    Appeal from the Superior Court
    of the District of Columbia
    (CAB-6886-15)
    (Hon. Jennifer A. DiToro, Trial Judge)
    (Argued October 8, 2019                             Decided November 19, 2020)
    David A. Branch for appellant.
    Sonya L. Lebsack, Assistant Attorney General, with whom Karl A. Racine,
    Attorney General for the District of Columbia, Loren L. AliKhan, Solicitor
    General, and Caroline S. Van Zile, Deputy Solicitor General, were on the brief, for
    appellees.
    Before GLICKMAN, BECKWITH, and MCLEESE, Associate Judges.
    GLICKMAN, Associate Judge: Appellant Godwin Ukwuani, a Nigerian-born,
    African American male, was terminated from his employment at the District of
    2
    Columbia Department of Regulatory Affairs (DCRA) in June 2015. Following his
    termination, Mr. Ukwuani sued appellees—the District of Columbia, his former
    DCRA Director Melinda Bolling, and his former supervisor, Lynn Underwood—in
    Superior Court for violations of the District of Columbia Human Rights Act
    (HRA) 1 and the District of Columbia Whistleblower Protection Act (WPA). 2
    Appellant alleged that, during his tenure at DCRA, he was reprimanded by Mr.
    Underwood and ultimately fired by Ms. Bolling because of his race and national
    origin, and in retaliation for his having complained about unlawful discrimination
    at DCRA and gross mismanagement and substantial and specific dangers to public
    safety.   He also alleged that appellees had subjected him to a hostile work
    environment because of his race and national origin.      The trial court granted
    summary judgment to appellees on all of these claims.
    On appeal, appellant contends that the court erred in disposing of his claims
    on summary judgment. He presents three overarching claims for our review. First,
    appellant claims, the trial court erred by ignoring evidence of Bolling and
    Underwood’s bias and the allegedly pretextual nature of the reason given for his
    1
    D.C. Code §§ 2-1401.01–1404.04 (2016 Repl. & 2020 Supp.).
    2
    D.C. Code § 1-615.51 et seq. (2016 Repl.).
    3
    termination, which was sufficient to allow his intentional discrimination and
    hostile work environment claims to proceed. Second, appellant claims, the court
    erroneously rejected his HRA retaliation claims for failure to show that he engaged
    in protected activity and without taking into account evidence that Bolling and
    Underwood were aware of complaints he had made regarding racial and national
    origin discrimination. Third, appellant contends that the court erred in similarly
    concluding that he failed to establish a prima facie case of retaliation under the
    WPA.
    Our independent review of the record persuades us that appellant’s
    arguments are not well taken, and that the trial court properly granted summary
    judgment to appellees on all his causes of action. We affirm the entry of judgment
    for appellees.
    I.
    A. Appellant’s Position Within DCRA
    Appellant began working at DCRA in 1999 as a general mechanical
    engineer in its Permit Operations Division (POD). The POD issues permits for all
    District building constructions and modifications.     The title of “engineer” in
    4
    appellant’s position at the POD may be misleading. Although appellant had a
    master’s degree in mechanical engineering, the position description did not require
    an engineering license (which appellant did not have) and the job mainly involved
    reviewing building permit applications submitted by architects and professional
    engineers to ensure their compliance with the requirements of the District’s
    construction codes. However, the position description also stated that reviewers
    are expected to “exercise[] independent judgment on the acceptability of plans,”
    indicating that the job might involve more than just confirming code compliance.
    Appellant generally received positive performance reviews during his tenure
    with the POD, and in 2014 he was promoted to the managerial position of
    Supervisory Mechanical Engineer in POD’s Mechanical/Plumbing Section. This
    was an at-will position, meaning that the employee’s termination was neither
    grievable nor appealable.
    In January 2015, appellee Bolling (who is African American) was named the
    Director of DCRA. Previously she had been the Department’s General Counsel.
    The following month, appellee Underwood (who is white) became the Deputy
    Chief Building Official of DCRA, a position with oversight responsibility for the
    POD, including appellant.
    5
    B. Appellant’s Disagreements with DCRA Management Regarding
    Qualifications for Plan Reviewers
    According to Bolling, upon her elevation to Director she was charged by the
    Mayor with improving the speed and efficiency of the POD by directing permit
    reviewers, like appellant, to limit their review to whether plans complied with the
    District’s building codes and refrain from otherwise evaluating or commenting on
    plan designs. 3 In March 2015, the POD recruited for a Chief Structural Engineer.
    Cognizant of the Mayor’s emphasis that POD should focus on code review,
    Bolling encouraged Gary Englebert, a white man, to apply for the position.
    Bolling had worked with Englebert before and, as she testified in her deposition,
    she “knew he had done code review in other jurisdictions.”                 Englebert’s
    qualifications also included expertise in the interpretation of the District’s building
    code and numerous International Code Council (ICC) certifications. 4           Bolling
    ultimately selected Englebert for the position over Benjamin Johnson, an African
    3
    As Director Bolling explained in her deposition testimony, “the decision
    was that the job you’re performing [in the POD] is plan review and not
    engineering. You’re not designing anything. You’re reviewing plans that have
    already been designed by a design professional licensed in the District, and you’re
    confirming that they comply with the code that’s in effect. But we can’t have you
    redesigning work from a licensed professional in the industry.”
    4
    The ICC has promulgated model construction codes, ten of which the
    District has incorporated into its building code. See 12 DCMR § 101A.
    6
    American man with a lengthy tenure at the POD and an engineering degree.
    Bolling made the hiring decision after a review panel found both applicants highly
    qualified and eligible to fill the position in light of their high review scores. 5
    Bolling chose Englebert over Johnson, she said, because of Englebert’s code
    review background and superior code review qualifications.
    Appellant disagreed with Bolling’s decision. Although he was not informed
    of Englebert and Johnson’s rankings in the application process, he believed
    Johnson was more qualified to be made Chief Structural Engineer because Johnson
    also knew the District’s building code, appellant thought highly of his work, and it
    was appellant’s view that the position should be filled by an applicant with an
    engineering degree. He orally complained to Underwood about the decision and
    said he felt that Johnson was more qualified and had been treated unfairly because
    he was African American. He added that other plan reviewers opposed Englebert’s
    selection as well. Bolling was aware of appellant’s dissatisfaction with her hiring
    decision and his belief that it was racially motivated.
    5
    In the hiring process, Mr. Johnson received an “applicant score” of 98 and
    Mr. Englebert received a score of 96; these exceeded the scores of the other
    applicants. Nothing in the record discloses what the two-point difference between
    the high scores was based on, or suggests that the difference was significant.
    7
    Appellant alleges that after Englebert was hired, Underwood discontinued
    his regular meetings with the other POD managers, all of whom were African
    American or Asian American, and spoke more frequently with Englebert.
    This was not the first time appellant expressed opposition to the
    Department’s changing views of the plan reviewer role and qualifications. Two
    years earlier, in 2013, the DCRA’s Chief Building Official, Rabbiah Sabbakhan,
    proposed to hire additional plan reviewers to fill a new position in the POD at the
    GS-13 level that would be called “inspector” rather than “engineer.”             The
    minimum qualifications for this “inspector” position included several ICC
    certifications and an associate’s degree in engineering, architecture, or construction
    technology.
    A group of foreign-born POD GS-12 plan reviewers with engineering
    degrees, including appellant, met with Sabbakhan and Bolling (who was then
    DCRA’s General Counsel) to voice objections to the “inspector” position and their
    status in relation to it. At that meeting, they requested a GS level increase on the
    grounds that their pay was not comparable to that of engineers in other District
    agencies and that the “inspector” position offered a higher salary but required a
    less advanced degree.     The group wrote a follow-up letter asserting that the
    8
    proposed “inspector” position did not require the necessary qualifications for the
    performance of plan reviewing tasks, and that the disparity in pay between their
    “engineer” positions and the new position was unfair given that they had
    bachelor’s and master’s degrees. The objectors did not mention their race or
    national origin in the meeting or in the letter; there is no evidence in the record that
    appellant or any other GS-12 engineer complained to Sabbakhan or Bolling that
    the anticipated pay differential or change in their status or professional
    responsibilities was meant to discriminate against them, or would have the effect of
    doing so, on a racial or national origin (or other invidious) basis. One of the
    objecting plan reviewers, Tesfaye Habte, was deposed and testified that he
    “d[id]n’t remember saying . . . [or] participating in . . . a complaint about
    Caucasian and non-Caucasian . . . as such, but we’ve complained about the
    differences in grade, and if it turns out that the difference in grade is a color
    difference as well, I don’t know.”
    Sabbakhan and Bolling were not persuaded by the objections. They were of
    the view that the POD plan reviewer position could not be compared with
    engineering positions in other departments because plan reviewers did not do
    engineering work; rather, they focused narrowly on whether construction and
    9
    building plans met code requirements. The new “inspector” position was approved
    with the proposed educational requirements. 6
    C. Appellant’s Relationship with Underwood
    Underwood was appellant’s direct supervisor from the time Underwood
    joined the DCRA in February 2015 until appellant was terminated in June 2015.
    By all accounts, they did not have a positive working relationship. Appellant
    contends the friction began early in Underwood’s tenure, when Underwood
    “mocked” the experience of the GS-12 plan reviewers during a meeting with
    appellant, by remarking that he could “pose five code questions to them and bet
    they could not answer correctly.” Appellant believed the remark was indicative of
    Underwood’s general contempt for the plan reviewers he managed, all of whom
    were, like appellant, foreign-born or non-white employees. In depositions, other
    plan reviewers recalled Underwood as a supervisor who often lost his temper,
    yelled at employees, and was generally demeaning or “nasty.” None of them
    attributed Underwood’s unpleasant attitude to racial or national origin bias or
    prejudice, however.
    6
    On April 27, 2015, Sabbakhan forwarded the POD plan reviewers’ 2013
    complaint letter to Underwood, with the message “FYI.”
    10
    Meanwhile, Underwood criticized appellant for not performing his
    managerial duties; according to Underwood, appellant “simply continued to do
    plan review,” allowed plans to get behind, and failed to correct behavior and
    erroneous building code calls by some plan examiners. Underwood communicated
    those criticisms to appellant by, as he put it, “verbal disciplining.” Underwood
    also formally reprimanded appellant in a so-called Letter of Counsel on April 13,
    2015, in connection with an incident in which appellant sought to review certain
    employment applications that Underwood had rejected because the applicants did
    not have ICC certifications or plan review experience. In the letter, Underwood
    characterized appellant’s conduct as an act of “insubordination.” The letter further
    criticized appellant’s performance as “less than managerial,” citing his vocal
    opposition to Englebert’s hiring and his siding with plan reviewers’ dissatisfaction
    and complaints on various matters.      Underwood recommended that appellant
    “extricate [him]self from fellow workers.” Appellant refused to sign the Letter of
    Counsel.
    D. Appellant’s Disagreements with DCRA Management Regarding Building
    Permit Approvals and His Termination
    Appellant also disagreed with his superiors over their policy of limiting
    building permit review to code compliance and their related encouragement of
    11
    expeditious approval of building plans subject to the applicant’s subsequent
    satisfaction of conditions that would need to be met instead of requiring rounds of
    corrections to be made to the plans before the POD would sign off on them.
    Appellant expressed his dissenting views on these matters in connection with at
    least three building permit applications in 2015, and appellant’s recalcitrance in a
    fourth such instance was the impetus for Bolling’s decision to terminate him.
    On January 26, 2015, Sabbakhan asked appellant to “note any conditions of
    substance” and issue the permit for a project at George Washington University that
    afternoon.   This urgency was in response to the applicant’s request, made to
    Bolling, that the approval be expedited. Appellant thought the permit required
    further discussion with the applicant and that it should have been revised, but he
    issued the permit as Sabbakhan directed him to do, with the list of items he thought
    the applicant would need to address. Appellant then sent an email to Matt Orlins, a
    DCRA attorney, in which he said he was “somehow uncomfortable with the
    instruction . . . to approve [the] application today.” The email did not explain why
    appellant was “uncomfortable” or the substance of the revisions he deemed
    necessary; appellant did not claim it was dangerous to issue the permit. Orlins
    responded that he was “not involved” in the review and that appellant should work
    with his supervisor. There is no evidence in the record that either Sabbakhan or
    12
    Bolling was informed of appellant’s email or that appellant pursued the matter
    further.
    On February 20, 2015, Sabbakhan asked appellant for an update on the
    status of a pending permit application for a project called “Union Kitchen.” It
    appears the Director had asked Sabbakhan for a “specific reason” why the permit
    had been delayed, and Sabbakhan had told her it would be resolved that day.
    Appellant responded that he wanted to check the direction of the building’s
    exhaust system in the project plans, and if that information was not indicated, he
    would ask the applicant to correct the application.       Sabbakhan rejected that
    approach and told appellant the issue was “not that complicated” and the permit
    should be approved forthwith, with any remaining issues listed as conditions to be
    enforced by way of a later inspection.       Appellant wrote back with a general
    objection to the conditional approval practice, in which he expressed his views that
    “if the conditions were not met during construction, it would be too late and costly
    by the time our inspection gets to notice,” and that the practice made code
    enforcement more difficult.
    Appellant again opposed the approval of a permit in May 2015. Englebert,
    who had assumed the position of Chief Structural Engineer by this time, had asked
    13
    appellant to review a small residential construction permit for applicants described
    (by appellant) as “a white couple.” Appellant told Englebert that the application
    was not compliant because it specified an unrealistically low construction cost of
    only $100. In response, the applicants (who apparently were on the scene and
    waiting for the permit to be issued) crossed out the $100 and wrote in $1,000, but
    appellant was not satisfied and refused to approve the permit because the new
    figure was, in his view, “just guesswork.” In addition, appellant believed the
    project design was not compliant with zoning regulations. Appellant’s actions
    were reported to Underwood, who allegedly yelled at him for his refusal to
    approve the permit.
    The final incident unfolded in June, when appellant reviewed plans to
    renovate a basement for use as a hair salon or barber shop. On June 10, appellant
    had a lengthy and apparently contentious meeting with the architect for the plan,
    Eric Peterson. During that meeting, appellant insisted that the construction was a
    change to the building’s use and required a separate HVAC system that would flow
    to the basement. Peterson disagreed with the need for that change. Appellant told
    him he could take the matter up with Underwood.             Peterson did so, and
    Underwood agreed with him rather than with appellant. Later that afternoon,
    Peterson again attempted to secure appellant’s approval of the plan with
    14
    Underwood’s support. The three men discussed the issue in person, and appellant
    continued to insist that a separate HVAC system was required.        In response,
    Underwood yelled at appellant and stated that nothing in the building code
    required the design change. This argument took place in an open space within the
    POD, and several other employees heard it. Appellant eventually approved the
    plan after his “further assessment determined that the design (arrangement) would
    be adequate.”
    The next morning, on June 11, 2015, Underwood e-mailed a request to the
    human resources division to take disciplinary action against appellant.        He
    proposed a suspension and potentially termination.     That same day, appellant
    emailed his version of the argument to Sabbakhan and Bolling, insisting that he
    had been right to question Peterson’s plans and complaining that Underwood had
    verbally abused him in front of colleagues.
    On June 12th, Underwood received a heated letter from Peterson
    complaining about appellant’s handling of his application. Peterson wrote that he
    was “seriously inconvenienced” by the incident on June 10th; he felt he had lost a
    day of work to appellant’s need to “prove that he was right” and have his “ego”
    15
    validated by a permit applicant. Underwood discussed the incident with Bolling,
    and he provided her with a copy of Peterson’s letter.
    Bolling terminated appellant on June 24, 2015.              In her deposition, she
    testified that she did so because the letter “had the ring of truth,” and it
    demonstrated appellant’s “poor customer service” when his job was to “mak[e] the
    process better.” Though Bolling said Peterson’s letter was the catalyst for
    appellant’s termination, she also stated that her decision was informed by reports
    from Underwood and Sabbakhan that appellant had been slow to adapt to his role
    as a manager of plan reviewers and resistant to the policy of focusing on code
    compliance without “redesign[ing] plans submitted by applicants.”                   She
    maintained, however, that she had not considered termination an appropriate action
    against appellant until after she had read Peterson’s letter. 7
    II.
    We review the trial court’s grant of appellees’ motion for summary
    judgment de novo, undertaking an “independent review of the record” and
    7
    Bolling testified that this was not the only instance in which she
    terminated a manager at the DCRA on account of a “customer” complaint. On a
    later occasion, she did it again; in that instance, the manager was white.
    16
    evaluating it in the light most favorable to appellant. 8 If we conclude there is any
    record evidence, after discovery, on which a jury could properly reach a verdict for
    appellant, we must reverse the grant of summary judgment. 9 But while appellant is
    entitled to “the benefit of every reasonable inference from the evidence,” he is not
    entitled to “inferences based on guess or speculation.” 10 Allegations that are
    unsupported or conclusory are “insufficient to establish a genuine issue of material
    fact to defeat the entry of summary judgment.” 11
    A. HRA – Discriminatory Termination Claim
    We start by addressing appellant’s claim that his termination was the result
    of, or motivated by, discrimination on the basis of his race or national origin. The
    HRA prohibits employers from taking an adverse action against their employees
    “wholly or partially for a discriminatory reason based upon . . . race [or] . . .

    national origin.” 12 At the summary judgment stage, we typically evaluate an
    employee’s claim of such intentional discrimination using the three-part burden-
    shifting framework set forth in McDonnell Douglas Corp. v. Green. 13 Under that
    framework, the employee has the initial burden to state a prima facie claim, which
    raises a rebuttable inference of intentional discrimination that the employer may
    counter by articulating a legitimate, non-discriminatory rationale for the adverse
    action. 14 If the employer advances such a rationale, the inference of discrimination
    “drops from the case,” leaving the employee with the task of showing that the non-
    discriminatory reason provided by the employer is false and that the employer’s
    action actually was motivated, in whole or in part, by a discriminatory reason. 15

    an inference of discrimination.” (internal quotation marks omitted)).

    for its actions, “we need not pause to analyze whether [appellant] made out a prima
    facie case of [discrimination] in opposing summary judgment.” 16
    Appellees produced evidence that appellant was terminated for a legitimate,
    non-discriminatory reason—namely, his conduct in the incident that generated the
    Peterson letter. Therefore, the question on appeal now is whether a jury could
    infer that discrimination motivated appellant’s termination, based on “the
    combination of (1) [his] prima facie case; (2) any evidence [he] presents to attack
    [appellees’] proffered explanation for [their] actions; and (3) any further evidence
    of discrimination[.]” 17
    The trial court found that appellant presented evidence on which a jury could
    find that the Peterson letter was not the sole reason for terminating him, in that
    Bolling also cited her conversations with Underwood and Sabbakhan regarding
    appellant’s managerial difficulties and resistance to expediting code review.
    Nonetheless, the court awarded summary judgment to appellees. Appellant claims
    this ruling was erroneous in two respects. First, he argues that the trial court’s
    findings regarding an alternative explanation for his termination demonstrate that
    16
    Id. at 353
    .
    17
    Id. at 354. 19
    appellees’ stated rationale was pretextual and that this showing of “pretext” was
    enough to permit a jury to infer that the real reason for his termination was
    discriminatory. Second, he contends that the court ignored circumstantial evidence
    that Underwood and Bolling harbored a racial bias against him. Neither of these
    contentions persuades us that a jury could properly find that Bolling terminated
    appellant for a discriminatory reason based, in whole or in part, on his race or
    national origin.
    First, appellant misapprehends the significance of the court’s assessment that
    a jury could find that Bolling had additional reasons for terminating him besides
    the Peterson letter. A showing by a plaintiff of a prima facie case and a triable
    issue as to the truth of the employer’s proffered justification is not always enough
    to overcome a motion for summary judgment. The Supreme Court has explained
    that “an employer would be entitled to judgment as a matter of law if the record
    conclusively revealed some other, nondiscriminatory reason for the employer’s
    decision, or if the plaintiff created only a weak issue of fact as to whether the
    employer’s reason was untrue and there was abundant and uncontroverted
    evidence that no discrimination had occurred.” 18 This is such a case. What the
    18

    530 U.S. 133
    , 148 (2000)
    (emphasis added).
    20
    trial court perceived (and we conclude the record confirms) is simply that a jury
    could     find   additional   nondiscriminatory   reasons   supporting   appellant’s
    termination; there is a fatal lack of evidence from which a jury fairly could infer
    that those were not, individually or in combination, the true reasons and that
    appellant’s termination really was motivated or informed by discriminatory
    animus.
    Preliminarily, we think it most doubtful that a jury reasonably could
    disbelieve Bolling’s testimony that she terminated appellant on account of the
    Peterson incident merely because she acknowledged the other management
    concerns with appellant reported by Underwood and Sabbakhan. Bolling was
    definite and unwavering in her testimony that she was motivated by what she
    called Peterson’s “extremely detailed” account of his frustrating and unpleasant
    experience with appellant, and that she “counted all the problems that [Peterson]
    had encountered as a customer dealing with someone that was supposed to [be]
    making the process better.” The record also indicates that Bolling did not consider
    firing appellant before she received the Peterson letter, and that she had also
    terminated a white employee for similar customer service complaints. But even if
    we assume that Bolling was motivated at least in part by Underwood’s and
    Sabbakhan’s concerns with appellant’s performance, those concerns were
    21
    themselves legitimate, non-discriminatory rationales for his termination that do not
    support a finding of discrimination. While appellant disputes the merits of their
    criticisms of him and asserts that his job continued to necessitate design review, his
    unsupported opinion on these matters is insufficient to raise a disputed issue of fact
    as to whether appellees’ justifications for his termination were false. 19 On this
    record, there is no evidence that could lead a reasonable jury to conclude that
    appellees are “making up or lying about the underlying facts that formed the
    predicate for the employment decision.” 20
    Furthermore, appellant also has not proffered other evidence from which a
    jury fairly could infer that the real motivations behind his termination included

    termination, “discrimination may well be the most likely alternative explanation;”

    racial or national origin discrimination. Nothing in the record suggests that Bolling
    displayed or had a discriminatory animus toward appellant or any other non-white
    or foreign-born employee. 21 Appellant argues that even if Bolling herself was not
    biased, her decision to terminate him was infected by the bias of a subordinate,
    Underwood, on whose reports and recommendations she allegedly relied.
    Appellant points to three facts for which there is record support that he contends
    create a triable issue on Underwood’s motivations. In our view, however, even
    assuming arguendo that appellant could show Underwood impacted the decision
    by Bolling to terminate him (as he must in order to prove he was fired because of a
    subordinate’s bias), 22 the record demonstrates only a contentious and
    unprofessional relationship between appellant and Underwood. It does not support
    a finding that discriminatory animus underlaid the tension between them.
    21
    Appellant’s contrary argument, made for the first time in his reply brief,
    that the trial court ignored evidence that Bolling displayed a willingness to
    discriminate when she encouraged Mr. Englebert, a white man, to apply for and
    ultimately selected him as DCRA’s Chief Structural Engineer, does not persuade
    us of a triable issue of fact. While a decision maker’s prior discriminatory acts can
    be used as “background evidence in support of a [discrimination] claim,” Nat’l
    R.R. Passenger Corp. v. Morgan, 
    536 U.S. 101
    , 113 (2002), there is no evidence
    that Englebert’s selection had to do with his race rather than his significant code
    review experience.
    22
    See 
    Furline, 953 A.2d at 355-56
    .
    23
    First, appellant argues that Underwood’s disrespectful statements about the
    GS-12 plan reviewers, such as his disparaging remark that they could not answer
    questions about the building code correctly, is circumstantial evidence of
    discrimination. We are not persuaded. The evidence may support a picture of
    Underwood as an ill-tempered and offensive manager who was dissatisfied and at
    odds with the employees he supervised. That is not enough to support a plausible
    inference that Underwood was motivated by discriminatory animus. Offensive and
    insulting remarks need not explicitly invoke a racial (or other invidious)
    classification to constitute evidence of discrimination—“[t]he speaker’s meaning
    may depend on various factors including context, inflection, tone of voice, local
    custom, and historical usage” 23—but the record in this case evinces no such
    contextual or historical link between Underwood’s criticisms of his staff and his
    staff’s race or national origin. Underwood’s comments may have been rude or
    worse, but they related to job performance and there is no evidence showing that
    Underwood meant them as a racially or ethnically charged insult or that the
    comments were motivated by prejudice.
    23
    Ash v. Tyson Foods, Inc., 
    546 U.S. 454
    , 456 (2006).
    24
    Second, appellant cites Underwood’s criticism of him for expressing and
    supporting the complaints and concerns of the engineers whom he supervised as
    evidence of bias. This is not, however, a case in which a jury reasonably could
    draw the inference that Underwood harbored discriminatory attitudes and animus
    against appellant for his advocacy on behalf of a protected class. 24 The nub of the
    dispute was the agency’s shift away from design review to focus on expeditious
    code compliance, for reasons and with consequences unrelated to the employees’
    membership in a protected class, and appellant’s perceived failure, in his role as a
    manager, to support the agency’s (and not his subordinates’) objectives. There is
    no evidence that Underwood would have responded differently to appellant’s
    support of his employees had those employees been white, and notably, no
    witness-employee in this case perceived Underwood’s management as racially or
    otherwise biased.
    Third, appellant cites evidence that, after Englebert was hired, Underwood
    stopped having regular meetings with non-white POD managers and instead
    primarily communicated with them through Englebert. We see little significance
    24
    See, e.g., Ramsey v. Am. Air Filter Co., 
    772 F.2d 1303
    , 1310 (7th Cir.
    1985) (notation on black plaintiff’s job application that he was arrested for
    marching in a civil rights demonstration was probative evidence of employer’s
    discriminatory intent).
    25
    in this isolated fact. Underwood’s utilization of Englebert as an intermediary may
    have been entirely benign and understandable, since Englebert was vested with
    supervisory authority over at least some other POD employees (apparently
    including appellant).     But even if Underwood’s practice was some (slight)
    evidence of cronyism or favoritism, it does not show that Underwood had an
    unlawful motivation for ending the meetings or seeking to undermine appellant
    because of his race or national origin. 25
    While we generally disfavor the resolution of intentional discrimination
    claims on summary judgment “since they almost always involve issues concerning
    the employer’s (or supervisor’s) motive or intent” 26 (generally a question “ill-
    suited for determination as a matter of law” and better left for the fact finder 27),
    this is a case in which summary judgment is appropriate, because appellant has
    failed to present even circumstantial evidence of discrimination.

    B. HRA – Hostile Work Environment
    To prevail on a hostile work environment claim under the HRA, a plaintiff
    must establish “(1) that he is a member of a protected class, (2) that he has been
    subject to unwelcome harassment, (3) that the harassment was based on
    membership in a protected class, and (4) that the harassment is severe and
    pervasive enough to affect a term, condition, or privilege of employment.” 28 The
    trial court correctly concluded that appellant failed to submit probative evidence of
    at least the third prong—as discussed above, the record on summary judgment does
    not demonstrate that Underwood’s quarrelsome relationship with appellant was
    based on or related to appellant’s protected class status.
    C. HRA – Retaliation
    The HRA prohibits an employer from retaliating against an employee “for
    opposing an employment practice that is prohibited by the Act.” 29 To make out a

    that a causal relationship existed between that adverse action and the protected
    activity. 30
    “Whether actions by an employee constitute protected activity is a question
    of law.” 31 For an activity to be “protected” under the Act, (1) it must be one in
    which an employee expresses a “reasonable good faith belief” 32 that their employer
    violated the HRA; and (2) the employer must be aware of the activity; that is, the
    employee must “alert the employer that [they are] lodging a complaint about
    allegedly discriminatory conduct.” 33

    class, for such practices, however repugnant they may be, are outside the purview
    of the HRA.”).
    28
    However, because appellees produced evidence that appellant was
    terminated for a legitimate, non-discriminatory reason, we need not fixate on
    whether appellant made out a prima facie case of retaliation. 34 Instead, just as we
    did when analyzing appellant’s discrimination claim, “we may proceed to answer
    the ultimate question”: whether a jury could find that retaliation motivated
    appellant’s termination, based on a combination of appellant’s prima facie case,
    evidence rebutting appellees’ proffered reasons for their actions, and any further
    evidence of retaliation. 35
    On appeal, appellant maintains that the trial court overlooked three instances
    in which he complained about racial discrimination at DCRA and thus engaged in
    a protected activity: (1) his 2013 complaint regarding the creation of the GS-13
    “inspector” position; (2) his efforts to present to management the concerns of the
    “foreign-born engineers” in the POD; and (3) his complaint that the hiring of Gary
    Englebert over Benjamin Johnson was racially motivated. 36

    35
    See supra notes 16 & 17 and accompanying text.
    36
    At oral argument in this appeal, appellant identified his June 11, 2015
    email communication to Bolling and Sabbakhan regarding Underwood’s treatment
    of him during the Peterson incident as a fourth protected activity for purposes of
    his retaliation claim. Out of fairness to the appellee, we generally do not consider
    (continued…)
    29
    First, appellant contends that the evidence at summary judgment showed that
    he “implicitly complained of race and national origin discrimination” at DCRA
    when he and other foreign-born GS-12 plan reviewers objected in 2013 to the
    proposed GS-13 “inspector” position. The record, however, demonstrates that the
    GS-12 reviewers, including appellant, did not even implicitly lodge a complaint
    that the new position was unlawfully discriminatory. It is true that several GS-12
    reviewers said in their depositions that there was a racial difference between them
    and the GS-13 “inspectors.” But no reviewer testified that this difference was the
    subject of a complaint. As one reviewer testified, he “d[id]n’t remember saying
    . . . [or] participating in . . . a complaint about Caucasian and non-Caucasian . . . as
    such, but we’ve complained about the differences in grade.” And appellant, in his
    own deposition, described the qualifications of the GS-13 position as unfair to him
    and the other GS-12 reviewers because they required an ICC certification and did
    not privilege their advanced degrees. The letter the reviewers sent is consistent
    with this view.
    (continued…)
    a claim raised by an appellant for the first time at oral argument. See Jung v. Jung,
    
    844 A.2d 1099
    , 1112 n.9 (D.C. 2004). At any rate, the email raises no complaint
    of practices prohibited by the HRA, nor does it connect Underwood’s treatment of
    appellant to his race or national origin. It could not have alerted appellees to any
    unlawfully discriminatory conduct, and hence did not constitute protected activity
    under the HRA. See 
    Green, 652 A.2d at 46
    .
    30
    These complaints certainly raised an objection to the disparity in pay created
    between their position and the GS-13 position that required no advanced degree,
    but “there is no sign” that appellant or the other GS-12 reviewers connected “the
    inequality to any difference” between their race or national origin and those who
    they believed would be considered for the GS-13 position. 37 Even if appellant
    believed that the new position discriminated against the GS-12 reviewers because
    of race or national origin, his actual complaint to his employer did not reveal any
    such belief; thus, the 2013 complaint was not a protected activity under the HRA
    and it cannot support appellant’s retaliation claim.
    Second, appellant’s argument that Underwood advocated for his termination
    so that appellant could no longer represent the interests of other foreign-born plan
    reviewers fails for the same reason—his “advocacy” was on behalf of employees
    who happened to be members of a protected class, but he did not link his advocacy
    to their national origin. Objections to agency “policies, or mistreatment in general,
    37

    (employee could not show a protected activity
    where she did not link her lower pay in comparison to newly hired employees to a
    difference in their ages); cf. McFarland v. George Washington Univ., 
    935 A.2d 337
    , 360 (D.C. 2007) (doubting that an employee’s letter voicing “general
    dissatisfaction with the fact that he was passed over for [a] promotion” was a
    protected activity, though affirming award of summary judgment to employer on
    other grounds).
    31
    without connecting it to membership in a protected class . . . are outside the
    purview of the HRA.” 38
    The missing connection is not supplied by an interrogatory answer cited by
    appellant, in which appellees concede “[u]pon information and belief” that
    appellant verbally complained “that African-American employees including [Mr.]
    Johnson were being treated unfairly” and that Director Bolling was “aware that he
    had complained of discrimination within DCRA.” Although interrogatory answers
    can help establish a genuine issue of material fact, 39 not every interrogatory answer
    is created equally. Several circuits do not even consider interrogatory answers
    based “upon information and belief” when ruling on summary judgment motions,
    because they do not meet the requirement under Fed. R. Civ. P. 56(c)(4) that
    affidavits submitted in opposition to summary judgment must “be based on

    our local rule, Super. Ct. Civ. R. 56(c)(4), given that it is identical to its federal
    counterpart. 41 This not to say that we will not consider appellees’ interrogatory
    answer. After all, it might be admissible against the defendants at trial as the
    admission of a party-opponent. 42     But admissible evidence is not necessarily
    sufficient evidence; “[t]he mere existence of a scintilla of evidence in support of
    the plaintiff’s position will be insufficient to defeat a motion for summary
    judgment.” 43

    33
    The phrase “upon information and belief” raises sufficiency concerns,
    because it is nothing more than a bare profession of belief despite a lack of
    knowledge as to the truth of the belief. It forces us to ask what “information” the
    “belief” is based upon. The answer does not cite any specific documentation or
    other support, but appellant references two instances that purportedly corroborate
    it: appellant’s complaint regarding the hiring of Mr. Englebert over Mr. Johnson,
    and appellant’s “voicing [of] staff mistreatment.” While the former is a claim of
    racial discrimination, the latter is not; the record only shows that appellant
    “expressed outrage with how [he] perceive[d] staff have been mistreated,” not that
    they were being mistreated because of their race or national origin. Consequently,
    we conclude that even if the interrogatory answer is admissible, it is insufficient to
    establish that appellant complained about racial discrimination against anyone
    other than Mr. Johnson.
    Lastly, appellant cites his complaint about the selection of Englebert over
    Johnson for the Chief Structural Engineer position as a protected activity. 44 It is
    44
    Appellant does not attempt to connect this complaint to his termination,
    but argues that, at least partly in response to this activity, Underwood issued the
    Letter of Counsel against him. Because we conclude that appellant’s objection to
    Englebert’s hiring is not a protected activity, we express no view on the separate
    question whether the Letter was a materially adverse action under the HRA.
    34
    undisputed that appellant told Underwood he believed Johnson was more qualified
    for the position and that he thought the selection of Englebert was an instance of
    racial discrimination.   Appellees argue, however, that this was not protected
    activity because the record shows that appellant did not have a reasonable good
    faith belief that discriminatory hiring occurred, and the point was not in material
    dispute. We agree with appellees on this point.
    The “reasonable good faith belief” test is not a high bar. It asks only
    whether the employee reasonably and sincerely believed when they made the
    report that unlawful discrimination occurred. 45 If so, the employee is protected
    from retaliation even if the belief was mistaken and the employer’s conduct was
    lawful, for the HRA’s goal of rooting out workplace discrimination “relies heavily
    on the initiative of aggrieved employees, whose efforts in the public interest would
    be severely chilled if they bore the risk of [retaliation] whenever they were unable
    45
    See, e.g., 
    Green, 652 A.2d at 46
    ; Moyo v. Gomez, 
    40 F.3d 982
    , 984 (9th
    Cir. 1994) (“An erroneous belief that an employer engaged in an unlawful
    employment practice is reasonable, and thus actionable . . . , if premised on a
    mistake made in good faith. A good-faith mistake may be one of fact or of law.”);

    669 F.2d 1179

    inquiry in a retaliation case.”); Parker v. Balt. & Ohio R. Co.,

    , 1019
    (D.C. Cir. 1981).
    35
    to establish . . . the merits of their claims.” 46 Generally speaking, a plausible
    complaint that a more qualified member of a racial minority was passed over for a
    position in favor of a less qualified white applicant does suggest the existence of a
    reasonable and good faith belief that discriminatory hiring took place, even if the
    complainant turns out to be wrong about the relative merits of the applicants, 47 and
    will be sufficient to trigger the anti-retaliatory protections of the HRA.
    But the context of this case distinguishes it. For present purposes, we
    assume that appellant made his charge of racial discrimination in good faith.
    Nonetheless, appellant did not have, and has never articulated, an objectively
    reasonable basis for accusing DCRA of such discrimination in selecting Englebert
    over Johnson to head the POD. He failed to show a material dispute on this issue.
    It is undisputed that Director Bolling made the hiring decision after a review panel
    found both applicants to be highly qualified and eligible to be selected by her in
    light of their high review scores (96 for Englebert and 98 for Johnson). It is

    .
    47
    Cf. Brown v. Nat’l Acad. of Sciences, 
    844 A.2d 1113
    , 1123 (D.C. 2004)
    (employees will make out a prima facie case of discrimination in hiring if they can
    show (1) they belong to a protected class; (2) they were qualified for the position;
    (3) their “failure to be hired occurred despite [their] employment qualifications;”
    and (4) the decision not to hire them was based on their protected class status).
    36
    undisputed that she selected Englebert because of his superior code review
    qualifications, which was the area where supervision of the POD was deemed most
    needed. Appellant has pointed to no evidence that the review panel’s criteria were
    discriminatory, or applied discriminatorily in this instance, or that Bolling’s stated
    reason for picking Englebert was not her real reason.
    Appellant’s longstanding disagreement on the merits with DCRA’s
    emphasis on code review over engineering skills in selecting a head of the POD
    did not provide a reasonable basis for his charge of racial discrimination. The
    record shows that the determination to prioritize code review skills and
    deemphasize engineering skills in this area was a legitimate and non-
    discriminatory policy decision made to address a serious deficiency in the POD’s
    performance of its main function. Appellant has pointed to no evidence to the
    contrary. And appellant clearly knew that DCRA officials, including Bolling,
    believed code review experience was critical and that engineering skills were
    secondary. They had been emphasizing that policy for years; it was, after all, the
    subject of appellant’s 2013 complaint about the GS-13 plan reviewer position—he
    disagreed with Bolling and Sabbakhan’s view then that the POD needed reviewers
    with ICC certifications more than it needed them to have engineering degrees. In
    other words, appellant was aware that there was a legitimate, sufficient, non-
    37
    discriminatory reason for Englebert’s selection, and the record does not show that
    appellant had a basis to dismiss that reason as pretextual. 48
    Moreover, appellant did not have (and still does not have) a sound basis to
    assert that Johnson was materially more qualified than Englebert. Having made no
    inquiry into the actual hiring process, appellant was unaware how the two
    applicants had been evaluated or how they scored. Their virtually identical review
    scores would seem to imply, if anything, that they were equally qualified to fill the
    position. Certainly, appellant has failed to show that the two-point difference was
    significant, or that it would have made his belief in discrimination any more
    48
    Indeed, appellant proffered no evidence, other than his own unsupported
    opinion, that engineering degrees really were more valuable in the plan reviewer
    role than other qualifications, which conceivably might have lent support to a
    reasonable belief that Bolling had made up a pretextual basis for hiring Englebert.
    See, e.g., 
    Estenos, 952 A.2d at 893-94
    (factual dispute regarding job qualifications
    created a triable issue of fact on whether a termination was pretextual). Nor did
    appellant argue to his employer that their preference for applicants with ICC
    certifications disproportionately excluded non-white or foreign born applicants,
    which might have supported a reasonable belief that DCRA’s hiring policy had an
    unlawful disparate impact on those applicants, see, e.g., Ricci v. DeStefano, 
    557 U.S. 557
    , 578 (2009) (“Under the disparate-impact [theory] a plaintiff establishes a
    prima facie violation by showing that an employer uses a particular employment
    practice that causes a disparate impact on the basis of” a protected class.), and
    there are no facts in the record to suggest this was the case.
    38
    reasonable had he known of it. 49 And the record indicates that both candidates had
    long experience, the big difference being that Englebert’s experience was focused
    on code review, which is what the DCRA deemed most important. At his
    deposition, appellant himself conceded that Englebert had acquired over thirty ICC
    certifications, while he did not know whether Johnson had obtained any. There
    appears to be no evidence in the record that Johnson in fact had acquired any ICC
    certification or other accreditations testifying to his code review expertise.
    In sum, an accusation of racism is a very serious charge. For it to be
    objectively reasonable it is not enough that it is leveled in good faith. Such an
    accusation cannot be called objectively reasonable when, as here, the accuser (1)
    knows that the challenged decision has a genuine and legitimate non-
    discriminatory rationale, (2) beyond that, has made no reasonable inquiry into the
    merits of the decision or the process by which it was made, and (3) has no basis for
    accusing the decision makers of any discriminatory animus or bias. We conclude
    49
    At least one circuit has held that information not known to the employee
    cannot support the reasonableness of an employee’s belief of employer
    misconduct. Clover v. Total System Services, Inc., 
    176 F.3d 1346
    , 1352 (11th Cir.
    1999) (analyzing a Title VII retaliation claim). We need not reach that issue in this
    case.
    39
    there is insufficient evidence that appellant reasonably believed the hiring of
    Englebert violated the HRA for his retaliation claim to survive summary judgment.
    D. Whistleblower Protection Act
    The WPA protects District employees from “retaliation or reprisal” when
    they, in the public interest, “report [government] waste, fraud, abuse of authority,
    violations of law, or threats to public health or safety.” 50 In order to state a prima
    facie WPA claim, a plaintiff must show (1) that they made a disclosure protected
    by the Act; (2) that a supervisor “took or threatened to take a prohibited personnel
    action” or otherwise retaliated against them; and (3) that the protected disclosure
    “was a contributing factor to the retaliation or prohibited personnel action” (i.e. the
    protected disclosure and the prohibited personnel action are causally connected). 51
    A “protected disclosure” is defined to include (as pertinent here) “any
    disclosure of information . . . to any person by an employee . . . that the employee
    reasonably believes evidences,” among other things, “gross mismanagement,” a
    “violation of federal, state, or local law, rule, or regulation,” or a “substantial and

    , 924 (D.C. 2008).
    40
    specific danger to the public health and safety.” 52 The employee must hold such a
    belief at the time the whistle is blown, and the belief must be both sincere and
    objectively reasonable. 53 Appellant claims he made protected disclosures that
    supported his WPA retaliation claim by (1) objecting to or refusing to approve the
    permit applications described above by GWU, Union Kitchen, Mr. Peterson, and a
    “white couple;” (2) complaining that Englebert was hired unlawfully; and (3)
    complaining about the GS-13 “inspector” position.
    In granting summary judgment to appellees, the trial court concluded that
    appellant had failed to proffer sufficient evidence from which a jury could find that
    he stated a prima facie case under the WPA. Specifically, the court ruled that (1)
    appellant did not make protected disclosures when he objected to three of the
    permit approvals and charged that Englebert had been hired unlawfully; and (2)
    appellant had not established that either his 2013 complaint regarding the GS-13
    “inspector” position or his January 2015 complaint concerning the GWU permit

    , 1276 (D.C. 2020)

    41
    (assuming they were protected disclosures) was linked to a retaliatory or adverse
    personnel action. Appellant argues that all those rulings were incorrect as a matter
    of law, and that his WPA claim therefore should proceed to trial. For the following
    reasons, we are not persuaded to reverse the trial court’s judgment in favor of
    appellees on this claim.
    1. Appellant’s Alleged Protected Disclosures
    Appellant argues that his objections to approving the plans submitted by
    Peterson, Union Kitchen, and the “white couple” were protected disclosures that
    raised issues of gross mismanagement, “violations of D.C. rules,” and a substantial
    and specific danger to public safety. He maintains that approving construction
    permits in those instances without first requiring design or other changes meant
    approving plans with dangerous flaws and prevented the department from
    resolving code violations before construction on a project began.
    We assess the reasonableness of appellant’s belief under the “disinterested
    observer test,” which asks whether “a disinterested observer with knowledge of the
    essential facts known to and readily ascertainable by the employee reasonably
    42
    [could] conclude that the actions of the government evidence illegality?” 54 This
    analysis does not “hinge[] upon whether the [action] was ultimately determined to
    be illegal,” but it does require that the employee’s belief be objectively reasonable
    and that the employee has not ignored essential facts, including those “which
    detract[] from a ‘reasonable belief.’” 55     “In other words, the fact finder must
    consider whether the employee reasonably should have been aware of information
    that would have defeated his inference of official misconduct.” 56
    While appellant frames his complaints regarding the permits as sounding an
    alarm about the risks of the agency’s focus on code compliance review rather than
    design evaluation, the record does not support a finding that appellant had a
    “reasonable and genuine contemporaneous belief” that the approvals in question
    posed real safety concerns to the District or meaningfully impeded POD’s ability
    to regulate building construction and modification. 57        He conceded to his
    54

    60 A.3d 1131
    , 1151 (D.C. 2012) (quoting Zirkle v. District of
    Columbia, 
    830 A.2d 1250
    , 1259-60 (D.C. 2003) (alterations omitted). This court
    adopted the “disinterested observer test” from federal authorities interpreting the
    “similarly worded” federal WPA. See 
    Zirkle, 830 A.2d at 1260
    n.13.

    supervisors, for example, that his “further assessment determined” Peterson’s
    basement design to be “adequate,” belying his contention on appeal that the design,
    or the process by which it was approved, was unsafe. 58 And his complaints
    regarding the Union Kitchen permit and the “white couple’s” residential
    construction permit merely raised vague concerns that conditional approvals would
    prove “costly” (to whom, it is unclear) to correct and that “guesswork” in a private
    individual’s own construction costs would somehow cheat the government. 59
    Appellant opposed an agency policy that favored performing an expeditious
    code review, noting issues of substance, and approving the permits conditioned on
    making the code corrections identified in the review. This was a policy about
    58
    Appellant raises the additional argument that the basement needed a
    separate ventilation system according to District law. He has cited no law or
    regulation to us indicating that is the case, and both his supervisor and Peterson
    clearly disagreed with his interpretation. On this record, the dispute appears to be
    nothing more than a “[d]ebatable difference[] of opinion,” and thus does not rise to
    the level of a protected disclosure. District of Columbia v. Poindexter, 
    104 A.3d 848
    , 855 (D.C. 2014).
    59
    These complaints stand in marked contrast to the authorities appellant
    cites as support for his contention that he made protected disclosures about the
    safety and soundness of POD’s permitting policies. In those cases, plaintiffs raised
    specific complaints about the “serious and potentially life-endangering problems”
    with a manager’s response to a fire, see Coleman v. District of Columbia, 
    794 F.3d 49
    , 58 (D.C. Cir. 2015), or reported such waste of funds that a jury could conclude
    that a District project was “just burning money,” see Williams v. Johnson, 
    776 F.3d 865
    , 871 (D.C. Cir. 2015).
    44
    which reasonable people can disagree; in fact, appellees argue that the policy is
    consistent with that of other jurisdictions. A mere policy disagreement with an
    agency or supervisor is not enough to show either gross management or a
    substantial and specific danger to public safety; an employee “must disclose such
    serious errors by the agency that a conclusion that the agency erred is not debatable
    among reasonable people.” 60 Appellant’s “purely subjective perspective” on the
    agency’s permitting process is insufficient for a reasonable jury to conclude that he
    made a protected disclosure under the WPA. 61
    Appellant further argues that he presented evidence sufficient to establish
    that when he complained to Underwood about the Englebert hiring, he reasonably
    believed the hiring decision was racially motivated or an act of preferential
    treatment and a violation of District law. Our reasons for rejecting this contention
    overlap with our reasons for rejecting his similar HRA retaliation claim.
    Appellant’s claims of racial discrimination and preferential treatment in the
    Englebert hiring do not pass the disinterested observer test, because the objective
    merits of Englebert’s hiring were either known or “readily ascertainable” to

    appellant. As previously discussed, at the time of his selection, appellant knew
    that the DCRA was moving in a direction that privileged Englebert’s code
    expertise and background. Appellant’s assertion that Johnson was clearly more
    qualified was out of touch with a disinterested observer’s view as to whom the
    agency reasonably and fairly could hire.
    2. “Disclosures” Regarding the GS-13 “Inspector” Position and
    the GWU Permit Approval
    Appellant characterizes as protected disclosures his communications with
    Bolling and Sabbakhan in which he opposed the creation of the new GS-13
    “inspector” position, and his email to DCRA attorney Matt Orlins stating that the
    GWU permit made him “somehow uncomfortable.”              The trial court assumed
    arguendo that these complaints were protected disclosures, but concluded that
    appellant had failed to show that they contributed to any prohibited personnel
    action taken against him. While we doubt a jury could find either was a protected
    disclosure, 62 we affirm the award of summary judgment on the grounds on which
    the trial court relied.
    62
    As discussed above, there is no record support for appellant’s claim that
    his opposition to the GS-13 position was a protected disclosure because it raised an
    issue of disparate treatment of POD reviewers based on their national origin. And
    appellant’s email stating that he was “somehow uncomfortable” with a
    (continued…)
    46
    The two-year lapse between appellant’s complaints regarding the creation of
    the GS-13 position and his termination is fatal to his argument that those events
    were linked, 63 and while the record shows that Underwood was made aware of the
    2013 complaint by April 27, 2015, there is no evidence that the Letter of Counsel
    (given to appellant on April 13, 2015), appellant’s termination (which occurred
    two months later), or any other reprimand by Underwood bore any relation to
    appellant’s 2013 advocacy.
    As for appellant’s email about the GWU permit, the trial court correctly
    concluded that there was no causal connection between it and any prohibited
    personnel action, because there is no evidence that appellees were aware of the
    disclosure. 64 Appellant sent his email only to Mr. Orlins, and Bolling could not

    supervisor’s directive to approve a particular permit application was in all
    likelihood too vague to alert its addressee that appellant believed there was gross
    mismanagement or a substantial and specific danger to public safety.

    See 
    Freeman, 60 A.3d at 1144-45
    (noting that “while the temporal
    proximity of an adverse personnel action to a protected disclosure may lend
    support to an inference of a causal relationship, ‘a stretch of over two years
    realistically cannot constitute temporal proximity in the ordinary sense of that
    phrase’”) (quoting Johnson (Michelle) v. District of Columbia, 
    935 A.2d 1113
    ,
    1120 (D.C. 2007)).
