    OPINION
    _________________
    ALICE M. BATCHELDER, Circuit Judge. Defendant-Appellant Chris Robinson appeals
    his conviction and sentence for conspiracy to distribute five kilograms or more of cocaine, in
    violation of 21 U.S.C. §§ 841(b)(1)(A) and 846. Robinson argues that: (1) the district court
    erroneously instructed the jury to determine the quantity of cocaine “involved in the conspiracy”
    instead of the quantity individually attributable to him; (2) the district court failed to charge a
    violation of 21 U.S.C. § 841(b)(1)(C) as a lesser-included offense; (3) the evidence was insufficient
    to prove his participation in a conspiracy; and (4) there was a prejudicial variance between the
    indictment and the proof at trial. Finding no merit in any of these contentions, we AFFIRM.
    I. BACKGROUND
    A grand jury indicted Robinson for his role in a conspiracy to distribute five or more
    kilograms of cocaine in the Eastern District of Tennessee from December 2003 through March 2006.
    At trial, the primary evidence against Robinson consisted of alleged co-conspirator Juan Valentin’s
    testimony and a series of recorded telephone conversations between Valentin and Robinson that
    1
    No. 07-5474              United States v. Robinson                                                          Page 2
    DEA officers intercepted from Valentin’s cell phone over a period of 88 days, beginning on May
    5, 2005.
    Valentin testified that beginning in December 2003, he developed “a business relationship”
    with Robinson in which the two of them worked together to sell cocaine. According to Valentin,
    he sold cocaine to Robinson “once or twice a week” in various quantities, sometimes on credit. The
    quantity he most frequently sold to Robinson was four-and-a-half ounces, which Valentin described
    as a “regular,” and the largest single quantity exchanged between them was half a kilogram. Besides
    purchasing and distributing cocaine, Robinson helped the conspiracy in other ways, Valentin
    explained. Robinson introduced      Valentin to Troy Allison, who became one of Valentin’s “good
    customer[s]” of cocaine.1 Valentin testified that Robinson once accompanied him to Memphis,
    Tennessee, to pick up “a couple kilos” of cocaine.
    Most of the recorded telephone conversations consist of Robinson’s ordering various
    quantities of cocaine.2 But the calls reveal other aspects of Robinson’s involvement with the
    business: Robinson twice warns Valentin about police investigation into Valentin’s activities;
    Valentin several times asks Robinson to help collect money from individuals whom Valentin had
    given cocaine on credit; and Valentin on one occasion discusses with Robinson how to retrieve a
    safe full of cash from a car impounded by the police.
    After the presentation of all evidence, the district court charged the jury, in part:
    If you determine defendant is guilty of the offense charged in Count 1, you
    must then determine whether that offense involved the particular quantity of drugs
    charged in the indictment. In Count 1 defendant is charged with conspiring to
    distribute 5 kilograms or more of a mixture and substance containing a detectable
    amount of cocaine hydrochloride. On the verdict form I have asked you to answer
    some questions about the amount of the mixture and substance containing a
    detectable amount of cocaine hydrochloride in this offense. In determining the
    amount of controlled substance involved in each of these crimes, you should consider
    all of my previous instructions regarding the consideration of evidence. You should
    only answer yes to one of these questions on the verdict form if you determine, first,
    that defendant is guilty beyond a reasonable doubt of the particular offense charged
    in the indictment, and, second, that the government has proven beyond a reasonable
    doubt that the offense involved the specified quantity of a mixture and substance
    containing a detectable amount of cocaine hydrochloride listed in the question.
    Question 1(A) of the verdict form directed the jury to complete the following sentence: “We, the
    jury, unanimously find that the defendant, ___ (IS NOT/IS) guilty of the offense charged in Count
    1 of the Indictment.” If the jury answered “IS guilty” to Question 1(A), they were directed to
    answer “Yes” or “No” to Question 1(B): “Do you, the jury, unanimously find the Government has
    proved beyond a reasonable doubt that the offense charged in Count 1 of the Indictment involved
    five kilograms or more of a mixture or substance containing cocaine hydrochloride?” If the jury
    answered “No” to Question 1(B), they were asked to answer Question 1(C): whether the jury found
    the quantity of cocaine to be at least 500 grams.
    1
    Troy Allison testified that Robinson had introduced him to Valentin. Allison purchased “a quarter kilo” of
    cocaine from Valentin upon meeting him and continued to buy from him after that. Allison “ultimately buil[t] up to”
    buying one kilogram of cocaine at a time from Valentin, with his largest single purchase being two kilograms.
    2
    In the 14 conversations played for the jury, Valentin and Robinson discuss a minimum total of 38-and-a-half
    ounces of cocaine.
    No. 07-5474               United States v. Robinson                                             Page 3
    During their deliberations, the jury sent a question to the court inquiring “whether Mr.
    Robinson must have knowledge of the selling of 5 kilograms of cocaine hydrochloride or if he has
    to have direct involvement with selling 5 kilograms of cocaine hydrochloride.” Robinson’s counsel
    argued “that knowledge is required” and “that the answer should be yes.” The district court,
    however, responded:
    With respect to the conspiracy, the instructions indicate that the government
    must prove that two or more persons conspired or agreed to commit the crime of
    distributing cocaine hydrochloride, the defendant knowingly joined the conspiracy,
    and the defendant voluntarily and intentionally participated in the conspiracy.
    Again, the essence of the conspiracy is the agreement, not the accomplishment of the
    act.
    Concerning the drug quantities, you are merely to determine what quantity
    was involved in the conspiracy the defendant participated in, in the event you find
    he participated in a conspiracy.
    The jury returned a verdict of guilty and found that the quantity of cocaine involved in the
    conspiracy was five kilograms or more. The district court imposed a sentence of life imprisonment,
    and Robinson timely appealed his conviction to this Court.
    II. ANALYSIS
    A.         Drug Quantity Instruction
    “This court reviews a district court’s ‘actions in responding to questions from the jury’ for
    abuse of discretion.” United States v. Davis, 
    490 F.3d 541
    , 548 (6th Cir. 2007) (quoting United
    States v. August, 
    984 F.2d 705
    , 712 (6th Cir. 1992)). “This circuit has set a high standard for
    reversal of a conviction on the grounds of improper instructions.” United States v. Khalil, 
    279 F.3d 358
    , 367 (6th Cir. 2002) (quoting United States v. Sheffey, 
    57 F.3d 1419
    , 1429 (6th Cir. 1995)). “A
    reviewing court may reverse a judgment only if the instructions, viewed as a whole, were confusing,
    misleading and prejudicial.” 
    Id. (quoting United
    States v. Clark, 
    988 F.2d 1459
    , 1468 (6th Cir.
    1993)).
    In its initial instructions, and again in response to the jury’s question, the district court
    directed the jury to determine the quantity of cocaine “involved in the conspiracy.” These
    instructions tracked the language of 21 U.S.C. § 841(b)(1)(A), which provides:
    In the case of a violation of [21 U.S.C. § 841(a)] involving . . . 5 kilograms or more
    of a mixture or substance containing a detectable amount of . . . cocaine . . . such
    person shall be sentenced to a term of imprisonment which may not be less than 10
    years or more than life . . . If any person commits a violation of this subparagraph
    . . . 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.
    (Emphasis added).3 21 U.S.C. § 841(a)(1) makes it “unlawful for any person knowingly or
    intentionally—to . . . distribute . . . a controlled substance.” 21 U.S.C. § 846 in turn provides: “Any
    person who attempts or conspires to commit any offense defined in this title 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.” The district court thus instructed the jury that the relevant quantity
    3
    Robinson has two prior convictions for felony drug offenses.
    No. 07-5474           United States v. Robinson                                                  Page 4
    determination is of the quantity involved in the violation of 21 U.S.C. §841(a) — in this case, a
    conspiracy to distribute cocaine. The jury’s finding that the quantity equaled or exceeded the
    threshold amount of five kilograms triggered a mandatory life sentence for Robinson.
    Citing our decision in United States v. Pruitt, 
    156 F.3d 638
    (6th Cir. 1998), Robinson argues
    that a drug conspirator is culpable only for quantities personally attributable to him. The issue in
    Pruitt, however, was “whether a conspiracy involving multiple overt acts is nonetheless ‘a violation’
    of [21 U.S.C.] § 841(a)” such that the drug quantities from those multiple acts can be aggregated for
    sentencing under 21 U.S.C. § 841(b)(1)(A). 
    Id. at 644.
    This Court answered the question in the
    affirmative, noting that “a conspiracy is a single, unified offense” and that “the traditional rule
    . . . treats a conspiracy as a whole.” 
    Id. We thus
    interpreted 21 U.S.C. § 841(b)(1)(A) to focus on
    the threshold quantity involved in the entire conspiracy.
    Robinson nonetheless contends that other language from that opinion supports his position.
    He points, for example, to our observation in Pruitt that “[w]hile a person who participates in a drug
    conspiracy does not necessarily agree to a specific amount in advance, no defendant may be held
    responsible for acts beyond the scope of his or her participation in the conspiracy.” 
    Id. at 644-45
    (citing United States v. Myers, 
    102 F.3d 227
    , 237 (6th Cir. 1996) (citing in turn Pinkerton v. United
    States, 
    328 U.S. 640
    , 646-47 (1946))). “[T]his rule,” we explained, “provides adequate protection
    against the possibility that a less culpable, ‘small-time’ seller of drugs will be caught up in the sweep
    of § 841(b) due to the acts of coconspirators.” 
    Id. at 645.
    We also observed that “the district court
    included only amounts for which [the appellant] was directly responsible, rather than imputing to
    him the acts of other defendants, despite conviction on the conspiracy count.” 
    Id. These statements
    do not help Robinson as much as he would like. Again, the issue in Pruitt
    was whether a conspiracy comprising multiple transactions was a single violation of 21 U.S.C.
    § 841(a). The issue was not whether the appellant was culpable for acts of his co-conspirators, and
    any pronouncements on that topic are dicta. Moreover, that portion of Pruitt turned on an analysis
    of Pinkerton. Although our Pinkerton analysis was correct, it is inapplicable here. See United
    States v. Collins, 
    415 F.3d 304
    , 313 (4th Cir. 2005) (“The principles outlined in Pinkerton . . . have
    no applicability to a conviction under § 846. Pinkerton principles are relevant when a conspirator
    is charged with a substantive offense arising from the actions of a co-conspirator, not when a
    conspirator is charged with conspiracy.”). It is true that a conspirator is liable for the substantive
    offenses of his co-conspirators only if those offenses are, among other things, reasonably foreseeable
    to him. 
    Pinkerton, 328 U.S. at 647-48
    . But this principle is distinct from the equally established
    rule that conspiracy is an inchoate offense that needs no substantive offense for its completion.
    Ianelli v. United States, 
    420 U.S. 770
    , 777-78 (1975). The district court here was correct to remind
    the jury that “the essence of the conspiracy is the agreement, not the accomplishment of the act.”
    See United States v. Spearman, 
    186 F.3d 743
    , 746 (6th Cir. 1999) (“An overt act need not be proven
    in a § 846 conspiracy.”) (quoting United States v. Bourjaily, 
    781 F.2d 539
    , 544 (6th Cir. 1986)).
    Our holding in Pruitt affirms this understanding of drug conspiracies. We distinguished
    culpability for the conspiracy itself from culpability for the substantive offenses of co-conspirators.
    Although a “small-time” drug seller may not be responsible for all the transactions or actions of his
    associates, he is responsible for the conspiracy in which he participated. While we observed that
    the district court included only amounts for which it found the appellant directly responsible, we
    noted this fact only inasmuch as it demonstrated that he was not improperly held culpable for the
    substantive offenses of his co-defendants. 
    Pruitt, 156 F.3d at 645
    . And we recognized that 21
    U.S.C. § 841(b)(1)(A) prescribes mandatory sentences for “a violation” — including a conspiracy
    — “involving” certain threshold amounts of drugs. 
    Id. Accordingly, the
    quantity instructions here
    did not improperly lead the jury to convict Robinson for the substantive acts of his co-conspirators.
    No. 07-5474              United States v. Robinson                                                          Page 5
    Similarly unavailing is Robinson’s suggestion that the quantity instructions violated the rule
    articulated by the Supreme Court in Apprendi v. New Jersey, 
    530 U.S. 466
    (2000). Under Apprendi,
    “[o]ther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the
    prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.”
    
    Id. at 490.
    Here, the “fact” that increases the default penalty for a conspiracy to distribute drugs is
    the quantity of drugs involved in the conspiracy.
    The First Circuit has noted that Apprendi did not overrule the Supreme Court’s earlier
    decision that
    as long as (1) the jury finds beyond a reasonable doubt that a defendant participated
    in a conspiracy, and (2) the Court sentences him within the statutory maximum
    applicable to that conspiracy, the court may “determine both the amount and the
    kind of ‘controlled substances’ for which [the] defendant should be held accountable
    — and then . . . impose a sentence that varies depending upon amount and kind.”
    Derman v. United States, 
    298 F.3d 34
    , 42 (1st Cir. 2002) (quoting Edwards v. United States, 
    523 U.S. 511
    , 513-14 (1998)) (emphasis in original). The jury need only determine that the defendant
    participated in a conspiracy involving “a type and quantity of drugs sufficient to justify a sentence
    above the default statutory maximum.” 
    Id. at 43.
    Most other circuits have agreed that Apprendi is
    satisfied where the jury finds, beyond a reasonable doubt,    the quantity of drugs involved in the
    conspiracy as a whole under 21 U.S.C. § 841(b)(1)(A).4 See United States v. Phillips, 
    349 F.3d 138
    ,
    142-43 (3rd Cir. 2003), vacated and remanded on other grounds sub nom. Barbour v. United States,
    
    543 U.S. 1102
    (2005), United States v. Turner, 
    319 F.3d 716
    , 722-23 (5th Cir. 2003), United States
    v. Knight, 
    342 F.3d 697
    , 710 (7th Cir. 2003), United States v. Stiger, 
    413 F.3d 1185
    , 1192-93 (10th
    Cir. 2005), vacated and remanded on other grounds sub nom. Mack v. United States, 
    543 U.S. 1107
    (2005); but see United States v. Collins, 
    415 F.3d 304
    , 313-14 (4th Cir. 2005) and United States v.
    Banuelos, 
    322 F.3d 700
    , 704-05 (9th Cir. 2003).
    Here, the district court had no occasion to determine the amount or kind of drugs for which
    Robinson was personally responsible because there was no range within which the court had
    discretion to choose a sentence; the quantity of cocaine involved in the conspiracy and Robinson’s
    prior felony drug convictions triggered a mandatory life sentence. Therefore, because the jury found
    beyond a reasonable doubt that Robinson had participated in a conspiracy that involved five or more
    kilograms of cocaine, there can be no Apprendi error. See 
    Derman, 298 F.3d at 42-43
    .
    Viewed under the abuse-of-discretion standard, the district court’s response to the jury’s
    question was not “confusing, misleading and prejudicial.” 
    Khalil, 279 F.3d at 367
    . Given that the
    court’s instruction was faithful to the language of 21 U.S.C. § 841(b)(1)(A), Robinson’s argument
    that a different answer was required does not overcome our “high standard for reversal of a
    conviction on the grounds of improper instructions.” 
    Id. B. Lesser-Included-Offense
    Instruction
    Robinson argues that the district court should have charged a violation of 21 U.S.C.
    §841(b)(1)(C) (distribution of cocaine with no finding of a threshold quantity) as a lesser-included
    offense. By failing to do so, Robinson insists, the court deprived the jury of a “third option” and
    presented them with an “all-or-nothing choice.”
    4
    We have previously adopted this view in unpublished opinions. See United States v. Alanis, 75 F. App’x 344,
    351-52 (6th Cir. 2003); United States v. Grooms, 194 F. App’x 355, 362 (6th Cir. 2006).
    No. 07-5474                United States v. Robinson                                                          Page 6
    Robinson concedes that he did not request such a charge and that review on this issue is for
    plain error. See United States v. Jones, 
    403 F.3d 817
    , 821 (6th Cir. 2005) (“[W]here a ‘defendant
    neither requested nor submitted a lesser-included-offense instruction, and did not object to the
    instructions given by the trial judge, the jury instructions are reviewable only for plain error.’”)
    (quoting United States v. Donathan, 
    65 F.3d 537
    , 540 (6th Cir. 1995)). “Under the plain error
    standard, we may reverse if (1) there was error that (2) was plain, (3) affected a substantial right, and
    (4) ‘seriously affects the fairness, integrity, or public reputation of judicial proceedings.’” United
    States v. Martin, 
    520 F.3d 656
    , 658 (6th Cir. 2008) (quoting United States v. Oliver, 
    397 F.3d 369
    ,
    378 (6th Cir. 2005) (citing United States v. Olano, 
    507 U.S. 725
    , 732 (1993))).
    A criminal defendant is entitled to an instruction on a lesser-included-offense
    if: (1) a proper request is made; (2) the elements of the lesser offense are identical
    to part of the elements of the greater offense; (3) the evidence would support a
    conviction on the lesser offense; and (4) the proof on the element or elements
    differentiating the two crimes is sufficiently disputed so that a jury could consistently
    acquit on the greater offense and convict on the lesser.
    United States v. Colon, 
    268 F.3d 367
    , 373 (6th Cir. 2001) (quoting United States v. Monger, 
    185 F.3d 574
    , 576 (6th Cir. 1999)).
    Because Robinson never requested a lesser-included-offense instruction, he did not satisfy
    the first prong of Colon and cannot prove any error, much less plain error. Moreover, Robinson’s
    rights were not prejudiced; the verdict form required the jury to determine beyond a reasonable
    doubt whether the threshold amounts of five kilograms or 500 grams were involved in the
    conspiracy. An answer of “No” to both of the quantity interrogatories necessarily would have meant
    that the jury did not find either of the threshold amounts. The verdict form thus provided a “third
    option” by allowing the jury to convict Robinson of a conspiracy that did not involve any particular
    quantity of cocaine.
    C.         Sufficiency of the Evidence
    Robinson argues that the evidence was insufficient to prove the existence of a conspiracy.5
    “In determining the sufficiency of the evidence to support a guilty verdict ‘the relevant question is
    whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier
    of fact could have found the essential elements of the crime beyond a reasonable doubt.’” 
    Martin, 520 F.3d at 660
    (quoting United States v. Pearce, 
    912 F.2d 159
    , 161 (6th Cir. 1990) (quoting in turn
    Jackson v. Virginia, 
    443 U.S. 307
    , 319 (1979))).
    To establish a violation of 21 U.S.C. § 846, “the government must prove, beyond a
    reasonable doubt, ‘(1) an agreement to violate drug laws, (2) knowledge and intent to join the
    conspiracy, and (3) participation in the conspiracy.’” United States v. Caver, 
    470 F.3d 220
    , 232 (6th
    Cir. 2006) (quoting United States v. Gibbs, 
    182 F.3d 408
    , 420 (6th Cir. 1999)). Drug conspiracies
    “often assume[] a vertical pattern of distribution, where each successive distributor sells a lower
    volume to any particular customer. . . . [A]n agreement to supply drugs to a given area can be
    inferred from the interdependence of the enterprise.” 
    Id. at 233.
    “In a drug distribution ‘chain’
    conspiracy, it is enough to show that each member of the conspiracy realized that he was
    participating in a joint venture, even if he did not know the identities of every other member, or was
    not involved in all the activities in furtherance of the conspiracy.” United States v. Martinez, 
    430 F.3d 317
    , 332-33 (6th Cir. 2005). “‘[E]vidence of repeat purchases provides evidence of more than
    a mere buyer-seller relationship,’ and the quantity of drugs may also support an inference of
    5
    Robinson does not challenge the sufficiency of the evidence regarding the threshold quantity of cocaine.
    No. 07-5474               United States v. Robinson                                                               Page 7
    conspiracy.” 
    Id. at 333
    (quoting United States v. Brown, 
    332 F.3d 363
    , 373 (6th Cir. 2003)). Also,
    the “trust involved” in delivering drug quantities on credit “suggests more than a buyer-seller
    relationship.” United States v. Nesbitt, 
    90 F.3d 164
    , 167 (6th Cir. 1996).
    The evidence was sufficient to show that Robinson conspired with Juan Valentin and others
    to distribute cocaine. Valentin testified that he and Robinson shared a “business relationship” and
    that they worked together to sell cocaine. Robinson purchased drugs from Valentin once or twice
    a week, sometimes on credit, over a period of several years. On at least one occasion, Robinson
    accompanied Valentin to a source city to pick up “a couple kilos” of cocaine. Robinson helped
    collect money other buyers owed Valentin. He warned Valentin about police activity. He conferred
    with Valentin about how to recover drug proceeds from an impounded car. Robinson introduced
    Troy Allison to Valentin, and Allison became one of Valentin’s “good customer[s].” From this
    evidence a rational trier of fact could find that there was an agreement to violate drug laws, that
    Robinson knowingly and intentionally joined the conspiracy, and that Robinson participated in the
    conspiracy.
    D.       Variance
    Robinson argues that there was a prejudicial variance between the indictment and the proof
    at trial because the indictment alleged one large conspiracy while the evidence demonstrated several
    smaller conspiracies.   “The court of appeals reviews the question of whether a variance has occurred
    de novo.”6 
    Caver, 470 F.3d at 235
    . “Within the context of a conspiracy, a variance constitutes
    reversible error only if a defendant demonstrates that he was prejudiced by the variance and that the
    ‘indictment allege[d] one conspiracy, but the evidence can reasonably be construed only as
    supporting a finding of multiple conspiracies.’” 
    Id. at 235-36
    (quoting United States v. Warner, 
    690 F.2d 545
    , 548 (6th Cir. 1982)) (emphasis in original). “In making this determination, the evidence
    must be viewed in the light most favorable to the government.” 
    Id. 1. Existence
    of a Single Conspiracy
    “To prove a single conspiracy, the government need only show that each alleged conspirator
    had knowledge of and agreed to participate in what he knew to be a collective venture directed
    toward a common goal.” United States v. Smith, 
    320 F.3d 647
    , 653 (6th Cir. 2002), vacated and
    remanded on other grounds, 
    510 U.S. 1180
    (2005). “[A] single conspiracy does not become
    multiple conspiracies simply because each member of the conspiracy did not know every other
    member, or because each member did not know of or become involved in all of the activities in
    furtherance of the conspiracy.” 
    Warner, 690 F.2d at 549
    . Drug conspiracies “are often ‘chain’
    conspiracies” which “normally involve numerous sales and resales of drugs until they reach the
    ultimate consumers.” 
    Id. “Because the
    success of participants on each level of distribution is
    dependent upon the existence of other levels of distribution, each member of the conspiracy must
    realize that he is participating in a joint enterprise, even if he does not know the identities of many
    of the participants.” 
    Id. Here, the
    government proved that Robinson knew about and agreed to participate in a
    collective venture to sell cocaine in eastern Tennessee. The same evidence supporting a finding of
    Robinson’s participation in the conspiracy supports a finding that there was a single conspiracy.
    Robinson cooperated with both Valentin and “downstream” sellers to maintain a profitable
    enterprise. Robinson helped Valentin acquire drugs, develop new customers, avoid police detection,
    6
    If the issue of variance is not raised at trial, however, review is for plain error. 
    Caver, 470 F.3d at 235
    . The
    parties have not indicated whether Robinson raised this issue at trial or, if he did, where in the record it appears. We
    find that, under either standard of review, Robinson has not shown that a variance occurred or that his rights were
    prejudiced.
    No. 07-5474           United States v. Robinson                                                 Page 8
    and collect money. These actions support the inference that Robinson wanted to protect Valentin’s
    interests, at least so he could maintain him as a source. Also, Robinson made sure that he had
    enough cocaine to supply the dealers who were buying from him. The evidence points to a
    conclusion that there was an “interdependence of the enterprise,” 
    Caver, 470 F.3d at 233
    , and we
    cannot say that the evidence “can reasonably be construed only as supporting a finding of multiple
    conspiracies.” 
    Id. at 236
    (quoting 
    Warner, 690 F.2d at 548
    ) (emphasis in original).
    2.      Prejudice
    “[E]ven if a variance exists, it does not constitute reversible error ‘unless it prejudices [the
    defendant’s] substantial rights.’” United States v. Lee, 
    991 F.2d 343
    , 349 (6th Cir. 1993) (quoting
    United States v. Guerra-Marez, 
    928 F.2d 665
    , 671 (5th Cir. 1991)). “Moreover, ‘if the government
    proves multiple conspiracies and a defendant’s involvement in at least one of them, then clearly
    there is no variance affecting that defendant’s substantial rights.’” 
    Id. Even assuming
    a variance, Robinson has failed to demonstrate how he has been prejudiced.
    This is not a case where there could be a danger of “transferred guilt” from evidence of multiple
    conspiracies in which Robinson was not involved. In any event, even if the evidence proved only
    multiple conspiracies, the government has proved Robinson’s involvement in at least one of them.
    CONCLUSION
    For the foregoing reasons, we AFFIRM Robinson’s conviction and sentence.
