    Plaintiff Terence J. Hayes (“plaintiff”) brings this action against defendant
    Carolyn W. Colvin, Commissioner of the Social Security Administration (“defendant” or
    “Commissioner”) pursuant to 42 U.S.C. § 405(g), seeking reversal of the
    Commissioner’s denial of his application for Social Security Disability Insurance and
    Supplemental Security Income benefits. See Comp]. [Dkt. #1]. Now before the Court
    are plaintiff’ 3 Motion for Judgment of Reversal [Dkt. #11] and defendant’s Motion for
    Judgment of Affirmance [Dkt. #13]. For the reasons set forth below, the Court DENIES
    plaintiff’s Motion, GRANTS defendant’s Motion, and DISMISSES this case.
    BACKGROUND
    1. Legal Framework and Procedural History
    Plaintiff applied to the Social Security Administration (“SSA”) for Disability
    Insurance Benefits (“DIB”) and Supplemental Security Income (“$81”) on January 7,
    2011 and May 18, 201 1, respectively, alleging numerous maladies. See Administrative
    Record (“AR”) at 134-41 [Dkt #8]. To qualify for $81 and DIB, a claimant must
    demonstrate that he is unable to “engage in any substantial gainful activity by reason of
    any medically determinable physical or mental impairment” that “has lasted or can be
    expected to last for a continuous period of not less than 12 months.” 42 U.S.C. §
    423(d)(l)(A). Plaintiffcontends that he meets this statutory definition. His multi—year
    quest for disability benefits, however, has proven unsuccessful. See AR at 89-102.
    After the Commissioner denied his initial petitions, plaintiff requested, and received,
    review by an Administrative Law Judge (“ALJ”). See AR at 42-88. This too, failed.
    AR at 19-36. The ALJ’s decision became the final decision of the Commissioner on
    May 29, 2014, AR at 5, and, shortly thereafter, plaintiff sought judicial review from this
    Court, see Complaint.
    11. Administrative Record
    The ALJ’s decision was based on the following administrative record.1 On
    October 17, 201 1, approximately three years after the purported onset of his disability,
    plaintiff saw District of Columbia Adult Protective Services therapist Sophia Lenk, CP,
    M.S.W., who evaluated plaintiff for hoarding tendencies and obsessive thoughts. AR at
    229. At his initial visit, plaintiff displayed a “preoccupation with getting SSDI
    ' Plaintiff's alleged disability onset date is October 31, 2008. However, because plaintiff did
    not seek treatment until 201 l, the administrative record reflects only those medical records
    generated beginning in 2011.
    physicians, they need not accept medical opinions that are either internally inconsistent
    or contradicted by substantial evidence in the record. See 20 CPR. §§ 404.1527(c)(2),
    416.927(c)(2); Williams v. Shalala, 
    997 F.2d 1494
    , 1498 (DC. Cir. 1993) (“The treating
    physician’s opinion regarding an impairment is usually binding on the fact-finder unless
    contradicted by substantial evidence.” (citation and internal quotation marks omitted».
    The ALJ here determined that the opinions of Doctors Kasaci, Walseman, and Ball had
    less probative value than the opinions of Ms. Lenk and Dr. Montiero, whose findings he
    deemed supportable. See AR at 28, 31-33. After careful review of the record, I find
    nothing untoward about these assessments.
    There are, as the ALJ pointed out, substantial inconsistences between Doctors
    Kasaci and Walseman’s medical observations and their respective conclusions about
    plaintiff's functional abilities. Dr. Kasaci noted, for example, that plaintiff exhibited
    “logical” thought content and “intact” judgment. AR at 268. Never, over the course of
    plaintiff‘ 5 treatment, did Dr. Kasaci find evidence of suicidal ideation or hopelessness.
    See AR at 253, 255, 263, 268. In fact, according to Dr. Kasaci, plaintiff exhibited “no
    gross psychotic features” whatsoever. AR at 257. To the contrary, plaintiffs mental
    state stabilized over the course of treatment, prompting Dr. Kasaci to increase his GAF
    score from 45 to 50. Compare AR at 268, with AR at 253. As such, Dr. Kasaci’s
    conclusion in October 2012 that plaintiff was unable to meet numerous competitive
    standards, is perplexing, to say nothing of contradictory. See AR at 277-78.
    11
    Dr. Walseman’s opinion is plagued by the same inconsistencies. Dr. Walseman
    noted during her examinations that plaintiff had an “okay” mood with only “slightly
    restricted” affect, no overt psychosis or suicidal ideation, and exhibited “fair” insight and
    judgment. See AR at 340, 342, 344, 346, 348. She routinely categorized plaintiff’s
    depression as either “mild” or in “remission.” and consistently assessed plaintiff’s GAF
    score at 65. See AR at 340. 345, 346, 349. Contrary to her opinion in January 2013
    that plaintiff was unable to meet competitive standards in several key areas, Dr.
    Walseman’s observations evidence mild, not debilitating, cognitive limitations. See AR
    at 374—76.
    For the same reasons, the ALJ properly accorded Dr. Ball’s opinion less weight
    than Dr. Monteiro’s opinion. See AR at 31-32. Indeed, Dr. Ball’s May 2012 report
    that plaintiff’ s impairments left him unable to work is belied by his clinical findings.
    His medical notes from May 2012 indicate that plaintiff had normal reflexes, peripheral
    pulses, and muscle strength. See AR at 261, 265. The doctor opined, moreover, that
    plaintiff had only “moderate” restrictions on his ability to perform daily activities. AR
    at 248. Dr. Ball’s subsequent conclusion that plaintiff would be unable to work for the
    next year is simply not supported by his observations. See AR at 248. In fact, Dr.
    Ball’s findings are more consistent with Dr. Monteiro’s opinion that plaintiff had few
    physical limitations, and, in any event, nothing that prohibited light exertion. See AR at
    238.
    12
    In light of this record, I see no reason to disturb the ALJ’s determination that the
    opinions of Doctors Kasaci, Walseman, and Ball were unduly influenced by plaintiffs
    subjective allegations of pain. In rendering his opinion, the ALJ acknowledged all of
    the medical opinions in the record and adequately explained his reasoning. Simply put,
    the AL] did, as factfinder, precisely what he was supposed to do, and, because his
    findings are buoyed by substantial evidence. the Court must, and will, defer to his
    assessments.
    B. Plaintiff’s Credibility
    Plaintiff 5 second contention is that the ALJ misjudged his credibility. P1.’s
    Mem. at 20—22. Once again, I disagree. Not only was the ALJ entitled to adjudge
    plaintiff incredible, but he was justified in doing so. The SSA prescribes a two-step
    process for determining whether an individual has symptoms that affect his ability to
    perform basic work activities. 20 CPR. §§ 404.1529, 416.929. First, the plaintiff
    must adduce “medical signs or laboratory” findings evidencing “medically determinable
    impairment(s) that could reasonably be expected to produce” the alleged pain. Id. §§
    404. l 529(c)(1), 416.929(c)(1). Second, the ALJ must determine whether the applicant’s
    allegations of pain are “consistent with the objective medical evidence.” Id. §§
    404.1529(a), 416.929(a). Plaintiff disputes only the ALJ’s finding under the second
    prong of this inquiry.
    13
    After reviewing the record as a whole, the ALJ determined that “while severe
    conditions exist, the objective findings simply do notjustify the disabling limitations that
    [plaintiff] alleges in his testimony.” AR at 31. The ALJ further concluded that
    plaintiff’s “disability could only be based upon subjective symptoms which the
    undersigned finds are not fully credible” in light of his “potential malingering” and
    3
    “untoward motives.’ AR at 31. This determination is eminently supportable. Plaintiff
    made numerous overtures for disability benefits. As early as 2011, plaintiff exhibited a
    “preoccupation with getting approved for SSDI” that led one healthcare provider to
    conclude that he “manipulates community resources to his advantage.” AR at 229.
    Plaintiff‘s obsession intensified, and he continued to seek disability benefits on the basis
    of mental illness, but denied, in the same breath, having any cognitive difficulties
    whatsoever. See AR at 225, 227. This proved to be a common refrain. Plaintiff
    informed Dr. Kasaci in April 2012 that he was “obsessed” with procuring disability
    benefits, AR at 268, and later that same year, that he expected to have “a home in DC
    and a vacation home in Florida once he [received] his SSDI,” AR at 298. These are not
    the machinations of a truly credible man. Thus, 1 cannot conclude, as plaintiff would
    have me do, that the ALJ’s assessment was erroneous. In fact, based plaintiff‘s history
    of malingering, and blatant attempts to “manipulate community resources,” 1 see no
    reason to disturb the ALJ’s credibility determination.
    l4
    II. ALJ’s Step Four Determination
    Plaintiff next argues that the ALJ erroneously determined at step four that he was
    capable of performing a full range oflight work before November 7, 2011. Pl.’s Mem.
    at 22—23. I disagree. At step four, an ALJ must determine whether a claimant’s
    impairments prevent him from performing his past work. 20 CPR. §§ 404.1520
    (a)(4)( iv), 416.920(a)(4)(iv). The burden of proof at this stage rests entirely with the
    plaintiff. See Bowen v. Yuckert, 482 US. 137, 146 n.5 (1987). Plaintiff, however, fell
    far short of his obligation. Although he claims that the ALJ failed to consider whether
    he was able to meet the mental demands of his previous job, Pl.’s Mem. at 23, the
    reality is that plaintiff presented no evidence whatsoever of his mental state prior to
    November 7, 201 1. Plaintiffs attempt, moreover, to superimpose evidence of his 201 1
    psychiatric conditions on a nonexistent record from 2008 is a novel, to say nothing of
    improper, request. See Pl.’s Reply Mem. at 2 [Dkt.#15]. Subsequent medical findings
    simply cannot be used, as plaintiff would have this Court do, to caulk deficiencies in the
    administrative record. Accordingly, because plaintiff has not demonstrated that he was
    unable to meet the demands of his prior job, I defer to the ALJ’s finding that he was
    indeed capable of doing so until November 7, 201 1. See AR at 33-34.
    Ill. ALJ’s Step Five Determination
    Plaintiff s final objection is to the ALJ’s conclusion at step five that he retained
    the functional capacity to perform jobs that exist in the national economy. See Pl.’s
    15
    Mem. at 23-24. The ALJ’s step five determination here was based in large measure on
    the testimony ofa vocational expert. See AR at 34-36. ALJs may freely rely on the
    opinion of a vocational expert that has a full and accurate understanding of the record.
    See 20 C.F.R. §§ 404.1566(e), 416.966(e). The ALJ must not, however, rely on such
    testimony if the ALJ fails to accurately describe the claimant’s physical impairments in
    any question he poses to the expert. See Butler, 353 F.3d at 1005-06; Simms, 877 F.2d
    at 1050.
    Plaintiff claims that the vocational expert’s testimony here is misleading because
    it was based on responses to the ALJ’s hypothetical questions that omitted the opinions
    of Drs. Kasaci, Walseman, and Ball. See Pl.’s Mem. at 24. In support of his argument,
    plaintiff relies on case language stating that “hypothetical questions addressed to the
    vocational expert [should] encompass all relevant impairments of the claimant.” See
    Pl.’s Mem. at 24 (quoting Sloan v. Astrue, 
    538 F. Supp. 2d 152
    , 155 (D.D.C. 2008)).
    This case law, however, should not be misunderstood. The clear directive is not to
    present to vocational experts the minutia of every purported malady. Fairly understood,
    “relevant impairments” mean only those impairments that were relevant to the ALJ’s
    RFC assessment—z’.e., impairments established by a credible body of evidence. See
    Lockard v. Apfel, 
    175 F. Supp. 2d 28
    , 33 (D.D.C. 2001) (“[A] hypothetical question to
    the vocational expert [must] present a faithful summary of the treating physician’s
    diagnosis unless the ALJ provides good reason to disregard that physician’s
    16
    conclusions”); see also Pinkney v. Astrue, 
    675 F. Supp. 2d 9
    , 19 (D.D.C. 2009) (“[O]nly
    the impairments that the ALJ has found to be credible need to be discussed in the
    hypotheticals”). The vocational expert’s testimony here accounted for precisely that
    Indeed, both of the hypotheticals that the ALJ posed to the vocational expert tracked his
    RFC determination. See AR at 84-85. Each took into account plaintiffs challenges
    with interpersonal contact, memory, and cognition, and accounted, moreover, for
    plaintiff‘s ability to perform “light” physical labor. See AR at 85. That the vocational
    expert’s opinion accounted only for evidence that the ALJ found to be medically
    supportable is not only proper, it is perfectly reasonable. I therefore conclude that the
    ALJ’s step five determination is supported by substantial evidence.
    CONCLUSION
    Thus, for the foregoing reasons, the Court GRANTS defendant’s Motion for
    Judgment of Affirmance, DENIES plaintiff‘s Motion for Judgment of Reversal, and
    DISMISSES the case. An Order consistent with this decision accompanies this
    Memorandum Opinion.
    l7
    approved,” leading Lenk to conclude that plaintiff was “[m]alingering” and
    “manipulat[ing] community resources to his advantage.” AR at 229. According to
    Lenk, plaintiff's behavior, affect, and memory were otherwise within “normal limits.”
    AR at 230. During an October 31, 201 l appointment with Lenk, plaintiff was once
    again fixated on obtaining disability benefits for mental illness despite his belief that he
    had no such affliction. AR at 225. During his final session with Lenk on November 7,
    2011, plaintiff continued to “obsess[] over being approved for SSA” but was otherwise
    “pleasant” and “future-focused.” AR at 223. Lenk diagnosed plaintiff with
    “malingering” and 0CD, but opined that further crisis therapy was unnecessary. AR at
    223.
    On April 1 l. 2012, plaintiff sought treatment from psychiatrist Arda Kasaci, MD.
    for “anxiety, homelessness and assistance with his disability.” AR at 268. Plaintiff,
    who admitted to being “obsessed” with obtaining disability benefits, informed Dr.
    Kasaci that he had moved to Washington DC. to “try his disability” claims. AR at 268.
    Plaintiff denied feelings of hopelessness or suicidal ideation, leading Dr. Kasaci to
    conclude that plaintiff exhibited “logical” thought content, as well as “intact” memory
    and judgment. AR at 268. Nonetheless, based on plaintiff’s anxious mood and
    circumstantial thought process, Dr. Kasaci diagnosed plaintiff with OCD and anxiety
    disorder, and assessed him with a Global Assessment of Functioning (“GAF”) score of
    45.2 AR at 268-69. During a July 5, 2012 follow-up visit with Dr. Kasaci, plaintiff
    continued to have “obsessive thoughts about 881,” but reported “fewer anger episodes”
    and felt neither hopeless nor suicidal. AR at 255. On September 6, 2012, Dr. Kasaci
    increased plaintiffs anti—depressant dosage and reassessed plaintiff’s GAF at 50. AR at
    253.
    On October 31, 2012, Dr. Kasaci completed a medical source statement for
    plaintiff, noting that he had a “limited but satisfactory” ability to execute short and
    simple instructions, but “seriously limited" abilities to understand and remember simple
    instructions, to maintain attention for two-hour segments, to work with others, and to
    make simple work-related decisions. AR at 277-78. In light ofthese difficulties, Dr.
    Kasaci opined that plaintiff was “unable to meet competitive standards” in several
    functional areas, including remembering work procedures, sustaining an ordinary
    routine, and maintaining socially appropriate behavior. AR at 277-78.
    Between September 2012 and January 2013, plaintiff sought psychiatric treatment
    from Dr. Kathryn Walseman, M.D. On September 24, 2012, Dr. Walseman diagnosed
    plaintiff with anxiety disorder, but nonetheless assessed his GAF score at 65 in light of
    his “organized” thought processes and “fair"judgment.3 See AR at 348-49. Dr.

    Walseman saw plaintiff four additional times in November and October 2012, but did
    not find any changes in plaintiffs mental state or GAF score.4 See AR at 340, 342,
    344—45, 346. On January 14, 2013, Dr. Walseman completed a medical statement,
    opining that plaintiff was “seriously limited but not precluded” from remembering work
    procedures, executing short instructions, maintaining attention for two-hour segments,
    sustaining an ordinary routine without special supervision, and making simple
    work-related decisions. AR at 375-7 6. She further stated that plaintiff was “unable to
    meet competitive standards” in several functional areas, including working at a
    consistent pace and responding appropriately to criticism from supervisors. AR at
    375-76.
    In addition to his psychiatric issues, plaintiff complained of hip, knee, and spinal
    problems. On November 21, 201 1, an x-ray of plaintiff s left hip revealed no evidence
    of fracture, dislocation, or “significant” degenerative changes. AR at 232. Shortly
    thereafter, on November 26, 201 1, plaintiff visited Dr. Glen Monteiro, M.D., for a
    physical examination. See AR at 234-38. Based on his examination, Dr. Monteiro
    concluded that plaintiff had a limited range of motion in his spine, shoulders, and hips,
    Manual ofMental Disorders — Text Revision (DSM—IV-TR) 32, 34 (4th ed. 2000)).
    4 Indeed, during his October 15, 2012 appointment, plaintiffs mood was “about the same,” and
    although his “affect was slightly restricted,” plaintiff appeared “cooperative,” with “regular”
    speech, and “intact” cognition. AR at 344. During his November 12, 2012 follow-up
    appointment, plaintiff informed Dr. Walseman that he was “feeling a bit better.” AR at 340.
    Dr. Walseman assessed his mood as “overall better,” found no “overt paranoia or delusions,”
    and opined that his cognition was “intact” and his insight and judgment were “fair.” AR at
    340.
    see AR at 239, but characterized plaintiffs condition as “unimpressive overall,” AR at
    237. Dr. Monteiro further opined that although plaintiff exhibited “some limitations
    with stooping, crouching, [and] bending,” plaintiff could stand and walk for up to six
    hours a day, sit for up to six hours a day, and could “occasionally” lift and carry up to 10
    pounds and “frequently” lift and carry less than 3 pounds. AR at 238. State agency
    physician Dr. Michael Hartman, M.D., concurred with this assessment and found, upon
    completing a physical residual functional capacity assessment, that plaintiff could
    “occasionally” lift or carry 20 pounds, “frequently” lift or carry 10 pounds, and could
    stand, walk, or sit for six hours of an eight-hour workday. AR at 94.
    Plaintiff also saw Dr. Robert Ball, MD. for his back and hip problems. Based on
    his initial visit with plaintiff in March 2012, Dr. Ball diagnosed plaintiffwith “low back
    syndrome” and COPD, but otherwise found plaintiffs physical exam to be within normal
    limits. See AR at 274. When Dr. Ball next examined plaintiff on May 2, 2012, he once
    again found plaintiff's condition unremarkable. See AR at 265. In his subsequent May
    31, 2012 report, Dr. Ball opined plaintiff had only “moderate” restrictions on his social
    skills, concentration, and daily activities, and was capable of sitting for about 6 hours of
    a typical work day. AR at 248. Notwithstanding these “moderate” limitations, Dr. Ball
    concluded, in the same report, that plaintiff’ 5 medical condition would prevent him from
    working for the next calendar year. AR at 248.
    III. ALJ’s Disability Determination
    The ALJ here applied a five—step sequential evaluation to determine whether, ,
    based on the administrative record, plaintiff was entitled to 881 and DlB. See 20 CPR.
    §§ 404.1520(a)(4), 416.920(a)(4). Under this evaluation, a claimant must first show that
    he is not presently engaged in substantial gainful activity (“step one”). Id at §§
    404.1520(a)(4)(i), 416.920(a)(4)(i). If he is not, the ALJ must determine whether the
    claimant has a “severe” impairment or combination of impairments that limit his ability
    to perform basic work for at least 12 consecutive months (“step two”). See id. at §§
    404.1520(a)(4)(ii). 416.920(a)(4)(ii). Ifthe impairment is severe, the ALJ must
    determine whether it (a) “meets” or (b) “functionally equals” one of the impairments
    listed in 20 CPR. Part 404, Subpart P, Appendix 1 (“step three”). Id. at §§
    404.1520(a)(4)(iii), 416.920(a)(4)(iii). Ifthe impairment does not meet that threshold,
    the claimant must demonstrate that he is nonetheless unable to perform his prior work
    (“step four”). Id. at §§ 404.1520(a)(4)(iv), 416.920(a)(4)(iv). Ifthe AL] is satisfied
    that the claimant is incapable of returning to his prior work, the ALJ must determine
    whether, based on the claimant’s “residual functional capacity,” he can “make an
    adjustment to other work” in the national economy (“step five”). Id. at §§
    404.1520(a)(4)(v), 416.920(a)(4)(v).
    Applying this framework, the ALJ found that plaintiff satisfied the first two steps
    of the evaluation. AR at 21-22. Although the ALJ found that plaintiffwas severely
    impaired, he nonetheless found at the third step of the inquiry that plaintiffs condition
    did not meet or equal any of the enumerated impairments in 20 C.F.R. Part 404, Subpart
    P, Appendix 1. AR at 22-24. Before reaching steps four and five, the ALJ determined
    that, beginning on November 7, 201 1, plaintiff retained the residual functional capacity
    to:
    “perform light work . . . except [that] he should do no climbing
    of ladders/ropes/scaffolds; can perform stooping on an
    occasional basis; limited to work requiring remembering and
    carrying out simple instructions (no complex tasks) with
    occasional contact with co-workers, supervisors[,] and the
    public; and due to concentration/focus problems, the claimant
    may be off—task 5% of the work day.”
    AR at 27. Based on this assessment, the ALJ concluded at step four that plaintiff was
    capable ofperforming his prior work until November 7, 2011, when he first sought
    treatment for his impairments. AR at 33-34. Nonetheless, the ALJ found at step five
    that after November 7, 201 1, although plaintiff could not perform his prior work, he
    could still perform other work in the national economy. AR at 34-36.
    LEGAL STANDARD
    In a disability proceeding, the ALJ “has the power and the duty to investigate
    fully all matters in issue, and to develop the comprehensive record required for a fair
    determination of disability.” Simms v. Sullivan, 
    877 F.2d 1047
    , 1050 (DC. Cir. 1989)
    (quoting Diabo v. Sec’y ofHEW, 627 F.2d 278,281 (DC. Cir. 1980)). The ALJ’S
    ultimate determination is “conclusive” if it correctly applies the governing legal
    standards and is based on substantial evidence in the record. 42 U.S.C. § 405(g).
    Substantial evidence constitutes “such relevant evidence as a reasonable mind might
    accept as adequate to support [a] conclusion,” Smith v. Bowen, 
    826 F.2d 1120
    , 1121
    (DC. Cir. 1987), and demands, as a practical matter, evidence of more than a scintilla,
    but “less than a preponderance," Affum v. United States, 
    566 F.3d 1150
    , 1163 (DC. Cir.
    2009) (citation and internal quotation marks omitted). The District Court’s task on
    appeal is thus to examine the record under the prism of deference, and to determine,
    based on the record as a whole, whether the ALJ articulated a supportable basis for his
    conclusion. See Simms, 877 F.2d at 1050.
    DISCUSSION
    Plaintiff here makes several challenges to the ALJ’s decision. He first claims
    that in determining plaintiff” s residual functional capacity to perform his prior work, the
    ALJ improperly weighed the opinions of his treating physicians and discounted his
    allegations ofpain. Plaintiff next claims that because ofthese errors, the ALJ’S reliance
    on the vocational expert to determine that he could perform work in the national
    economy was misplaced. For the reasons discussed below, I find plaintiff s contentions
    unavailing and uphold the ALJ’s determination.
    I. ALJ’s Residual Functional Capacity Analysis
    Plaintiff first argues that the ALJ erroneously determined he has the residual
    functional capacity (“RFC”) to perform “light work.” Pl.’s Mem. of Law in Supp. Mot.
    J. Reversal (“Pl.’s Mem.”) at 12—22 [Dkt #11—1]. I disagree. Before making a
    determination as to whether a claimant can return to past work, or engage in alternative
    employment, the ALJ must perform an RFC analysis. See 20 C.F.R. §§ 404.1545(a)(1);
    416.945(a)(1); SSR 96—8p, Pol ’y Interpretation Ruling Titles [I andXVI.‘ Assessing
    Residual Functional Capacity in Initial Claims, 
    1996 WL 374184
    , at *2 (S.S.A. July 2,
    1996). RFC is “an administrative assessment of the extent to which an individual’s
    medically determinable impairment(s) . . . may affect his or her capacity to do
    work-related physical and mental activities.” SSR 96—8p, 
    1996 WL 374184
    , at *2.
    RFC is based on numerous factors, including an individual’s medical records, testimony,
    and subjective assertions of pain. In rendering his determination, the ALJ has the
    exclusive duty to evaluate, and weigh, the totality of the evidence. See 20 C.F.R. §§
    404.1527, 416.927. Despite this latitude, it is incumbent on the ALJ to explain “how he
    considered and resolved any material inconsistencies or ambiguities evident in the
    record” and to articulate the reasons for rejecting any evidence “in conflict with the
    ultimate RFC determination.” Butler v. Barnlzart, 
    353 F.3d 992
    , 1000 (DC. Cir. 2004)
    (quoting SSR 96-8p, 
    1996 WL 374184
    , at *7).
    A. Weight of Medical Opinions
    Plaintiff first argues that in assessing his RFC, the ALJ improperly weighed the
    medical opinions of Doctors Kasaci, Walseman, and Ball. P1.’s Mem. at 12-20. Not
    so. Although ALJs generally accord substantial weight to the opinions of treating
