    2
    PILLARD, Circuit Judge: Prince Johnson, an African
    American temporary employee of the U.S. Department of
    Labor, sued the Department, claiming that it dismissed him
    from his position as a Veterans Employment Specialist
    because of his race in violation of Title VII. The district court
    saw grounds to doubt the Department’s stated justifications
    for Johnson’s dismissal, but granted summary judgment to the
    Department for want of evidence of racial discrimination. We
    affirm on the slightly different ground that, on the evidentiary
    record, no reasonable juror could find that the Department’s
    stated, nondiscriminatory reasons for dismissing Johnson
    were not its real reasons.
    I.
    In April 2006, the Department of Labor hired Johnson as
    a Veterans Employment Specialist within the Veterans
    Employment and Training Services (VETS) division.1 The
    Director of Operations and Programs, Gordon Burke,
    recruited Johnson, a former Army Captain, and hired him into
    a noncompetitive position for qualified veterans with service-
    related disabilities. See 5 U.S.C. § 3112; 5 C.F.R. §
    316.402(b)(4). The post was a temporary one with a
    possibility of permanent employment. 5 U.S.C. § 3112; 5
    C.F.R. § 316.402(b)(4). Pamela Langley, the Division Chief
    of the Employment and Training Programs Division within
    VETS, also interviewed Johnson and reviewed his
    application.     Langley then became Johnson’s direct
    1
    The statement of facts is taken from the record evidence submitted
    in support of the parties’ summary judgment briefing. Some of the
    facts reported here are disputed, but our obligation at the summary
    judgment stage is to view all facts in the light most favorable to the
    nonmoving party, here the plaintiff. Facts unfavorable to him that
    are included are those that Johnson has not factually controverted.

    supervisor.   Director Burke, like Johnson, is African
    American, and Division Chief Langley is white.
    Johnson’s career at VETS was short lived. He held the
    position on a temporary basis, with an extension, for
    approximately six months before Director Burke terminated
    his appointment. To Johnson, the new job was a frustrating
    disappointment. Johnson testified at his deposition that he
    had assumed he would be given adequate time and training to
    learn the skills the position required; instead, he felt, he was
    “set up to fail.” J.A. 192. His supervisors struck him as
    unfriendly and unreceptive. Johnson’s coworkers told a
    similar story: They told Johnson or averred in connection
    with discovery in this case that they observed supervisors talk
    down to Johnson, yell at him, and call him “stupid” or
    “useless.” J.A. 293, 298. One co-worker found Division
    Chief Langley “demeaning” in her interactions with Johnson,
    J.A. 45, another described a general attitude of disrespect
    toward minority employees within the office, and another
    observed instances in which Langley or Patrick Hecker, the
    VETS “Jobs for Veterans” State Grants Lead and a white
    male, yelled at Johnson.
    Johnson’s primary responsibility was to assist Hecker to
    create and update spreadsheets tracking information in the
    “Jobs for Veterans” grants program that VETS administered.
    He also worked with Ed Davin, a Performance Specialist on
    contract to VETS. Burke, Langley, Hecker, and Davin all
    perceived Johnson as struggling to complete the tasks
    assigned to him. According to their accounts, they clarified
    what was expected, identified specific deficiencies, and
    explained how he could correct them. They authorized
    Johnson to spend some time at a VETS State Local Office in
    Maryland to learn more about how the program worked in
    practice, and they arranged for VETS to sponsor Johnson for
    4
    training to upgrade his relevant skills. In the face of some
    disagreement from Johnson about which courses would be
    most appropriate, the supervisors authorized him to take an
    Excel training course and sent him to a training conference in
    Chicago.
    Despite what management characterized as efforts to
    make Johnson’s employment work out, in October 2006,
    Division Chief Langley recommended to Director Burke that
    Johnson’s probationary appointment be terminated. As
    Langley recounts the situation, her own observations of
    Johnson’s work and the reports of his direct supervisors
    persuaded her that he should not remain in the position.
    Langley notified Johnson that she was going to recommend
    termination of his employment at VETS for failure to perform
    satisfactorily and for his “unacceptable attitude” when
    advised of errors in his work product. J.A. 221. Burke agreed
    with Langley’s recommendation. He recounted that he
    terminated Johnson “based on [his] own dissatisfaction with
    [Johnson’s] argumentative demeanor and his reported lack of
    performance and argumentative character.” J.A. 207. In the
    Termination Memorandum Burke issued to Johnson, he
    outlined the requirements of Johnson’s position and then
    listed the ways in which Johnson’s performance had been
    deficient: He had “not completed satisfactorily” the projects
    he had been assigned and had shown an “argumentative
    response and demeanor” when confronted with his poor work.
    J.A. 473.
    After exhausting his administrative remedies, Johnson
    brought suit in district court, alleging that he was subjected to
    a hostile work environment based on his race, and that his
    termination was racially discriminatory in violation of Title
    VII. Following discovery, the district court granted summary
    judgment to the government on both claims. Johnson v.
    5
    Perez, 
    66 F. Supp. 3d 30
    , 45-46 (D.D.C. 2014). The
    Department moved this court for summary affirmance. The
    court granted the Department’s motion in part, affirming
    judgment on the hostile work environment claim on the
    ground that, as a matter of law, the incidents Johnson
    identified in support of that claim “were not ‘sufficiently
    severe or pervasive to alter the conditions of the victim's
    employment and create an abusive working environment.’”
    Johnson v. Perez, No. 15-5034, 
    2015 WL 5210265
    (D.C. Cir.
    July 1, 2015) (per curiam) (quoting Harris v. Forklift Sys.,
    Inc., 
    510 U.S. 17
    , 21 (1993)). The panel denied summary
    affirmance as to the discriminatory discharge claim, 
    id., which was
    then calendared for full briefing and argument to
    this panel.
    II.
    We review a district court’s grant of summary judgment
    de novo. Calhoun v. Johnson, 
    632 F.3d 1259
    , 1261 (D.C. Cir.
    2011). By the time a party files a summary judgment motion,
    all parties should have had the opportunity to investigate the
    case thoroughly and should have done so. In making or
    opposing a summary judgment motion, a party may no longer
    rely on the hope of new testimony or additional documents
    other than what it put before the court. Each party’s hand is
    dealt. The task of the court is to review the factual material
    the parties present in support of and opposition to the motion,
    in light of the parties’ legal claims and defenses, and assess
    whether the record contains disputes calling for resolution by
    a factfinder. In considering a motion for summary judgment,
    the court views the evidence in the light most favorable to the
    nonmoving party (here, Johnson) and draws all reasonable
    inferences in his favor. 
    Id. The court
    may not make
    credibility determinations or otherwise weigh the evidence.
    
    Id. The court
    may not, for example, believe one witness over
    6
    another if both witnesses observed the same event in
    materially different ways. But if one party presents relevant
    evidence that another party does not call into question
    factually, the court must accept the uncontroverted fact.
    Summary judgment is appropriate only if “there is no
    genuine dispute as to any material fact and the movant is
    entitled to judgment as a matter of law.” FED. R. CIV. P.
    56(a). That can be the case when, for example, the parties
    agree about the facts—what happened—and the court accepts
    the movant’s view of the legal implications of those facts, or,
    as in this case, when a putatively disputed body of evidentiary
    material could not, even assuming a sympathetic factfinder,
    reasonably support a finding crucial to the nonmoving party’s
    legal position. A dispute about a material fact is “‘genuine’ . .
    . if the evidence is such that a reasonable jury could return a
    verdict for the nonmoving party.” Anderson v. Liberty Lobby,
    Inc., 
    477 U.S. 242
    , 248 (1986). In that circumstance, the
    summary judgment motion must be denied. 
    Id. A moving
    party is entitled to judgment, however, if the nonmoving party
    “fails to make a showing sufficient to establish the existence
    of an element essential to that party’s case, and on which that
    party will bear the burden of proof at trial.” Celotex Corp. v.
    Catrett, 
    477 U.S. 317
    , 322 (1986).
    Title VII prohibits federal agencies from discriminating
    against their employees on the basis of race, color, religion,
    sex, or national origin. 42 U.S.C. § 2000e-16(a). Federal
    employees’ Title VII claims, although authorized by a
    separate statutory section, are analyzed in the same way as
    Title VII claims against private employers. See, e.g., Borgo v.
    Goldin, 
    204 F.3d 251
    , 255 n.5 (D.C. Cir. 2000). Under the
    burden-shifting framework of McDonnell Douglas, a Title VII
    plaintiff seeking to prove disparate treatment through indirect,
    circumstantial evidence “must first establish a prima facie
    7
    case of prohibited discrimination.” Aka v. Wash. Hosp. Ctr.,
    
    156 F.3d 1284
    , 1288 (D.C. Cir. 1998) (en banc); see
    McDonnell Douglas Corp. v. Green, 
    411 U.S. 792
    , 802
    (1973). Once the plaintiff has done so, the burden then shifts
    to the defendant to “articulate legitimate, nondiscriminatory
    reasons for the challenged employment decision.” 
    Aka, 156 F.3d at 1288
    .
    The Department’s position is that it terminated Johnson
    because his performance was deficient and his demeanor was
    argumentative in response to supervisor feedback. At
    summary judgment, when an employer has offered a
    legitimate, non-discriminatory reason for the challenged
    termination, as the Department has done in this case, the
    court’s inquiry turns to “one central question: Has the
    employee produced sufficient evidence for a reasonable jury
    to find that the employer’s asserted non-discriminatory reason
    was not the actual reason and that the employer intentionally
    discriminated against the employee on the basis of race, color,
    religion, sex, or national origin?” Brady v. Office of the
    Sergeant at Arms, 
    520 F.3d 490
    , 494 (D.C. Cir. 2008). In the
    posture in which this case comes to us, our focus is on
    whether a jury, looking at the record evidence and drawing all
    inferences in Johnson’s favor, could conclude that Johnson’s
    race was “a motivating factor” for the discharge. 42 U.S.C. §
    2000e-2(m).
    Johnson has failed to identify record evidence from
    which a reasonable jury could conclude that race played a role
    in his discharge. Had Johnson been able to show that Burke
    gave conflicting justifications for his recommendation, or that
    the reasons he gave were not credible based on the underlying
    facts of Johnson’s job performance, Johnson might have
    raised a material factual dispute. For example, evidence that
    similarly-situated, non-black employees with comparable
    8
    performance deficits were not fired was what sufficed in
    Wheeler v. Georgetown University Hospital, 
    812 F.3d 1109
    ,
    1115 (D.C. Cir. 2016), to create a triable factual dispute about
    the employer’s assertedly nondiscriminatory reliance on
    plaintiff’s poor job performance. In Ridout v. JBS USA, LLC,
    
    716 F.3d 1079
    , 1084 (8th Cir. 2013), plaintiff’s evidence that
    he was meeting his employer’s expectations up to the time of
    termination, and that the employer’s response to his alleged
    insubordination was unduly harsh when measured under the
    employer’s own general policy and practice of responding to
    such problems, sufficed to create material factual disputes
    about the employer’s invocation of performance and behavior
    problems. And in the case perhaps most akin to this one,
    White v. Baxter Healthcare Corp., 
    533 F.3d 381
    , 394-95 (6th
    Cir. 2008), evidence that plaintiff’s educational and
    experiential qualifications were superior to those of the
    candidate offered the promotion plaintiff sought provided
    context for the employer’s reliance on an “inherently
    subjective determination” of applicant’s “aggressive”
    interview demeanor—a factor “easily susceptible to
    manipulation”—and sufficed to create a material factual
    dispute whether the employer’s assertions were a pretext for
    racial discrimination. This record, however, does not present
    evidence from which a reasonable jury could find either that
    Johnson’s job performance was better than the Department
    claims, or that his supervisors’ stated concerns about
    Johnson’s unresponsiveness to constructive criticism are
    unworthy of credence.
    The Termination Memorandum Burke issued to Johnson
    explained that he recommended dismissal because Johnson
    had failed to “[m]aintain accountability over projects
    commensurate with [his] level of responsibility,” had been
    unable “to accomplish routine tasks on a reoccurring [sic]
    basis under [his] own initiative,” and had not “[i]nterface[d]
    9
    positively with fellow staff members and [his] supervisor.”
    J.A. 473. Burke gave no conflicting justifications for his
    decision.     In ensuing explanations, Burke sometimes
    emphasized one reason more than the others, but he gave no
    contrary account of Johnson’s job performance, nor any other,
    conflicting reason.
    All of the record evidence memorializing Burke’s
    justifications for terminating Johnson is consistent. The
    record of Burke’s interview with an Equal Employment
    Opportunity Counselor, Burke’s affidavits of April 2007 and
    August 2007, and Burke’s July 2012 deposition reflect a
    decision based on Johnson’s failure to do the job proficiently
    and his resistance to feedback when his supervisors tried to
    work with him to improve. In an interview with an Equal
    Employment Opportunity Counselor, Burke explained that
    “Johnson [could not] do the work.” J.A. 482. In an affidavit
    dating from April 2007, Burke explained both that Johnson
    had been unable to complete the assigned work and that
    Burke had been dissatisfied with Johnson’s demeanor. In an
    August 2007 affidavit, Burke again noted Johnson’s
    argumentative and disruptive behavior with supervisors.
    Finally, in his July 2012 deposition, Burke explained,
    “Johnson was terminated because he could not perform the
    requirements of the job position and because of his inability to
    get along with peers and superiors characterized by an
    argumentative demeanor.” J.A. 98.
    Johnson attempts to show contradiction by pointing to the
    Department’s answer to Johnson’s complaint, which admitted
    that “Mr. Burke stated that he terminated Mr. Johnson to
    support the supervisor and because Mr. Johnson could not
    perform the work,” but denied that those statements were
    conflicting. J.A. 27. Johnson sees a conflict between Burke’s
    two bases but, as the district court noted, “it stands to reason
    10
    that a part of Burke’s support for Johnson’s supervisor
    (Langley) might very well be support for her assessment that
    Johnson was unable to do the work required for his position in
    a timely fashion and without errors.” 
    Johnson, 66 F. Supp. 3d at 39
    . There is no contradiction between acting in support of
    another manager’s assessment of an employee under her
    supervision and acting based on the factual accuracy of that
    assessment.
    Nor is there any evidence calling into question the factual
    basis for Burke’s conclusion that Johnson’s job performance
    was inadequate. Johnson attempts to show that he performed
    well at his job and that he did not have an argumentative
    demeanor. Neither attempt to call Burke’s justifications into
    question raises a genuine issue of material fact.
    First, although there is record evidence that Johnson
    performed well in some areas, there is no evidence
    contradicting Burke’s conclusion that Johnson could not
    perform his assigned tasks at the level expected of someone in
    his role. Johnson’s evidence consists of (1) statements of his
    non-supervisory colleagues, Angela Freeman and Loretta
    Alston; and (2) an affidavit of team leader Hecker. None of
    those witnesses’ accounts raises a material factual dispute
    about Burke’s justifications.
    The accounts of Johnson’s colleagues, Freeman and
    Alston, fail materially to dispute Burke’s justifications.
    Angela Freeman, a Management Analyst and the leader of a
    team that worked with Johnson’s, averred, “Given my grade I
    was never in the position to assign Mr. Johnson work,
    however as [stated] above he and I often teamed up [to]
    complete various projects within the agency. The instances in
    which Mr. Johnson assisted me with the completion of a
    project I observed his work to [be] excellent and extremely
    11
    timely in manner.” J.A. 298. Because Freeman never
    supervised or even saw the work that Johnson did on his own,
    her statements cannot call into question Burke’s conclusion
    that Johnson was not sufficiently accurate, timely, and
    accountable for his assigned tasks.
    Loretta Alston, also a Management Analyst and another
    of Johnson’s co-workers, testified “I don’t know” how well
    Johnson did his job. J.A. 35. But she said that when Johnson
    showed her “how to do the spreadsheets” he “was very
    competent.” J.A. 36. Like Freeman, Alston was not in a
    position to judge how quickly or accurately Johnson
    performed on the tasks that the program’s management
    assigned to him. That Johnson appeared competent to Alston
    while he trained her does not call into question Burke’s
    conclusion that Johnson persistently failed, in Burke’s own
    view and that of Johnson’s other supervisors, to complete his
    work without error or delay.
    Finally, the affidavit of team leader Hecker, with whom
    Johnson was assigned to work directly, supports Burke’s
    conclusions without contradiction. Hecker noted that Johnson
    “worked well when assigned to coordinate and interact with
    others to complete an assignment.” J.A. 231. “[H]owever,”
    Hecker stated, “the majority of the work was individual work
    and involved information or data which had to be entered into
    spreadsheets or other automated and internet based systems. .
    . . Often the spreadsheets that [Johnson] created or modified
    contained easily identified errors when reviewed.” 
    Id. Hecker also
    noted Johnson’s failure to complete projects on
    deadline, 
    id. at 231-32,
    and his lack of the “knowledge or
    organizational skills required of the position,” 
    id. at 231.
    Hecker’s affidavit is fully consistent with Burke’s conclusion
    that Johnson was unable to complete his work on his own.
    12
    Nor has Johnson presented any evidence calling into
    question Burke’s conclusion that Johnson was argumentative
    in his interactions with his supervisors. The accounts of
    Johnson’s supervisors support Burke’s conclusion. Hecker,
    who had a quasi-supervisory relationship to Johnson, averred
    that when he tried to bring Johnson’s “marginal work” to his
    attention, Johnson “would become defensive.” J.A. 232.
    Johnson’s first-line supervisor, Langley, also found Johnson
    argumentative. Langley testified: “It seemed to me that at
    times he was argumentative, particularly when I requested
    that he change something or . . . when I identified that there
    was a deficiency in what he had provided me, he would
    become argumentative in responding . . . . So in that way he
    was argumentative. He didn’t seem to accept criticism of his
    work, constructive criticism of his work.” J.A. 124-25.
    That Burke in the internal EEO process described
    Johnson as a “good guy” who got along well with his
    colleagues, J.A. 482, does not contradict Burke’s conclusion
    that Johnson dealt poorly with criticism of his work and
    responded defensively and argumentatively. In Burke’s own
    interactions with Johnson, Burke recounted, Johnson “was
    argumentative with [him] on three occasions where [Johnson]
    was actually in [Burke’s] office to discuss performance.” J.A.
    99.
    Critically, the evidence Johnson puts forward in an effort
    to call into question Burke’s justification comes from
    colleagues who provide no reason to believe that they were
    Johnson’s supervisors, were in a position to assess his work
    product, or had firsthand experience trying to give Johnson
    feedback on his work. Johnson’s colleagues Alston, Jenel
    Turner, and Linda Chambers all averred that they never saw
    Johnson being argumentative at work. But Burke did not
    terminate Johnson on the ground that Johnson was generally
    13
    argumentative in the office or failed to get along with his
    office peers; there is no dispute that Johnson was affable and
    agreeable to his peers at work. See, e.g., J.A. 482. Rather,
    Burke’s justification was the compound difficulty that
    Johnson’s work was deficient and that he reacted with an
    “argumentative response and demeanor” when supervisors
    sought to address his work deficiencies. J.A. 473. The
    accounts of his colleagues, who did not interact with Johnson
    in a supervisory relationship or purport to have observed such
    interactions, do not address the quality of his work and do not
    suffice to controvert the testimony of his supervisors so as to
    create a genuine factual dispute whether Johnson was
    argumentative and defensive when confronted with feedback.
    In sum, Johnson has not presented evidence from which a
    reasonable jury could conclude that the nondiscriminatory
    reasons Burke gave for terminating Johnson’s employment
    were not his real reasons. The record evidence does not show
    that Burke gave conflicting justifications or that Burke’s
    justifications were unsupported by the underlying facts of
    Johnson’s employment. Johnson rests his case on a pretext
    theory and has not identified other types of evidence—such as
    direct evidence, evidence of similarly-situated employees who
    were treated better than he was, or other forms of
    circumstantial evidence—tending to show that race was a
    motivating factor.
    Because the record could not support a finding that the
    Department’s justifications for terminating Johnson were
    pretext, the Department is entitled to summary judgment.
    III.
    Finally, we offer brief clarification on three points of
    potential confusion. First, it is somewhat unusual for a court
    to find—as the district court did here—that there is a triable
    14
    issue as to pretext, but no triable issue as to discrimination.
    The district court found that there was “arguably a genuine
    dispute of fact about Plaintiff’s job performance and
    workplace demeanor and, thus, whether Defendant’s
    proffered reasons for terminating Johnson were pretextual.”
    
    Johnson, 66 F. Supp. 3d at 41
    . The court nonetheless granted
    summary judgment to the Department on the ground that
    Johnson had not introduced evidence that the employer’s
    potentially pretextual reasons were a mask for racial
    discrimination. 
    Id. To be
    sure, some summary judgment
    records—including, in the district court’s view, this one—
    would permit a jury to find that an employer’s reasons are
    false, yet could not support a reasonable inference of
    discrimination. See generally St. Mary’s Honor Ctr. v. Hicks,
    
    509 U.S. 502
    , 508-09 (1993) (sustaining determination that
    defendants’ proffered reasons were not the real reasons for the
    challenged demotion and discharge, but that plaintiff failed to
    show racial motivation). The legal permissibility of such a
    disposition, however, should not be taken to suggest that a
    successful showing of pretext, without more, is necessarily
    inadequate to support an inference of unlawful racial
    discrimination. “In an appropriate case, ‘[t]he factfinder’s
    disbelief of the reasons put forward by the defendant’ will
    allow it to infer intentional discrimination.” 
    Aka, 156 F.3d at 1294
    (quoting St. Mary’s Honor 
    Ctr., 509 U.S. at 511
    ). In
    such a case, “[n]o additional proof of discrimination is
    required.” St. Mary’s Honor 
    Ctr., 509 U.S. at 511
    (quoting
    Hicks v. St. Mary’s Honor Ctr., 
    970 F.2d 487
    , 493 (8th Cir.
    1992)) (internal quotation marks and emphasis omitted).
    Neither the district court’s opinion nor ours should be read to
    suggest otherwise.
    Second, in the course of explaining that Johnson had
    failed to show that Burke’s proffered reasons for firing
    Johnson were contradictory, the district court noted that
    15
    Johnson’s only evidence was his own testimony that Burke
    had originally claimed he was firing Johnson to support
    Langley. In addition to rejecting that testimony for the reason
    we cited above—it failed to show any inconsistency—the
    court stated that “[s]uch self-serving testimony is insufficient
    to create a genuine issue of material fact regarding whether an
    employer’s proffered reason for termination was pretextual.”
    
    Johnson, 66 F. Supp. 3d at 39
    . Relying on earlier district
    court opinions, the district judge stated that “[s]elf-serving
    testimony does not create genuine issues of material fact,
    especially where that very testimony suggests that
    corroborating evidence should be readily available [but is
    absent].” 
    Johnson, 66 F. Supp. 3d at 39
    . But as we have
    explained since the earlier district court decisions, “there is no
    rule of law that the testimony of a discrimination plaintiff,
    standing alone, can never make out a case of discrimination
    that could withstand a summary judgment motion.” Desmond
    v. Mukasey, 
    530 F.3d 944
    , 964 (D.C. Cir. 2008) (quoting
    George v. Leavitt, 
    407 F.3d 405
    , 414 (D.C. Cir. 2005))
    (internal quotation marks omitted). After all, evidence a party
    proffers in support of its cause will usually, in some sense, be
    “self-serving.” It is nonetheless beyond question as a general
    proposition that parties, like other fact witnesses, are legally
    competent to give material testimony. Indeed, in many kinds
    of cases, parties are the key, or even sole, witnesses. To the
    extent the testimony of a witness who is also a party may be
    impaired by party self-interest, it is ordinarily the role of the
    jury—not the court on summary judgment—to discount it
    accordingly. See, e.g., 
    George, 407 F.3d at 413-14
    .
    Third, the district court reasoned that “unsubstantiated
    co-worker testimony alone is generally insufficient to raise a
    question of material fact regarding pretext at the summary
    judgment stage.” 
    Johnson, 66 F. Supp. 3d at 42
    . But the co-
    workers’ accounts that Johnson offered to show that he was
    16
    treated more harshly than white employees were insufficient
    not because they were the unsubstantiated testimony of co-
    workers, but because their statements either were too general
    to controvert the employer’s particular concerns about
    Johnson’s job performance or spoke to aspects of Johnson’s
    work other than what the supervisors identified as deficient,
    or both. Courts may grant summary judgment to a defendant
    where a plaintiff’s evidence is vague or conclusory. See, e.g.,
    Ransom v. Ctr. for Nonprofit Advancement, 
    514 F. Supp. 2d 18
    , 27 (D.D.C. 2007) (rejecting on summary judgment
    plaintiff’s “vague and conclusory” allegation of
    discrimination); Chung v. Wash. Metro. Area Transit Auth.,
    No. 04-0366, 
    2007 WL 1154084
    , at *3 (D.D.C. Apr. 18,
    2007) (concluding affidavits too vague to be probative), aff’d,
    268 F. App’x 6 (D.C. Cir. 2008); Carter v. Rubin, 
    14 F. Supp. 2d
    22, 42 (D.D.C. 1998) (concluding deposition testimony
    and affidavits lacked requisite specificity). But determining
    whether a co-worker’s specific and relevant, if
    uncorroborated, testimony is trustworthy is a credibility
    determination reserved for the jury.

    For the foregoing reasons we affirm the decision of the
    district court.
