    Before: MOORE, CLAY, and STRANCH, Circuit Judges.
    KAREN NELSON MOORE, Circuit Judge. In 2017, a Kentucky jury found Patrick
    Baker guilty of reckless homicide, robbery in the first degree, impersonating a peace officer, and
    tampering with physical evidence in connection with the death of Donald Mills. Baker was
    sentenced to nineteen years’ imprisonment in state custody. Two years later, Baker received a
    pardon for offenses stemming from his conduct related to Mills’s death from then-Governor of
    Kentucky Matthew Bevin. In 2021, however, Baker was federally indicted on one count of
    unlawfully causing Mills’s death through the use of a firearm during and in relation to a drug
    trafficking offense, based on the same conduct for which he had been pardoned.            A jury
    subsequently found Baker guilty, and the district court sentenced him to a total of 474 months’
    imprisonment in federal custody. On appeal, Baker argues that (1) his due-process rights were
    violated because the federal government vindictively prosecuted him after he received a
    gubernatorial pardon for state-law offenses based on the same underlying conduct; (2) the evidence
    No. 22-5067, United States v. Baker
    presented at trial was insufficient to sustain a conviction; and (3) he is entitled to discovery and an
    evidentiary hearing on his claims that a government witness testified falsely against him and that
    the government relatedly violated its Brady obligations regarding impeachment material about the
    same witness. For the reasons that follow, we AFFIRM.
    I. BACKGROUND
    At around 5:00 AM on May 9, 2014, two men kicked in the door of Donald Mills’s home,
    where Mills and his family were sleeping. R. 140 (Trial Tr. at 97) (Page ID #737). The men
    claimed to be federal law-enforcement officers. Id. at 98 (Page ID #738). One of the men took
    Mills’s wife, Charlene James Mills, and children into a separate bedroom while the other man
    remained with Mills. Id. at 98–99 (Page ID #738–39). According to Charlene, the man who stayed
    with her husband was taller and “a lot skinnier” than the man who was with her and the children.
    Id. at 101 (Page ID #741). She testified that the taller, skinnier man asked Mills: “Where is the
    dope, and where is the money?” Id. at 99 (Page ID #739). While separated from her husband,
    Charlene heard five or six gunshots from the other side of the house. Id. at 102 (Page ID #742).
    She testified that she did not hear a struggle or fight prior to the gunshots. Id. at 108 (Page ID
    #748).
    As the two men left Mills’s house, Charlene retrieved a gun and went out to the porch to
    fire at the men’s vehicle as it pulled away. Id. She described the vehicle as a maroon Ford F-150
    and said that she had seen the truck parked in her driveway two days prior. Id. She did not know
    who drove the truck two days earlier, but stated that Elijah Messer had exited from the passenger’s
    side of the truck. Id. at 108–09 (Page ID #748–49). After the truck drove away, Charlene went to
    the master bedroom, where she found her husband “laying up against the wall with towels held up
    2
    No. 22-5067, United States v. Baker
    to his chest bleeding to death.” Id. at 109 (Page ID #749). Mills told her that he did not know
    who shot him. Id. Mills died after being transported to a hospital. Id. at 118 (Page ID #758).
    At the time of his death, Mills sold oxycodone and would typically keep 600 to 1,000
    oxycodone pills in his house at any given time. Id. at 106–07 (Page ID #746–47). According to
    his wife, however, Mills did not have any oxycodone pills in their house during the early hours of
    May 9, although he did have some Neurontin and Zanaflex. Id. at 118–19 (Page ID #758–59).
    Charlene James Mills testified that it was not a secret in their community that Mills sold
    oxycodone. Id. at 107 (Page ID #747).
    Nathan Wagoner testified that in April and May 2014, Wagoner and Baker sold oxycodone
    to each other, and that Baker was $1,200 in debt to Wagoner as a result of Baker’s addiction to
    oxycodone. Id. at 195–96 (Page ID #835–36). Wagoner was friendly with Mills and had obtained
    oxycodone from Mills since around 2007. Id. at 197 (Page ID #837). One or two weeks before
    Mills was killed, Baker went to Wagoner’s apartment and mentioned that he wanted to rob
    “someone with pills and money,” but did not specify whom he intended to rob. Id. at 198–99
    (Page ID #838–39). Wagoner later talked to Stephanie Smith, who tried to convince him to help
    Baker rob Mills and told Wagoner that she and Baker “had been staking out Donald Mills’ place.”
    Id. at 205 (Page ID #845). Smith and Baker had staked Mills’s house out “[f]rom an elevated
    position with binoculars, . . . for, like, two days watching his every move.” Id. At the time,
    however, Wagoner did not know Smith was talking about Mills. Id. at 205 (Page ID #845). On
    the evening of May 8, Wagoner returned to Smith’s trailer. Id. at 206 (Page ID #846). Baker,
    Christopher Wagner, Steven Hensley, and Wagoner’s younger brother, Austin, were all at Smith’s
    3
    No. 22-5067, United States v. Baker
    trailer. Id. Shortly after Wagoner arrived, Wagner and Baker left in a maroon Ford F-150, which
    Wagoner identified as belonging to Baker. Id. at 209, 215–16 (Page ID #849, 855–56).
    Wagner testified that, on May 8, Baker gave him a firearm to use for the robbery. Id. at
    261 (Page ID #901). Baker told Wagner that Mills supposedly had 1,500 Roxicet 30s1 and
    $200,000 in cash in Mills’s home. Id. at 257 (Page ID #897). They then went to Smith’s trailer
    but left in the maroon F-150 shortly after Wagoner arrived. Id. at 267–68 (Page ID #907–08).
    Baker and Wagner drove to Adam Messer’s trailer, where they met Elijah Messer. Id. at 270 (Page
    ID #910). The three men smoked meth and discussed the robbery. Id. at 273–74 (Page ID #913–
    14). Wagner testified that it was his impression that Elijah “was the ring leader,” and that Elijah
    wanted Wagner and Baker to conduct the robbery on his behalf because Elijah would be
    recognized easily as a result of having only one leg. Id. at 274–75 (Page ID #914–15). Baker then
    showed Wagner and Elijah Messer an aerial photograph of Mills’s house on Baker’s iPad. Id. at
    276–77 (Page ID #916–17). Wagner testified that the plan was for him, Baker, and Elijah Messer
    to split the pills and cash among them after the robbery. Id. at 279 (Page ID #919).
    Wagner and Baker then left in Baker’s truck, and Elijah Messer followed them in his
    brother’s truck, which was driven by Angela Mills,2 who had been at Adam Messer’s trailer while
    the three men discussed the robbery. Id. at 280–81, 284–85 (Page ID #920–21, 924–25). After
    arriving at Donald Mills’s house, Baker busted through the front door. Id. at 287 (Page ID #927).
    Wagner corroborated the version of events given by Charlene James Mills and testified that he
    1
    A “Roxicet 30” is an oxycodone pill. R. 141 (Trial Tr. at 10) (Page ID #981).
    2
    Angela Mills was also known to some of the witnesses as Michelle Brown or Michelle Brown Mills. R. 141
    (Trial Tr. at 208–09) (Page ID #1179–80); R. 144 (Trial Tr. at 102) (Page ID #1939). There is no indication that she
    is related to Donald Mills.
    4
    No. 22-5067, United States v. Baker
    stayed with Mills’s wife and children, while Baker tried to find out from Mills where the pills and
    money were. Id. at 291–93 (Page ID #931–33). Wagner heard several gunshots, walked toward
    the front door, and saw Baker come out of a room. Id. at 295 (Page ID #935). The two men left
    in Baker’s truck, and Baker told Wagner that Mills “pulled a gun” and that “I had to shoot him.”
    Id. at 298 (Page ID #938). Baker took approximately five oxycodone pills from Mills’s house. R.
    141 (Trial Tr. at 14) (Page ID #985).
    Hensley also testified that Baker said he was planning to rob “a guy that had a bunch of
    money and some pills in a safe.” Id. at 163 (Page ID #1134). Baker was in his truck with Wagner
    during this conversation with Hensley. Id. Baker’s ex-wife testified that Baker told her that he
    had planned to rob Mills but that “Mills pulled a gun on him and [Baker] had to shoot [Mills] in
    self-defense.” Id. at 178 (Page ID #1149). Elijah Messer testified that Baker and Wagner arrived
    at Adam Messer’s trailer in the early hours of May 9. Id. at 210–12 (Page ID #1181–83). Elijah
    Messer corroborated that Baker showed him and Wagner an aerial shot of Mills’s house and that
    the three of them discussed robbing Mills. Id. at 214–16 (Page ID #1185–87). Elijah Messer
    testified that the plan was that “[Baker] was going to give me some [pills]. And then I was going
    to buy some [pills], or trade some meth for some [pills].” Id. at 218 (Page ID #1189). Wagner
    and Baker would split the rest of the pills. Id. After the robbery, Baker told Elijah Messer that he
    shot Mills because Mills had a gun and tried to shoot him. Id. at 224–25 (Page ID #1195–96).
    Adam Messer also testified that sometime at night on May 8 or early in the morning of
    May 9, he heard his brother, Baker, and Wagner discussing “Mills flashing money” and having
    “all of these pills.” R. 144 (Trial Tr. at 112) (Page ID #1948). Adam Messer testified that his
    brother was a drug dealer and would get 100 to 200 oxycodone pills from Mills at a time, which
    5
    No. 22-5067, United States v. Baker
    Elijah would sell “to support his habit.” Id. at 113 (Page ID #1949). Adam Messer also saw the
    aerial photograph of Mills’s house on Baker’s iPad. Id. at 116–17 (Page ID #1952–53).
    In July 2014, Baker was indicted in the Knox County Circuit Court on several state-law
    counts related to Mills’s death. R. 149 (Mot. Dismiss/Limit Sentence at 1) (Page ID #2774). In
    November 2017, a Kentucky jury found Baker guilty of reckless homicide; robbery in the first
    degree; impersonating a peace officer; and tampering with physical evidence, and he was
    sentenced to a total of nineteen years’ imprisonment. Id. Two years later, he received a pardon
    from then-Governor of Kentucky Matthew Bevin, who commuted his sentence to time served. R.
    165 (Presentence Investigation Report (“PSR”) ¶ 116) (Page ID #3005). Governor Bevin stated
    in the pardon that “the evidence supporting [Baker’s] conviction is sketchy at best,” and expressed
    that he was “not convinced that justice has been served in the death of Donald Mills,” nor was he
    “convinced that the evidence has proven the involvement of Patrick Baker as murderer.” Id.
    In May 2021, a federal grand jury indicted Baker on one count of unlawfully causing
    Mills’s death through the use of a firearm during and in relation to a drug trafficking offense,
    namely conspiracy to distribute oxycodone, in violation of 
    18 U.S.C. § 924
    (j)(1) and 
    21 U.S.C. § 846
    . R. 1 (Indictment) (Page ID #1). Following a nine-day trial, the jury found Baker guilty on
    that count. R. 120 (Verdict) (Page ID #548). Baker then moved to dismiss the indictment against
    him, or in the alternative, to limit his federal sentence to no more than nineteen years’
    imprisonment, the same length as his state-court sentence prior to the pardon and commutation.
    R. 149 (Mot. Dismiss/Limit Sentence at 1) (Page ID #2774). He also filed a Brady motion, seeking
    the production of impeachment material related to any deals for leniency or sentence modification
    struck with government witnesses Wagoner, Wagner, and Elijah Messer. R. 151 (Brady Mot. at
    6
    No. 22-5067, United States v. Baker
    1) (Page ID #2781). The district court denied both motions. R. 159 (Mem. Op. & Order at 1)
    (Page ID #2933). The district court sentenced Baker to a term of 504 months’ imprisonment, with
    a downward departure of 30 months to account for the time that Baker had already served in state
    custody, for a total of 474 months’ imprisonment. R. 168 (Sent’g Hr’g Tr. at 93–94) (Page ID
    #3143–44). Baker now timely appeals. R. 163 (Notice of Appeal) (Page ID #2967).
    II. VINDICTIVE PROSECUTION
    Baker argues that the federal government vindictively prosecuted him by pursuing federal-
    law charges against him only after he received a gubernatorial pardon for his state-law conviction
    based on the same underlying conduct. We have held that “the ultimate decision whether to
    dismiss an indictment for prosecutorial vindictiveness is reversible only if the district court abused
    its discretion.” United States v. LaDeau, 
    734 F.3d 561
    , 565 (6th Cir. 2013). As we have explained:
    Because a district court has no discretion not to abide by governing law, an
    erroneous legal conclusion deserves no deference on appeal. As a result, even
    under abuse-of-discretion review, a district court commits error requiring reversal
    if its determination whether to dismiss an indictment for prosecutorial
    vindictiveness depends upon a misapplication of pertinent law. By contrast, where
    the district court’s dismissal determination hinges upon factual findings, we defer
    to the district court’s decision unless the findings upon which it was predicated are
    clearly erroneous.
    
    Id. at 566
     (internal citations omitted).
    The Due Process Clause “prohibits the prosecution from punishing a defendant for
    exercising a protected statutory or constitutional right.” 
    Id.
     A defendant can demonstrate
    vindictive prosecution either through actual vindictiveness or by showing a “realistic likelihood of
    vindictiveness.” Bragan v. Poindexter, 
    249 F.3d 476
    , 481 (6th Cir. 2001) (quoting United States
    v. Andrews, 
    633 F.2d 449
    , 453 (6th Cir. 1980)).            To establish a “realistic likelihood of
    vindictiveness,” a defendant must show “that (1) the prosecutor has ‘some “stake”’ in deterring
    7
    No. 22-5067, United States v. Baker
    the [defendant’s] exercise of his rights and (2) the prosecutor’s conduct was somehow
    ‘unreasonable.’” 
    Id. at 482
     (quoting United States v. Anderson, 
    923 F.2d 450
    , 453–54 (6th Cir.
    1991)). “Once a court has found that a realistic likelihood of vindictiveness exists, the government
    bears the burden of disproving it or justifying the challenged state action.” 
    Id.
     But “[i]f the
    government fails to present evidence sufficient to rebut the presumption, the presumption stands
    and the court must find that the prosecutor acted vindictively.” 
    Id.
    Baker therefore must demonstrate that federal prosecutors had some stake in deterring the
    exercise of his state-law right to seek a pardon, but his argument falters as a result of the separate-
    sovereigns (or dual-sovereignty) doctrine. Under the separate-sovereigns doctrine, the Fifth
    Amendment right against double jeopardy is not violated when a defendant is indicted and
    convicted in federal court after already having been convicted of an offense based on the same
    conduct in state court, or vice versa. Abbate v. United States, 
    359 U.S. 187
    , 195 (1959); see also
    Gamble v. United States, 
    139 S. Ct. 1960
    , 1964 (2019). Baker’s claim is further complicated by
    the fact that federal prosecutors generally are afforded broad discretion in decisions involving
    charging. See, e.g., Bordenkircher v. Hayes, 
    434 U.S. 357
    , 364 (1978) (“In our system, so long as
    the prosecutor has probable cause to believe that the accused committed an offense defined by
    statute, the decision whether or not to prosecute, and what charge to file or bring before a grand
    jury, generally rests entirely in his discretion.”).
    Accordingly, we have previously held that a defendant’s due-process rights are not violated
    when state authorities refer the defendant’s case to federal authorities for prosecution, “as long as
    [federal] prosecutors are not acting as rubber stamps and exert their own discretion as to whether
    or not to prosecute.” United States v. Allen, 
    954 F.2d 1160
    , 1166 (6th Cir. 1992). Similarly, we
    8
    No. 22-5067, United States v. Baker
    have also found no due-process violation where state authorities allegedly “triggered” the
    defendant’s federal prosecution by placing a call to federal law enforcement regarding the
    defendant’s guilty plea in state court. United States v. Odom, 
    42 F.3d 1389
    , 
    1994 WL 669675
    , at
    *2 & n.1 (6th Cir. Nov. 29, 1994) (table). Baker has not presented any facts that suggest that
    federal prosecutors simply acted as rubber stamps for the state instead of exercising their own
    discretion in charging him. Baker points to the fact that the U.S. Attorney for the Western District
    of Kentucky announced that his office would consider federally prosecuting individuals pardoned
    by Governor Bevin. Appellant Br. at 30–31. But Baker was prosecuted by the U.S. Attorney for
    the Eastern District of Kentucky. And even so, the fact that federal prosecutors might “consider”
    prosecution of such individuals does not suggest an abdication of federal discretion.
    Our sibling circuits have likewise declined to find prosecutorial vindictiveness in cases
    involving separate sovereigns. See, e.g., United States v. Ng, 
    699 F.2d 63
    , 68 (2d Cir. 1983)
    (“[T]he fact that the prosecutions of the defendants are by two different sovereigns, each acting
    independently under its own laws and in its own interest without any control of or by the other,
    renders inapplicable the concept of prosecutorial vindictiveness.”); United States v. Schoolcraft,
    
    879 F.2d 64
    , 68 (3d Cir. 1989) (per curiam) (“[T]he involvement of a separate sovereign tends to
    negate a vindictive prosecution claim.”); United States v. Johnson, 
    91 F.3d 695
    , 698–99 (5th Cir.
    1996) (concluding that there was no prosecutorial vindictiveness when the defendant was
    prosecuted federally following his acquittal in state court on a capital-murder charge and his
    successful filing of a grievance against two local assistant district attorneys for withholding
    exculpatory evidence); United States v. Heidecke, 
    900 F.2d 1155
    , 1159 (7th Cir. 1990) (concluding
    that there was no prosecutorial vindictiveness when federal prosecutors indicted the defendant
    9
    No. 22-5067, United States v. Baker
    after his state-court indictment was dismissed, in part because “[w]here there are successive
    prosecutions by two sovereigns, as in this case, it is improbable that a realistic likelihood of
    vindictiveness exists”); United States v. Beede, 
    974 F.2d 948
    , 952 (8th Cir. 1992) (concluding that
    “state and federal prosecutors must remain free to exercise their prosecutorial discretion with
    respect to the charging decision” regardless of the other sovereign’s charging decision); United
    States v. Turpin, 
    920 F.2d 1377
    , 1388 (8th Cir. 1990) (holding that the defendant’s due-process
    rights were not violated when his state-court case was dismissed and he was indicted in federal
    court based on the same conduct, even though he was subject to a harsher sentence in federal
    court); United States v. Robison, 
    644 F.2d 1270
    , 1273 (9th Cir. 1981) (holding that “the
    involvement of separate sovereigns tends to negate a vindictive prosecution claim,” but declining
    to hold that “a second prosecution can never be vindictive when it follows a successful defense in
    a foreign jurisdiction”).
    As the Seventh Circuit concluded, “the possibility of institutional bias against retrial and a
    personal prosecutorial stake in the proceedings is minimized” when separate sovereigns initiate
    the two indictments. Heidecke, 
    900 F.2d at 1160
    . And the First Circuit has even suggested that
    “a finding of complicity between federal and state prosecutors” would be required to show
    vindictive prosecution where separate sovereigns are involved. United States v. Stokes, 
    124 F.3d 39
    , 45 n.4 (1st Cir. 1997). Baker has not made any showing of complicity between state and
    federal prosecutors that would make us depart from the holdings of our sibling circuits.
    Baker’s argument also falters on the unreasonableness prong, because new evidence was
    developed between his conviction in state court and his prosecution in federal court. Wagoner
    first talked with law enforcement in August 2021 about his version of the events at issue, and thus
    10
    No. 22-5067, United States v. Baker
    his testimony was newly available at Baker’s federal trial. R. 140 (Trial Tr. at 218) (Page ID
    #858). Wagner also provided additional, previously unavailable, details as part of his testimony
    at Baker’s federal trial. R. 141 (Trial Tr. at 23–27) (Page ID #994–98). The new availability of
    this additional evidence thus provides a possible explanation, unrelated to Baker’s pardon, for the
    federal prosecutors’ decision to seek an indictment against Baker in 2021.
    Although we are troubled by the timing of Baker’s federal prosecution following his state-
    law pardon, and by the impression that Baker may not have received such a lengthy federal
    sentence but for his acceptance of a state-law pardon, we cannot say that the district court abused
    its discretion in finding that there was no reasonable likelihood of vindictiveness in these particular
    circumstances. Cases may arise in which the facts demonstrate that the federal government had a
    stake in defeating a defendant’s exercise of their state-law rights, and thus under such
    circumstances, a defendant’s due-process rights may be violated by a subsequent prosecution by a
    separate sovereign. In this case, however, Baker has not made such a showing.
    III. SUFFICIENCY OF THE EVIDENCE
    A. Standard of Review
    Baker next argues that that the government’s evidence was insufficient to prove beyond a
    reasonable doubt that he unlawfully caused Mills’s death through the use of a firearm during the
    commission of a drug trafficking conspiracy. We review de novo challenges to the sufficiency of
    evidence. United States v. Ray, 
    803 F.3d 244
    , 262 (6th Cir. 2015). If, however, “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,” we must uphold the jury’s
    verdict. Jackson v. Virginia, 
    443 U.S. 307
    , 319 (1979).
    11
    No. 22-5067, United States v. Baker
    In analyzing sufficiency of the evidence issues, “we do not weigh the evidence, consider
    the credibility of witnesses or substitute our judgment for that of the jury.’” United States v.
    Hilliard, 
    11 F.3d 618
    , 620 (6th Cir. 1993). A conviction can be sustained on circumstantial
    evidence alone, “and such evidence need not ‘remove every reasonable hypothesis except that of
    guilt.’” United States v. Ellzey, 
    874 F.2d 324
    , 328 (6th Cir. 1989) (quoting United States v. Stone,
    
    748 F.2d 361
    , 363 (6th Cir. 1984)). Likewise, “the uncorroborated testimony of an accomplice
    may support a conviction under federal law.” United States v. Gallo, 
    763 F.2d 1504
    , 1518 (6th
    Cir. 1985). Baker has not surmounted the heavy burden to show that the evidence was insufficient
    to support his conviction.
    B. Conspiracy to Distribute Oxycodone
    To obtain a conviction against Baker, the prosecution was required to prove that Baker
    caused Mills’s death through use of a firearm “in the course of a violation of subsection (c).” 
    18 U.S.C. § 924
    (j). In relevant part, subsection (c) criminalizes using or carrying a firearm “during
    and in relation to any . . . drug trafficking crime.” 
    Id.
     § 924(c)(1)(A). Subsection (c) further
    defines “drug trafficking crime” as “any felony punishable under the Controlled Substances Act
    (21 U.S.C. 801 et seq.), the Controlled Substances Import and Export Act (21 U.S.C. 951 et seq.),
    or chapter 705 of title 46.” Id. § 924(c)(2). The relevant drug-trafficking crime that formed an
    element of the charged offense was conspiracy to distribute oxycodone, in violation of 
    21 U.S.C. § 846
    . R. 1 (Indictment) (Page ID #1).
    “To obtain a conspiracy conviction under 
    21 U.S.C. § 846
    , ‘the government must prove
    the existence of an agreement to violate the drug laws and that each conspirator knew of, intended
    to join and participated in the conspiracy.’” United States v. Anderson, 
    89 F.3d 1306
    , 1310 (6th
    12
    No. 22-5067, United States v. Baker
    Cir. 1996) (quoting United States v. Pearce, 
    912 F.2d 159
    , 161 (6th Cir. 1990)). Although there
    need not be a “formal, written agreement,” the government must prove “an agreement beyond a
    reasonable doubt.” 
    Id.
     We have previously held that a buyer-seller relationship alone is generally
    insufficient to bring a buyer into the conspiracy, because “mere sales do not prove the existence
    of the agreement that must exist for there to be a conspiracy.” 
    Id.
     If, however, “there is additional
    evidence beyond the mere purchase or sale, from which knowledge of the conspiracy may be
    inferred,” we will uphold a conspiracy conviction. United States v. Grunsfeld, 
    558 F.2d 1231
    ,
    1235 (6th Cir. 1977). Circumstantial evidence that can establish a conspiracy “includes advance
    planning, ongoing purchases or arrangements, large quantities of drugs, standardized transactions,
    an established method of payment, and trust between the buyer and seller.” United States v.
    Williams, 
    998 F.3d 716
    , 728 (6th Cir. 2021).
    Here, the government established evidence of a conspiracy beyond a mere buyer-seller
    relationship. Baker believed that Mills had 1,500 oxycodone pills and $200,000 in cash in his
    home. R. 140 (Trial Tr. at 257) (Page ID #897). Both Wagner and Elijah Messer testified that the
    plan after the robbery was for the three men to split the oxycodone pills among them. 
    Id. at 279
    (Page ID #919); R. 141 (Trial Tr. at 218) (Page ID #1189). Even split among three people, the
    large quantity of oxycodone pills that Baker believed they would recover from the robbery
    suggests the existence of a conspiracy beyond a mere buyer-seller relationship or the acquisition
    of drugs for personal use. Testimony from Wagoner, Wagner, Hensley, Elijah Messer, and Adam
    Messer demonstrated the substantial amount of advance planning that went into the robbery for
    the purpose of obtaining and subsequently distributing the oxycodone. R. 140 (Trial Tr. at 198–
    205, 270) (Page ID #838–45, 910); R. 141 (Trial Tr. at 163, 210–18) (Page ID #1134, 1181–89);
    13
    No. 22-5067, United States v. Baker
    R. 144 (Trial Tr. at 112–17) (Page ID #1948–53). And Adam Messer’s testimony established that
    the robbery and subsequent plan to split the oxycodone pills among Baker, Wagner, and Elijah
    Messer went far beyond Elijah Messer’s regular buyer-seller relationship with Mills, where Elijah
    would purchase 100 to 200 oxycodone pills from Mills at a time, which Elijah would then sell to
    others. R. 144 (Trial Tr. at 113) (Page ID #1949). In sum, there was sufficient evidence from
    which a rational factfinder could conclude that Baker, Wagner, and Elijah Messer conspired to rob
    Mills of a large quantity of oxycodone for the purpose of distributing the oxycodone.
    C. Malice Aforethought
    Baker next argues that the government did not present sufficient proof of malice
    aforethought at trial to sustain his conviction. To obtain a conviction under 
    18 U.S.C. § 924
    (j)(1),
    the government must prove beyond a reasonable doubt that the defendant committed murder, as
    defined by 
    18 U.S.C. § 1111
    . Section 1111 defines murder as “the unlawful killing of a human
    being with malice aforethought.” 
    18 U.S.C. § 1111
    (a). “Malice aforethought may be inferred
    when the defendant ‘grossly deviates from the standard of care to such an extent that a jury could
    conclude that he must have been aware of a serious risk of death or serious bodily injury.’” United
    States v. Conatser, 
    514 F.3d 508
    , 523 (6th Cir. 2008) (quoting United States v. Sheffey, 
    57 F.3d 1419
    , 1430 (6th Cir. 1995)).
    Baker argues that, because his ex-wife, Elijah Messer, and Wagner all testified that Baker
    told them that he killed Mills after Mills pulled out a gun, there was insufficient evidence that
    Baker acted with malice aforethought in killing Mills. R. 140 (Trial Tr. at 298) (Page ID #938);
    R. 141 (Trial Tr. at 178, 224–25) (Page ID #1149, 1195–96). The jury, however, reasonably could
    have chosen to credit the testimony of Mills’s wife that she did not hear a struggle or fight prior to
    14
    No. 22-5067, United States v. Baker
    the gunshots, which cuts against Baker’s self-defense theory. R. 140 (Trial Tr. at 108) (Page ID
    #748). And it is not proper for us to reweigh the evidence or consider the credibility of witnesses.
    Hilliard, 11 F.3d at 620. We have, moreover, previously held that the fact of aiming a gun in the
    victim’s direction and firing it “alone supports a finding of specific intent,” which is a more
    culpable mental state than malice aforethought. United States v. Grant, 
    15 F.4th 452
    , 458 (6th Cir.
    2021); see also United States v. Milton, 
    27 F.3d 203
    , 208 (6th Cir. 1994) (holding that the
    defendant acted with malice aforethought by firing two shots into the victim’s car). Baker does
    not contest that he aimed the gun at Mills and fired it. Thus there was sufficient evidence for a
    reasonable factfinder to conclude that Baker acted with malice aforethought when he shot Mills.
    IV. FALSE TESTIMONY AND BRADY
    Baker argues that the district court erred in denying his motion for discovery and an
    evidentiary hearing on the issue of whether Wagoner received an agreement for a reduced sentence
    in exchange for his testimony against Baker, and, if so, whether Wagoner testified falsely regarding
    this issue. Although discovery motions are typically reviewed for abuse of discretion, we review
    de novo claims pursuant to Brady v. Maryland, 
    373 U.S. 83
     (1963). United States v. Miller, 
    161 F.3d 977
    , 986–87 (6th Cir. 1998). “To establish a violation of Brady, the [defendant] has the
    burden of establishing that the prosecutor suppressed evidence; that such evidence was favorable
    to the defense; and that the suppressed evidence was material.” Carter v. Bell, 
    218 F.3d 581
    , 601
    (6th Cir. 2000).
    Baker’s motion was based on the fact that Wagoner, who was serving a federal sentence
    for unrelated drug offenses at the time he testified against Baker in federal court, United States v.
    Wagoner, 
    836 F. App’x 374
    , 376 (6th Cir. 2020), received a reduction in his federal sentence from
    15
    No. 22-5067, United States v. Baker
    143 months’ imprisonment to 86 months’ imprisonment on November 1, 2021, just a few months
    after testifying against Baker. R. 151 (Brady Mot. at 2) (Page ID #2782). Baker points to no
    additional information to suggest that Wagoner had an agreement with the government prior to
    testifying at Baker’s federal trial. As we have held:
    [A]lthough we do not take issue with the principle that the prosecution must
    disclose a tacit agreement between the prosecution and a witness, it is not the case
    that, if the government chooses to provide assistance to a witness following a trial,
    a court must necessarily infer a preexisting deal subject to disclosure under Brady.
    Bell v. Bell, 
    512 F.3d 223
    , 234 (6th Cir. 2008) (en banc); see also Williams v. Coyle, 
    260 F.3d 684
    ,
    707 (6th Cir. 2001) (“The mere fact that [the witnesses’] sentences were later altered is not
    evidence that a deal existed prior to their testimony at trial.”). Because Baker has provided nothing
    to suggest any agreement or understanding between the government and Wagoner prior to his
    testimony, the district court did not err in denying Baker’s discovery motion pursuant to Brady.
    V. CONCLUSION
    For the foregoing reasons, we AFFIRM Baker’s conviction.
