enhancement for
    obstruction of justice based on the statements he made
    at his first plea withdrawal hearing; (4) the district court
    clearly erred in declining to apply a two-level reduction
    for acceptance of responsibility; (5) the district court
    clearly erred by increasing his criminal history score
    because of his state-court conviction for possession of
    cocaine base; and (6) his sentence should be vacated
    and remanded for resentencing in light of the Supreme
    Court’s opinion in Kimbrough, 
    128 S. Ct. 558
    . We shall
    address each of these arguments in turn.
    A.
    Mr. Bryant contends that the district court erred in
    denying his second motion to withdraw his guilty plea.
    We review a district court’s denial of a motion to with-
    draw a plea for abuse of discretion. United States v. Silva,
    
    122 F.3d 412
    , 414-15 (7th Cir. 1997). After a district court
    accepts a defendant’s guilty plea and before it imposes
    a sentence, the court may permit the defendant to with-
    draw his plea provided that he “can show a fair and
    10                                                  No. 07-3608
    just reason for requesting the withdrawal.” Fed. R.
    Crim. P. 11(d)(2)(B); accord United States v. Underwood, 
    174 F.3d 850
    , 852 (7th Cir. 1999). The defendant bears the
    burden of proving that a fair and just reason for with-
    drawal exists. United States v. Coonce, 
    961 F.2d 1268
    , 1275
    (7th Cir. 1992).
    Mr. Bryant claims that, immediately prior to his bench
    trial, he discovered new evidence that undermined the
    Government’s case against him: He learned that the
    second DEA chemist had mishandled drug samples
    during the time period in which he evaluated the sub-
    stance at issue in Mr. Bryant’s case, and that the Gov-
    ernment no longer intended to introduce the second
    chemist’s report or the substance itself into evidence.
    Mr. Bryant contends that because he discovered new,
    relevant evidence after entering his plea, see, e.g., United
    States v. Garcia, 
    401 F.3d 1008
    , 1011 (9th Cir. 2005), and
    because the discovery of that evidence enabled him to
    make a legal argument that he was unaware of at the time
    of his plea, see, e.g., United States v. Groll, 
    992 F.2d 755
    , 759-
    60 (7th Cir. 1993), he has demonstrated a fair and just
    reason to withdraw his plea.
    We cannot say that the district court abused its discre-
    tion in denying this motion. Unlike the defendant in
    Garcia, Mr. Bryant did not present newly discovered
    evidence relating to his factual guilt or innocence. Garcia,
    
    401 F.3d at 1011-12
     (concluding that the defendant’s
    discovery of a new witness created a fair and just reason
    for withdrawal of the defendant’s guilty plea because the
    witness’ statement “raise[d] new questions about [the
    No. 07-3608                                               11
    defendant’s] involvement in the illegal activity”). Addi-
    tionally, unlike the defendant in Groll, Mr. Bryant did not
    introduce evidence that, at the time of his plea, he was
    unaware of a legal defense to the crime charged. Groll, 
    992 F.2d at 758, 759-60
     (stating that “being legally innocent of
    the crime is a fair and just reason to withdraw a guilty
    plea” and concluding that the district court abused its
    discretion in denying the defendant’s motion to with-
    draw her guilty plea when unrebutted evidence in the
    record could have supported her entrapment defense
    and the defendant may have been unaware of the en-
    trapment defense at the time she pleaded guilty).
    The evidence and legal arguments that Mr. Bryant relied
    upon in his motion at best relate to the strength of the
    Government’s case against him, not his factual or legal
    innocence. As we previously have noted, “[a] defendant
    is not entitled to withdraw his plea merely because he
    has misapprehended the strength of the government’s
    case.” Silva, 
    122 F.3d at 415
    . When a defendant has been
    apprised of the facts giving rise to the charges against
    him, the mere fact that he does not know, at the time of
    his plea, what evidence the Government will use against
    him does not present a “fair and just” reason for him to
    withdraw his plea. See Underwood, 
    174 F.3d at 853-54
    (concluding that “[the defendant’s] reevaluation of his
    trial prospects afforded no basis for withdrawing his
    validly-entered guilty pleas”); United States v. Seybold, 
    979 F.2d 582
    , 587 (7th Cir. 1992) (noting that Rule 11 “does not
    require the trial judge at the plea hearing to air all of the
    government’s evidence”). Furthermore, it is far from
    clear that Mr. Bryant’s discovery of the problem with one
    12                                              No. 07-3608
    of the Government’s chemists would have impacted his
    decision to plead guilty. Although Mr. Bryant pleaded
    guilty to the charged conspiracy, he specifically reserved
    for a bench trial the issues of the type and quantity of
    drugs involved in the conspiracy. In other words, he
    admitted to conspiring to possess and distribute drugs;
    he did not admit that the drugs he conspired to distrib-
    ute included cocaine or cocaine base. The discovery of
    the chemist’s mishandling of the evidence, however,
    relates solely to the issue of the type of drugs involved in
    the conspiracy, and is irrelevant to the question of whether
    Mr. Bryant conspired to distribute any controlled sub-
    stance. As the district court noted, Mr. Bryant “necessarily
    challenged [the second chemist’s] finding by saying he
    wasn’t going to agree that [the substance] was crack.”
    R.183-9 at 17. We therefore cannot say that the district
    court abused its discretion in rejecting Mr. Bryant’s
    motion to withdraw his plea.
    B.
    1.
    Mr. Bryant raises a number of challenges to the sen-
    tence imposed by the district court. Among his other
    arguments, Mr. Bryant contends, and the Government
    concedes, that his sentence should be vacated and re-
    manded in light of the Supreme Court’s decision in
    Kimbrough v. United States, ___ U.S. ___, 
    128 S. Ct. 558
    (2007). We agree with the parties that Mr. Bryant
    preserved this issue. During the sentencing hearing,
    which was held before the Supreme Court’s decision in
    No. 07-3608                                                13
    Kimbrough, Mr. Bryant maintained that the drugs involved
    in the conspiracy were not crack cocaine. As we held in
    United States v. Padilla, 
    520 F.3d 766
    , 774 (7th Cir. 2008),
    such a position is sufficient to preserve the Kimbrough
    issue. Accordingly, we vacate Mr. Bryant’s sentence and
    remand for resentencing so that the district court may
    take into account the sentencing disparity between crack
    and powder cocaine when sentencing Mr. Bryant. We
    now turn to the remainder of Mr. Bryant’s challenges to
    his sentence.
    2.
    Mr. Bryant challenges the district court’s conclusion
    that the charged conspiracy involved crack cocaine. We
    review the district court’s finding for clear error, United
    States v. Wilson, 
    437 F.3d 616
    , 621 (7th Cir. 2006), and shall
    reverse its decision “only if we are left with the definite
    and firm conviction that a mistake was made.” Padilla,
    
    520 F.3d at 769
    .
    The Government was required to prove, by a prepon-
    derance of the evidence, that the charged conspiracy
    involved “crack” cocaine. United States v. Johnson, 
    200 F.3d 529
    , 537 (2000). Mr. Bryant claims that the Govern-
    ment’s evidence on this issue, which consisted solely of
    the evidence presented at the bench trial, was insufficient
    to support the district court’s finding. In particular,
    Mr. Bryant claims that Franklin’s testimony was unreli-
    able because, with the exception of the April 8 transaction,
    Franklin was unable to recall the details of any of the
    transactions in which he allegedly received crack cocaine
    14                                               No. 07-3608
    from Mr. Bryant. Mr. Bryant describes Franklin’s testi-
    mony as an allegation “that, at some point in the past,
    though he doesn’t remember exactly when, [Franklin]
    received some amount of crack cocaine [from Mr. Bryant],
    though he doesn’t remember how much,” and asserts
    that this vague testimony cannot support a finding that
    Mr. Bryant conspired to distribute more than fifty grams
    of crack cocaine. Appellant’s Br. 28.
    Although Franklin’s testimony lacked specific details
    about the transactions in which he had obtained crack
    cocaine, it nevertheless contained sufficient details to
    support the district court’s conclusion. Franklin was not
    able to recall the dates on which he received crack cocaine
    from Mr. Bryant or the specific quantities of crack cocaine
    he received. However, he did testify that each of the
    transactions involved more than sixty-three grams of
    crack cocaine. In addition, he provided detailed testi-
    mony about an occasion when he watched Mr. Bryant
    “cook” powder cocaine into crack cocaine. Further-
    more, Franklin’s testimony was not the only evidence
    presented to the district court on this issue; the Govern-
    ment introduced recorded conversations between
    Franklin and the informant, in which those two
    individuals discussed having Franklin’s supplier “cook”
    the cocaine. It also introduced evidence that the sub-
    stance that Franklin received on April 8 contained cocaine
    base. The district court was entitled to rely on this evi-
    dence, in its totality, in determining that the conspiracy
    involved crack cocaine. See, e.g., Padilla, 
    520 F.3d at 770-71
    (noting that “the government can prove a substance is
    crack by offering testimony from people familiar with the
    No. 07-3608                                              15
    drug, United States v. Anderson, 
    450 F.3d 294
    , 301 (7th Cir.
    2006), including . . . an informant’s belief that he was
    purchasing crack”); United States v. Earnest, 
    185 F.3d 808
    ,
    813 (7th Cir. 1999) (recognizing that a court may rely on
    the testimony of experts and other witnesses in con-
    cluding that a substance is crack cocaine).
    Mr. Bryant also suggests that, because the Government
    could not show that the substance contained sodium
    bicarbonate, it failed to prove, by a preponderance of the
    evidence, that the substance was crack cocaine. The
    Sentencing Guidelines distinguish between “cocaine base”
    and “cocaine” for sentencing purposes. U.S.S.G. § 2D1.1(c)
    (“Drug Quantity Table”). Although “greater punishment
    applies to cocaine base than to cocaine,” Lemon v. United
    States, 
    335 F.3d 1095
    , 1095 (8th Cir. 2003), the Sentencing
    Guidelines did not define “cocaine base” until the Guide-
    lines were amended in 1993. United States v. Waters, 
    313 F.3d 151
    , 155 (3d Cir. 2002). “Prior to 1993, circuit courts
    were divided over whether ‘cocaine base’ under § 2D1.1
    included only ‘crack,’ or whether it also broadly encom-
    passed all other substances the scientific community
    generally considered to be cocaine base.” United States v.
    Abdul, 
    122 F.3d 477
    , 478 (7th Cir. 1997) (citations omitted)
    (discussing the conflicting definitions of cocaine base
    adopted by various courts). To resolve the conflict, the
    Sentencing Commission proposed an amendment to
    Section 2D1.1(c). 
    Id.
     The amendment, which became
    effective in 1993, 
    id. at 479
    , reads as follows:
    “Cocaine base,” for the purposes of [the Sentencing
    Guidelines], means “crack.” “Crack” is the street name
    16                                                  No. 07-3608
    for a form of cocaine base, usually prepared by pro-
    cessing cocaine hydrochloride and sodium bicarbonate,
    and usually appearing in a lumpy, rocklike form.
    U.S.S.G. § 2D1.1(c) note (D) (hereinafter “Note D”).8
    Although “the definition of ‘cocaine base’ in the Guide-
    lines makes it clear that only the ‘crack’ form of cocaine
    base should receive the . . . sentencing enhancement
    under § 2D1.1,” United States v. Jones, 
    159 F.3d 969
    , 982
    (6th Cir. 1998), the Guidelines do not explicitly define
    “crack” in terms of its chemical composition, method of
    manufacture or physical appearance. See Waters, 
    313 F.3d at 156
     (noting that “there is no precise chemical
    definition of crack cocaine,” and concluding that “crack
    generally refers more to the way the drug is prepared
    and used than the specific chemical composition”).
    Perhaps due to the reference to sodium bicarbonate in
    Note D and the absence of a specific definition of “crack,”
    it has become common for individuals sentenced under
    Section 2D1.1 to challenge whether a substance is, in
    fact, crack cocaine. Often, as in the case before this
    court, these challenges take the form of claims that the
    substance at issue cannot be crack cocaine because it
    does not contain sodium bicarbonate. See, e.g., Abdul, 
    122 F.3d at 478
    . We have rejected this argument. We have

    “Notes or commentary to the sentencing guidelines are

    Constitution or a federal statute, or clearly inconsistent with
    the guideline[s].” United States v. Brooks,

    held that, based on the use of the qualifying term “usu-
    ally” in Note D, “crack” is not limited to cocaine that has
    been processed with sodium bicarbonate. See id. at 479
    (“If courts were to disregard the qualifying term ‘usually,’
    crack dealers could avoid the penalties for distribution
    of crack by merely finding some substitute for baking
    soda in production, or by crushing the rocks so that
    the final product resembles powder.”). Other courts
    have reached similar conclusions. See United States v.
    Whitehead, 
    487 F.3d 1068
    , 1072 (8th Cir. 2007) (“[T]he
    government need not show the presence of sodium bicar-
    bonate in order to prove that cocaine is crack. . . .”);

    , 1022 (D.C. Cir. 2004)
    (“The Sentencing Guidelines do not insist that crack can
    be made only with sodium bicarbonate; they merely
    state that it is ‘usually prepared’ that way.” (internal
    citation omitted)); Waters, 
    313 F.3d at 155
     (“[I]t is not
    necessary for the government to show that a substance
    contains sodium bicarbonate in order to demonstrate by
    a preponderance of the evidence that the drugs in ques-

    161 F.3d 1240
    , 1248 (10th Cir. 1998) (“We interpret the qualifier
    ‘usually’ . . . as an acknowledgment that other methods
    of crack preparation exist and that not all forms of
    ‘cocaine base’ need contain sodium bicarbonate to
    qualify as crack for sentencing purposes. Indeed, it
    appears that the method which uses sodium bicarbonate
    is the least sophisticated and yields the lowest purity.”
    (internal quotation marks and citations omitted)); Jones,

    Our approach takes into account the fact that there are
    multiple methods of manufacturing crack cocaine. Indeed,
    we have stated expressly that “while crack might gen-
    erally be produced using sodium bicarbonate, production
    with sodium bicarbonate is not the exclusive preparation
    method recognized for the purposes of § 2D1.1(c).” Abdul,
    
    122 F.3d at 479
    . Two of our sister circuits have
    recognized that chemical compounds other than sodium
    bicarbonate, including sodium borate and niacinamide,
    may be used to convert powder cocaine into crack cocaine.9
    Furthermore, at least one expert has opined that, even
    where sodium bicarbonate is utilized to process powder
    cocaine into crack, the final product may not necessarily
    contain detectable quantities of sodium bicarbonate.

    “conclud[ing] that the presence of sodium borate did not

    in part, on an expert’s testimony that he: (1) had converted
    powder cocaine to crack using sodium borate; (2) had previously
    detected sodium borate in other crack samples; and (3) was
    aware that other chemists had detected sodium borate in
    crack samples); United States v. Waters,

    of sodium bicarbonate and powdered cocaine . . . you
    should have no sodium bicarbonate left when the con-
    version is complete. However, traditionally, what we
    find is that out on the street an excess of this bicarbonate
    is used in the conversion.” (internal quotation marks and
    citations omitted)).
    Cases from this and other circuits establish, therefore,
    that the presence of sodium bicarbonate is not a litmus test
    for establishing that a substance is “crack” for the pur-
    poses of Section 2D1.1. Instead, courts have considered
    the following factors, among others, in determining
    whether a substance qualifies as crack for sentencing
    purposes: (1) whether “the substance at issue [has] tested
    positive for the presence of cocaine base”;1 0 (2) the color
    of the substance;11 (3) the shape and texture of the sub-
    stance;12 (4) the method of packaging;1 3 (5) the price of the

    Crack is not defined merely by its secondary ingredients;

    in that market, disastrous effects for both those who

    Although there is little legislative history discussing the
    reasoning behind the sentencing disparity between crack and
    powder cocaine, Congress’ concern for the impact that crack
    would have on individuals and communities is clear. See, e.g.,
    132 Cong. Rec. 26,447 (1986) (statement of Sen. Chiles) (“The
    whole Nation now knows about crack cocaine. They know it
    can be [bought] for the price of a cassette tape, and make

    Sen. Chiles) (“Crack is available to the young, and it will be in
    the schools this fall. . . . We have all heard of cocaine, but I must
    stress to you that crack cocaine is something altogether dif-
    ferent. It is more powerful; it is cheaper to use; it is also far
    more addictive. Crack cocaine is a purified form of powdered
    cocaine that is smoked. A hit of crack costs around $10, well
    within the budget of any teenager. When smoked, crack reaches
    the brain in less than 10 seconds. It produces a short but
    incredibly powerful high that is followed by an equally power-
    ful low.”).

    rely on a number of factors, including those we have
    discussed, in determining whether a substance is crack. We
    restate our earlier conclusion that the Government need
    not prove that a substance contains sodium bicarbonate
    in order to establish, for the purposes of Section 2D1.1, that
    a substance is crack. Accordingly, we cannot say that
    the district court clearly erred in determining that
    Mr. Bryant conspired to distribute more than fifty grams
    of crack cocaine.
    3.
    The district court concluded that Mr. Bryant made
    material misrepresentations during his first plea with-
    drawal hearing, in which he claimed that he was pres-
    sured into pleading guilty and that his former attorney
    told him that he was unprepared for trial. Therefore, the
    district court imposed a two-level enhancement for ob-
    struction of justice under Section 3C1.1 of the Sentencing
    Guidelines. U.S.S.G. § 3C1.1. We review for clear error
    the district court’s factual finding underlying the decision
    to impose the enhancement. United States v. Griffin,
    
    310 F.3d 1017
    , 1022 (7th Cir. 2002).
    An obstruction of justice enhancement may be imposed
    when a defendant has “willfully obstructed or impeded, or
    attempted to obstruct or impede, the administration of
    justice with respect to the investigation, prosecution, or
    sentencing of the instant offense of conviction.” U.S.S.G.
    § 3C1.1. The obstructive conduct must be related to the
    “offense of conviction and any relevant conduct” or a
    “closely related offense.” Id. “Committing, suborning, or
    No. 07-3608                                               23
    attempting to suborn perjury supports an obstruction
    enhancement.” Griffin, 
    310 F.3d at
    1023 (citing U.S.S.G.
    § 3C1.1 cmt. n.4(b)). “In order to find obstruction based
    on perjury, the sentencing court must find that the defen-
    dant willfully made misrepresentations under oath that
    were relevant to the prosecution, and specifically in-
    tended to obstruct justice.” United States v. Carroll, 
    412 F.3d 787
    , 793 (7th Cir. 2005) (citing United States v.
    Dunnigan, 
    507 U.S. 87
    , 94 (1993)).
    Mr. Bryant claims that the Government failed to demon-
    strate that he made false representations with the intent
    to obstruct justice. Although he admits that the state-
    ments he made at the plea withdrawal hearing conflicted
    with his former attorney’s testimony, he claims that the
    statements were an honest, though perhaps inaccurate,
    recollection of his discussions with his attorney. He
    asserts that his statements were not the result of a specific
    intent to obstruct justice, but, rather, were the product
    of his own misunderstanding and faulty memory.
    The district court explicitly addressed the willfulness of
    Mr. Bryant’s statements. It rejected his claim that he
    lacked specific intent to mislead the court:
    It wasn’t that . . . [Mr. Bryant] perceived that [his
    attorney] wasn’t prepared. The statements under oath
    were that Mr. Willis told him he had to plead
    guilty. . . . [T]here was nothing there about perception.
    It was actual statements.
    R.183-11 at 3. The district court concluded, based on its
    observation of Mr. Bryant and his former attorney—the
    24                                                  No. 07-3608
    only witnesses to testify at the plea withdrawal hear-
    ing—that Mr. Bryant “lied in his testimony.” R.183-8 at 12.
    The district court was entitled to make this conclusion. The
    district court simply based its determination that
    Mr. Bryant had perjured himself on its evaluation of the
    sworn statements of Mr. Bryant and his former attorney.
    We cannot say that the court clearly erred in reaching
    its conclusion.
    4.
    The district court also determined that Mr. Bryant was
    not entitled to a two-level reduction for acceptance of
    responsibility. The Guidelines permit district courts to
    apply a two-level reduction when a defendant “clearly
    demonstrates acceptance of responsibility for his offense.”
    U.S.S.G. § 3E1.1(a). The district court concluded, based
    on Mr. Bryant’s statements at his first plea withdrawal
    hearing, that Mr. Bryant was not entitled to the two-
    level reduction.
    The Government submits that the district court’s con-
    clusion was correct; it notes that conduct resulting in an
    obstruction of justice enhancement “ordinarily indicates
    that the defendant has not accepted responsibility for his
    criminal conduct.” U.S.S.G. § 3E1.1 cmt. n.4.1 6 In the Gov-
    16
    Accord United States v. Martinez, 
    169 F.3d 1049
    , 1056 (7th Cir.
    1999) (“Where a defendant falsely denies [ ] relevant conduct
    that the court determines to be true, he has acted in a manner
    (continued...)
    No. 07-3608                                                  25
    ernment’s view, this is not the type of extraordinary case
    where both an obstruction of justice enhancement and
    an acceptance of responsibility reduction are warranted.
    On the basis of this record, the district court reasonably
    could have determined that Mr. Bryant had not accepted
    responsibility for his conduct. Nevertheless, a statement
    made by the district court in the course of its proceedings
    gives us pause: The district court indicated that, because
    of Mr. Bryant’s statements at his first plea withdrawal
    hearing, “there was obstruction, and, you know, it was [a]
    very foolish thing to do because legally that means
    there’s no acceptance of responsibility.” R.183-8 at 13.
    However, the district court later recognized that “there
    are exceptions where somebody may have obstructed
    justice and could be allowed to accept responsibility.”
    R.183-11 at 6.
    It is clear that, while a finding that a defendant ob-
    structed justice “ordinarily indicates that the defendant
    has not accepted responsibility for his criminal conduct,”
    U.S.S.G. § 3E1.1 cmt. n.4 (emphasis added), the ap-
    plication of an obstruction of justice enhancement does not
    necessitate the denial of a reduction in offense level for
    acceptance of responsibility. See, e.g., United States v. Davis,
    
    442 F.3d 1003
    , 1009-10 (7th Cir. 2006) (“A defendant
    whose sentence was properly enhanced for obstruction
    16
    (...continued)
    inconsistent with the acceptance of responsibility, and the
    district court may refuse to grant this reduction.” (internal
    citations and quotation marks omitted)).
    26                                              No. 07-3608
    of justice is presumed not to have accepted responsibil-
    ity. . . . It is only under exceptional circumstances that a
    defendant who has received a sentence enhancement for
    obstruction of justice will be given a downward adjust-
    ment for acceptance [of] responsibility.” (internal citations
    omitted)). Because we remand Mr. Bryant’s sentence on
    other grounds, we need not determine whether the
    district court clearly erred in denying Mr. Bryant an
    acceptance of responsibility adjustment. The district
    court will have the opportunity to revisit this issue on
    remand.
    5.
    The parties agree that, during the relevant time period,
    Mr. Bryant pleaded guilty in Illinois state court to simple
    possession of less than fifteen grams of cocaine. At his
    sentencing hearing, Mr. Bryant argued that the state-
    court conviction should not be considered when calculat-
    ing his criminal history category; instead, he maintained
    that it should be considered as relevant conduct for
    sentencing purposes, because the conduct giving rise to
    the conviction involved possession of distribution-level
    quantities of cocaine during the conspiratorial time
    period. In the district court, the Government disagreed
    with Mr. Bryant’s contention: It asserted that the state-
    court conviction should not be considered relevant
    conduct because Mr. Bryant pleaded guilty to mere
    possession of, and not distribution of, cocaine. The Gov-
    ernment also claimed that there was insufficient evidence
    for the court to find that the conduct underlying the
    No. 07-3608                                              27
    conviction was related to the charged conspiracy. In its
    argument, the Government suggested that the court
    could not use the information in the police reports and
    charging documents to determine whether the state-
    court conviction should be considered relevant conduct.
    R.183-11 at 10. On appeal, however, the Government now
    concedes that “the district court could have found that
    the . . . state case constituted relevant conduct.” Govern-
    ment’s Br. 35.
    The district court rejected Mr. Bryant’s claim that the
    conviction should be considered relevant conduct, con-
    cluding that it “[did not] have enough information to
    say that [the conviction was] part of th[e] conspiracy.”
    R.183-11 at 15. Consequently, the court assigned Mr.
    Bryant a criminal history level of IV.1 7
    When calculating a defendant’s criminal history cate-
    gory, a district court may not consider prior convictions
    for acts which constitute relevant conduct—conduct that
    was part of the instant offense. U.S.S.G. § 4A1.2 cmt. n.1.
    Whether a prior conviction may be considered relevant
    conduct depends on the acts which gave rise to the con-
    viction; as we have noted, the name of the offense to which
    a defendant pleaded guilty “cannot be the basis of the
    district court’s [relevant conduct] determination, for . . .
    the sentencing guidelines direct courts to look to the
    underlying conduct of the offense, and not the name of
    17
    The parties agree that, had the conviction been considered
    relevant conduct, Mr. Bryant would have been assigned a
    criminal history category of III.

    U.S.S.G. §§ 4A1.2, 4A1.2 cmt. n.1 (noting that, for the
    purpose of computing the defendant’s criminal history
    level, a “prior sentence [is] any sentence . . . for conduct not
    part of the instant offense,” as specified in Section 1B1.3
    (emphasis added)); U.S.S.G. § 1B1.3(a)(2) (stating that
    relevant conduct includes “all acts and omissions . . . that
    were part of the same course of conduct or common
    scheme or plan as the offense of conviction” (emphasis
    added)). Therefore, the district court must consider the
    acts giving rise to Mr. Bryant’s state-court conviction and
    evaluate whether those acts and the charged conspiracy
    were either “part of a single episode, spree, or ongoing
    series of offenses,” or “substantially connected to each
    other by . . . [a] common factor, such as common victims,
    common accomplices, common purpose, or similar
    modus operandi.” U.S.S.G. § 1B1.3 cmt. n.9. Where the
    conduct underlying a prior conviction is unclear, the
    district court must “make specific factual findings re-
    garding the underlying conduct . . . thereby clearly pro-
    viding the basis for its ultimate resolution of the
    relevant conduct question.” Olson,

    consider the underlying police reports and charging
    documents in its relevant-conduct analysis. Certain
    statements indicate that the district court believed that
    it could consider only the conduct to which Mr. Bryant
    ultimately pleaded guilty in its relevant-conduct analysis.1 8
    Other statements, however, indicate that the district
    court simply did not have enough information to deter-
    mine whether the conduct underlying the conviction
    was relevant to the charged conspiracy.1 9 On remand, the
    district court will have the opportunity to further explain
    its reasoning and to conduct any fact-finding necessary
    to resolve this issue.
    Conclusion
    In sum, we hold that the evidence of the DEA chemist’s
    mishandling of evidence related solely to the strength of
    the Government’s case and did not present a fair and
    just reason for Mr. Bryant to withdraw his guilty plea.
    Therefore, the district court did not abuse its discretion
    in rejecting Mr. Bryant’s motion to withdraw his guilty
    plea. Furthermore, we conclude that the district court
    appropriately addressed the issues of whether the

    See, e.g., R.183-11 at 14-15 (“I think if the government tried
    to say this was delivery of a controlled substance, you would
    be well within your rights to come back and say, ‘Wait a
    minute. He pled guilty to possession, and that’s all you can
    do,’ so if it made a difference.”).

    charged conspiracy involved crack cocaine and whether
    an obstruction of justice enhancement was appropriate.
    Nevertheless, we vacate Mr. Bryant’s sentence and remand
    for resentencing so that the district court may take into
    account the sentencing disparity between crack and
    powder cocaine when sentencing Mr. Bryant. On
    remand, the district court will also have the opportunity to
    address fully whether Mr. Bryant is entitled to an accep-
    tance of responsibility adjustment and whether Mr.
    Bryant’s state-court conviction for possession of cocaine
    constitutes relevant conduct for sentencing purposes.
    Therefore, Mr. Bryant’s conviction is affirmed, but his
    sentence is vacated and his case is remanded to the
    district court for resentencing.
