    Before: ROGERS, GRIFFITH and PILLARD, Circuit Judges.
    Opinion for the Court filed by Circuit Judge PILLARD.
    PILLARD, Circuit Judge: Ronnie Leroy Howard appeals
    the denial of his petition for a writ of habeas corpus. Howard
    is a federal parolee with an expected parole termination date
    of June 5, 2016.1 He seeks immediate release from parole,
    contending that procedural irregularities relating to parole
    revocations in 1985 and 2004 warrant habeas corpus relief.
    Howard makes three roughly distinct challenges to his
    federal parole.      First, he argues that the U.S. Parole
    Commission (“Commission”), through a “Notice of Action”
    following a 1985 parole revocation hearing, ordered that the
    first five years of an intervening state sentence, from 1982 to
    1987, would run concurrently with his federal sentence, but
    1
    Effective November 1, 1987, the Sentencing Reform Act of
    1984, Pub. L. No. 98-473, § 212(a)(2), 98 Stat. 1837, 1999 (1984),
    “eliminated most forms of parole in favor of supervised release, a
    form of postconfinement monitoring overseen by the sentencing
    court, rather than the Parole Commission.” Johnson v. United
    States, 
    529 U.S. 694
    , 696-97 (2000) (citing Gozlon-Peretz v. United
    States, 
    498 U.S. 395
    , 400-01 (1991)); see 18 U.S.C. § 3583.
    Congress has extended the federal parole system seven times to
    allow the Commission to continue monitoring the handful of
    individuals, like Howard, who were sentenced for offenses
    committed before November 1, 1987, and who remain on federal
    parole. See, e.g., United States Parole Commission Extension Act
    of 2013, Pub. L. No. 113-47, § 2, 127 Stat. 572 (2013) (extending
    parole through 2018). The primary difference between parole and
    supervised release is that the latter is an additional, independent
    term of supervision imposed at sentencing, whereas parole is
    granted to individuals already serving a term of confinement,
    allowing them to complete an existing sentence of incarceration
    outside of prison.
    3
    failed to treat them as concurrent. But for the Commission’s
    failure to run his terms concurrently, as Howard says the
    Commission informed him it would, he would now be free
    from parole. Howard’s claims arising out of that alleged
    surprise reversal fail because they all rest, at bottom, on a
    misreading of the admittedly opaque Notice of Action, which
    directed that the specified five years would run consecutively.
    Second, Howard makes several arguments founded on his
    contention that the Commission did not properly execute, or
    never executed, a 1982 parole violator warrant it lodged
    against him. At the conclusion of the three day evidentiary
    hearing in this case, the magistrate judge found that the
    Commission executed the 1982 warrant on July 21, 1987.
    Howard argues, however, (1) that the magistrate judge’s
    factual finding was clearly erroneous, (2) that the magistrate
    judge abused her discretion and violated his due process
    rights by failing to aid him in calling additional witnesses at
    the evidentiary hearing whose testimony could have helped
    him to prove that the Commission did not execute the warrant
    in 1987, and (3) that he received ineffective assistance of
    counsel because his attorney failed adequately to press his
    warrant execution argument and failed adequately to help him
    to locate and procure his witnesses. All of Howard’s claims
    relating to the execution of his 1982 parole violator warrant
    fail, however, because Howard had no right to have the
    warrant executed, and the Commission had no obligation to
    execute it. It is thus immaterial whether the Commission ever
    executed the 1982 parole violator warrant.
    Finally, Howard contends that the Commission executed
    a separate 1998 parole violator warrant in 2000 or 2002, but
    delayed the associated parole revocation hearing until 2004.
    He argues that that multiyear delay between execution and
    revocation was unreasonable and prejudicial, and therefore
    4
    violated his due process rights. The magistrate judge found,
    however, that the Commission executed the 1998 parole
    violator warrant in 2004. Howard’s petition raises no grounds
    warranting reversal of that determination, and Howard does
    not argue that the minor delay between his 2004 warrant
    execution and 2004 revocation hearing violated his right to
    due process.
    Because none of Howard’s claims merits habeas relief,
    we affirm the judgment of the district court denying his
    petition.
    I.
    Howard is a serial recidivist who has served time in
    prison for various federal and state crimes and is currently on
    federal parole, with an expected parole termination date in
    2016. He is a 67-year-old Vietnam veteran who has struggled
    for much of his life with addictions to cocaine and other
    drugs. He has kidney disease, which, at the time of his
    petition, did not yet require dialysis treatment.
    The concurrent 20- and 25-year federal sentences for
    which Howard remains on parole were for two bank robberies
    Howard committed in 1970. Howard was imprisoned at the
    Lorton Reformatory Adult Services Complex, a federal
    penitentiary in Lorton, Virginia, but escaped in the early
    1970s by climbing a fence, adding 15 months to his sentence.
    Several years later, Howard again gained release on parole,
    but a further series of crimes, state sentences of
    imprisonment, and corresponding breaks in and violations of
    his federal parole had, by 2011, pushed Howard’s parole
    termination date from 1996 to 2022. After Howard filed this
    case, the Commission reduced Howard’s parole term, giving
    him an anticipated release date in 2016.
    5
    Howard traveled a circuitous path to 20 extra years of
    federal penal supervision. After Howard served nine years in
    federal prison, the government paroled him in 1979. While he
    was on parole, Howard committed serious crimes in Virginia,
    including armed robbery. In 1982, the Commission issued a
    “parole violator warrant” for Howard for those and other
    parole violations. A parole violator warrant is a warrant
    issued by the Commission pursuant to its authority to “retake”
    parolees who have violated their federal parole and return
    them to federal prison—or at least formally to return them to
    the custody of the Attorney General. 18 U.S.C. § 4213(a)(2).
    The Commission did not immediately execute the warrant and
    return Howard to federal prison, however, because by then he
    was in state prison pursuant to his 1982 conviction and 18-
    year sentence for armed robbery in violation of Virginia law.
    In 1985, while Howard was incarcerated in Virginia, the
    Commission conducted a “dispositional revocation hearing”
    to determine what effect Howard’s parole violations would
    have on completion of his federal sentence. At a dispositional
    revocation hearing, or parole revocation hearing, the
    Commission may revoke parole and return an individual to
    federal prison, 
    id. § 4214(d),
    and, where a parolee is
    convicted of a crime “punishable by a term of imprisonment”
    during his release on parole, the Commission may also
    determine that his time already spent on parole does not count
    toward his underlying sentence, 
    id. § 4210(b)(2);
    see also 28
    C.F.R. § 2.52(c)(2). The Commission is also permitted to toll
    a parolee’s federal sentence while he serves a term of
    imprisonment for another offense. 18 U.S.C. § 4210(b)(2)
    (“[T]he Commission shall determine . . . whether all or any
    part of the unexpired term [of the original sentence] being
    served at the time of parole shall run concurrently or
    consecutively with the sentence imposed for the new
    6
    offense . . . .”); see also Santa v. Tippy, 
    14 F.3d 157
    , 158-59
    (2d Cir. 1994).
    At Howard’s revocation hearing, the Commission
    decided to revoke his parole and not to credit the six years he
    had been out on parole toward his federal sentence. The
    Commission further determined that Howard, who was still
    incarcerated in Virginia, would not resume earning credit
    toward his federal sentence until 1987. As the magistrate
    judge explained, the decision of the Commission “effectively
    tolled his federal sentence by 60 months.” App. at 689.
    The Commission informed Howard of its findings
    through a Notice of Action, the disputed meaning and legal
    effect of which are central to this appeal. A Notice of Action
    is, inter alia, a document that the Commission must provide
    to a parolee following a parole revocation proceeding. See,
    e.g., 18 U.S.C. § 4214(e); 28 C.F.R. § 2.13(c). As relevant
    here, following a parole revocation hearing, the Commission
    must “furnish the parolee with a written notice of its
    determination.” 18 U.S.C. § 4214(e). Howard’s Notice of
    Action following his 1985 parole revocation hearing
    attempted to communicate to him that the Commission had
    decided to revoke his parole and deny him credit for the six
    years he had spent on parole since his release from federal
    prison in 1979 (including the time he had already served in
    prison in Virginia). The Notice of Action also sought to
    inform him that time would again start counting towards his
    federal sentence upon his release from Virginia custody into
    federal custody or after he spent an additional five years in
    state prison. No part of his first five years in Virginia
    custody, were he to serve that long, would count toward his
    federal sentence.
    7
    In 1987, with Howard still imprisoned in Virginia, his
    federal parole began to run again. The effect of the
    Commission’s decision was to move back eight years, from
    1996 to 2004, the date of expiration of Howard’s federal
    sentence. Because of his various parole revocations and
    withdrawals of parole credit, Howard was back at square one
    with respect to his remaining 17-year federal sentence.2 It
    was as if the sentence had been reset to 1979, when he was
    released on parole, and the eight years between then and 1987
    never happened.
    In 1992, after Howard served nine years in state prison,
    Virginia paroled him, and he remained on parole, not
    reincarcerated, pursuant to his federal sentence. In the
    ensuing years Howard again violated his federal parole by
    committing cocaine-related crimes and other offenses in
    violation of Virginia law. In 1998, the Commission issued a
    new parole violator warrant for Howard, charging him with
    parole violations dating back to 1992, including the cocaine-
    related crimes. At the urging of Howard’s federal probation
    officer, however, in order to afford Howard an opportunity to
    participate in a non-prison-based drug treatment program
    through the Veterans Administration, the Commission
    ordered the 1998 warrant be held in abeyance and did not
    immediately arrest Howard and return him to prison. In 2000,
    the Commission—apparently by mistake—issued a second
    warrant listing the same charges plus two additional technical
    parole violations for Howard’s failure to report a change of
    residence and failure to submit required reports. The
    Commission withdrew that second warrant in 2001.
    Meanwhile, the March 1998 warrant remained in abeyance.
    2
    Howard had 17 years remaining on his 26-year term, having
    served nine years in federal prison from 1970 to 1979 that, unlike
    years served as parole, could not be revoked.
    8
    In 2002, Virginia arrested, tried, and convicted Howard
    of the possession of cocaine with intent to distribute,
    sentencing him to two years imprisonment.                Shortly
    thereafter, the Commission supplemented its 1998 parole
    violator warrant to include the 2002 arrest and ordered that it
    be reactivated. The Commission ordered that Howard be
    arrested or, if he was already in Virginia custody, that the
    warrant be lodged as a “detainer” at the institution where he
    was being held. A warrant lodged or placed as a detainer
    instructs another jurisdiction that is holding an individual not
    to release him until the warrant-issuing jurisdiction has had an
    opportunity to take him into custody. Moody v. Daggett, 
    429 U.S. 78
    , 80 n.2 (1976).
    Upon Howard’s release from Virginia custody in 2004,
    federal officials executed the 1998 warrant and took Howard
    into federal custody, incarcerating him at the Albemarle-
    Charlottesville Joint Security Complex. The Commission
    conducted a parole revocation hearing 127 days later and
    found that Howard had violated the conditions of his parole.
    As it had in 1987, the Commission reset Howard’s parole
    clock, revoking the approximately 17 additional years he had
    spent on federal parole since 1987, and assigning him a new
    release date in 2021. Subsequent parole violations added to
    his sentence, moving his release date to 2022.
    In 2006, Howard, who was no longer incarcerated, began
    to seek relief in federal court from his continuing federal
    parole. The district court in 2010 construed one of his
    complaints as a petition for habeas corpus, directed the
    Commission to show cause why the writ should not issue, and
    referred the petition to a magistrate judge. Howard’s petition
    argued, among other things, that between 1982 and 1987 his
    federal and state sentences should have run concurrently, and
    9
    that his 2004 parole revocation hearing was unreasonably and
    prejudicially delayed.
    In light of that petition, the Commission reconsidered
    Howard’s parole term.           The Commission found that
    irregularities associated with the execution of his 1998 parole
    violator warrant, along with his illness and advanced age,
    justified a reduction in the term. The Commission elected to
    credit him with approximately five years toward his parole
    termination date, revising it from 2022 to 2016.
    The magistrate judge held a three-day evidentiary hearing
    in 2011 and issued a Report and Recommendation denying
    Howard’s habeas petition. The district court adopted the
    Report and Recommendation. This appeal followed.
    II.
    In reviewing a district court’s decision to grant or deny a
    habeas corpus petition, we review its factual findings for clear
    error, see Amadeo v. Zant, 
    486 U.S. 214
    , 223 (1988), and its
    legal conclusions de novo, see Barhoumi v. Obama, 
    609 F.3d 416
    , 423 (D.C. Cir. 2010).
    A.
    The Commission did not improperly deny Howard credit
    towards his federal sentence from 1982 to 1987 when he was
    a prisoner in Virginia. Howard pins his argument on
    language in the Notice of Action the Commission issued
    following his 1985 parole revocation hearing. Appellant Br.
    at 15, 21-30. The paragraph—under a heading that states that
    at the conclusion of Howard’s hearing “the following action
    was ordered” (hereinafter the “order”)—explains:
    10
    Revoke parole; none of the time spent on parole shall
    be credited. The unexpired portion of your federal
    sentence shall commence upon your release from state
    custody or upon federal reparole to your state
    sentence, whichever comes first. Continue to a
    presumptive parole from the violator term after the
    service of sixty months (July 1, 1987).3
    3
    The language of the Notice of Action is almost certainly adapted
    directly from the Commission’s Rules and Procedures Manual. The
    1984 Manual instructs that Commission orders revoking time and
    retroactively denying credit for street time should read:
    Revoke parole; none of the time spent on parole shall be
    credited. The unexpired portion of your federal sentence
    shall commence upon your release from state custody or
    upon federal reparole to your state sentence, whichever
    comes first;
    . . . (Continue for a presumptive) parole from the violator
    term (date).
    U.S. Parole Comm’n, U.S. Dep’t of Justice, Rules and Procedures
    Manual 168 (1984) (“1984 Manual”) (parentheses in original).
    Very similar language appears in the current Rules and Procedures
    Manual. See U.S. Parole Comm’n, U.S. Dep’t of Justice, Rules and
    Procedures Manual 282 (2010) (“2010 Manual”). Because the
    Commission’s guidelines instruct the Commission what to say in its
    Notices of Action, these confusing and ungrammatical phrases have
    been repeated verbatim in innumerable Notices of Action
    nationwide for decades. This lack of clarity is troubling because a
    Notice of Action is the document meant to communicate to a
    parolee how his sentence has been recalculated and thus how much
    more time he must spend in custody—whether in prison or on
    parole. The Notice of Action should inform the parolee’s critical
    decisions about, for instance, whether to take an appeal. The
    government should place a high priority on writing such documents
    11
    All parties agree that the phrase “violator term” refers to
    Howard’s underlying federal sentences for which he was
    scheduled to serve 26 years. The parties also agree that the
    order revoked Howard’s parole and denied him credit for his
    three years of street time—time spent free on parole—
    between 1979 and 1982.
    The meaning of the remainder of the order is contested.
    Howard argues that it “can only be interpreted to impose a
    concurrent term from 1982-1987,” i.e. as announcing that his
    state sentence and federal parole ran concurrently rather than
    consecutively. Appellant Br. at 21 (emphasis added). The
    government disagrees, contending that the Notice of Action
    “makes clear it will not give [Howard] credit toward his
    original federal sentence for all of the time spent in state
    prison, and therefore, the sentences were consecutive, not
    concurrent.” Appellee Br. at 36-37.
    Howard contends that the district court must be reversed
    for legal error because he is entitled to release based on his
    interpretation of the Notice of Action. But the district court’s
    erroneous interpretation of the Notice of Action matters only
    if Howard has some underlying right to relief that turns on
    what it says. Howard’s briefing focuses on the Notice of
    Action’s convoluted wording, apparently to support a claim
    that it violated his rights by failing to give him adequate
    notice that his terms ran consecutively. If Howard indeed
    received no reasonable notice of the Commission’s decision
    and was prejudiced thereby, he might have a due process
    claim. See Morrissey v. Brewer, 
    408 U.S. 471
    , 489 (1972).
    Whatever the precise nature of his claim, however, Howard
    in plain English.         One would reasonably expect that the
    Commission could draft more plainly the language that it intends be
    used to inform uncounseled laypeople in federal custody of matters
    vitally affecting their freedom.
    12
    has advanced no ground warranting habeas corpus relief. The
    Notice of Action, despite its painful legalese, ordered his
    sentences to run consecutively.        Together with his
    participation in his 1985 parole revocation hearing and his
    receipt in 1987 of other Commission documents reflecting the
    consecutive sentence, the Notice of Action adequately
    informed Howard of the Commission’s decision to run his
    terms consecutively.
    The parties spar over the appropriate level of deference
    the Court should afford to the Commission’s interpretation of
    the Notice of Action. Howard argues for no deference; the
    Government for maximal deference. Appellant Br. at 16-20;
    Appellee Br. at 29-32; see also Auer v. Robbins, 
    519 U.S. 452
    , 461 (1997). A decision regarding the precise degree of
    scrutiny is unnecessary, because, even when we review it
    without deference, we find that the Commission’s Notice of
    Action makes sufficiently clear that Howard’s Virginia and
    federal sentences would run consecutively.
    The second sentence of the order sets the date on which
    Howard’s federal sentence would again start to run as one of
    two dates, “whichever [came] first”: either (a) his “release
    from state custody,” i.e., when Virginia released him from
    prison; or (b) “federal reparole.” App. at 83. The date of
    Howard’s “federal reparole” is specified by the final sentence,
    which provides that Howard would “[c]ontinue to a
    presumptive parole from the violator term”—that is, his 26-
    year federal sentence—“after the service of sixty months (July
    1, 1987).” 
    Id. In other
    words, even though Howard’s federal
    and state sentences were not generally concurrent, the Notice
    of Action provided that Howard would become presumptively
    entitled to concurrent federal reparole after 60 months,
    running the federal clock again even if he were then still in
    Virginia custody. Howard remained in Virginia state prison
    13
    until 1992—after July 1, 1987—and therefore the second
    alternative “[came] first” and Howard was “reparoled to [his]
    state sentence,” so the state sentence started counting as
    service of federal parole as of July 1987.
    Howard argues that our reading of the Notice of Action is
    too generous, and that the key words, “from the violator
    term,” cannot bear the meaning the Commission and the court
    ascribe to them. In Howard’s view, the Commission could
    not “reparole” him “from” a violator term unless he was in
    fact serving time toward that violator term when he was
    reparoled “from” it. Thus, the sentence that reads “[c]ontinue
    to a presumptive parole from the violator term after the
    service of sixty months (July 1, 1987)” implies, in Howard’s
    estimation, that the notice of action imposes a concurrent term
    from 1982 to 1987. Appellant Br. at 21-22. Howard argues
    that the words “from the violator term” are used elsewhere in
    the Notice of Action to mean what he says they do. For
    example, in the “Reasons/Conditions” section the
    Commission explains: “If you are still in state custody as of
    the above date [July 1, 1987], you will have a presumptive
    parole from the violator term to your state sentence on the
    above date.” App. at 83. Again, according to Howard, the
    government could not have paroled him “from” his violator
    term unless he was already serving it concurrently with his
    state sentence. Thus Howard argues that the Notice of Action
    states that his federal sentence was to run concurrently with
    his Virginia sentence. Howard further contends that the
    default presumption should be that federal and state sentences
    run concurrently, unless the Commission speaks clearly to the
    contrary. Because, in his view, “nowhere did the Commission
    explicitly impose a consecutive sentence” in his case, his time
    spent in Virginia must be credited toward his federal sentence.
    14
    We disagree. The language of the “order” section of the
    Notice of Action is admittedly confusing. It does not
    explicitly say that Howard’s state and federal terms are to run
    consecutively. But once we parse it carefully and in context,
    we understand the Notice of Action to state the Commission’s
    determination that Howard’s terms were to run consecutively.
    To read the Notice of Action as Howard suggests ignores the
    fair import of its words. The phrase “parole from the violator
    term” is not meant to indicate that he would have been
    serving the violator term immediately before the
    recommencement of parole; instead, “parole from the violator
    term” simply identifies the criminal sentence from which, for
    the Commission’s purposes, he would be paroled—i.e. that
    the parole pertains to the federal sentence of incarceration, or
    “violator term.” According to the Notice of Action, Howard
    was to be returned to parole “from,” as in originating in or
    relating to, his federal violator term.
    This understanding is reinforced by the remainder of the
    Notice of Action’s text. On the same page as the disputed
    “order”       paragraph,     the    Notice      of    Action’s
    “Reasons/Conditions” section explains that, if Howard were
    still in state custody as of July 1, 1987, he would “have a
    presumptive parole from the violator term to [his] state
    sentence” on July 1, 1987. App. at 83. The Notice of Action
    also stated that, in circumstances like Howard’s—given the
    severity of his parole violations—the “[r]eparole guidelines
    indicate a customary range of 48-60 months to be served
    before re-release” and that “[a]fter review of all relevant
    factors and information presented, a decision outside the
    guidelines . . . is not found warranted.”

    of the Notice of Action’s practical consequences

    whole.

    Howard also received a parole certificate in August 1987,
    a month after his July 1987 reparole date. The parole
    certificate stated that Howard’s parole would extend through
    October 1, 2004.         The date on the parole certificate
    presupposed that Howard’s state and federal sentences ran
    consecutively. Howard received that document but did not
    object to it for decades, despite the fact that, according to his
    current position, it misstated his parole termination date by
    several years. See App. at 677.
    Howard insists that, when a Notice is ambiguous on the
    point, the presumption should be that sentences run
    concurrently. Yet, when Howard had his parole revocation
    hearing in 1985, the Commission’s public guidelines and
    regulations, as well as decisions of the Supreme Court and
    numerous Federal Courts of Appeals, were clear and
    unanimous that the Commission’s policy was to run federal
    and state sentences consecutively unless otherwise specified.
    See, e.g., 
    Moody, 429 U.S. at 85
    ; Still v. U.S. Marshal, 
    780 F.2d 848
    , 855 (10th Cir. 1985) (Logan, J., dissenting); U.S.
    Parole Comm’n, U.S. Dep’t of Justice, Rules and Procedures
    Manual 119 (1984) (“1984 Manual”). The Commission’s
    policy has never wavered, and was its policy at the time of
    Howard’s revocation hearing and Notice of Action. 28 C.F.R.
    § 2.47(d)(2) (1984).4 Howard insists that he relied on the
    advice of his lawyer in concluding that his terms would run
    concurrently. Evid. Hearing Tr. May 11, 2011 a.m., at 15:12-
    18. But even if Howard was confused, his confusion was not
    objectively reasonable in the circumstances of this case. Even
    accepting that the Notice of Action is somewhat unclear
    standing alone, there can be little doubt as to its meaning
    when it is read together with the other relevant facts and
    4
    The policy was renumbered from § 2.47(c) to § 2.47(d)(2)
    between 1976 and 1986, and now is codified at § 2.47(e)(2).
    16
    against the background of generally available and directly
    relevant legal sources.
    In sum, the actions of the Commission at the time
    Howard received his Notice of Action, along with the context
    and circumstances in which the Commission issued it,
    bolstered the Commission’s message that it never intended his
    federal and state sentences to run concurrently. Every
    document, memorandum, transcript, certificate, and notice of
    any kind issued by the Commission regarding Howard’s
    parole—save, arguably, Howard’s Notice of Action—made
    clear that Howard’s sentences ran consecutively. Howard
    stakes his case on an admittedly awkward phrase in his Notice
    of Action. Yet the Commission’s reading of the order’s text
    and its further explication of its determination in the
    remainder of the Notice combine to defeat his claim that the
    Commission ordered his sentences run concurrently.
    B.
    Howard raises several arguments centered on his
    contention that the Commission either did not execute his
    1982 parole violator warrant in 1987, or did not execute it
    properly. The magistrate judge concluded that “the 1982
    warrant was executed, and it was executed on July 21, 1987.”
    App. at 687. Howard claims that decision was erroneous.
    With respect to the propriety of the warrant’s execution,
    Howard argues that the Commission never executed the 1982
    warrant because he never received notice of its execution, and
    because federal agents never took him into physical
    custody—both of which, he argues, are necessary for a parole
    violator warrant to be executed.
    Howard also raises several procedural challenges to his
    habeas corpus hearing before the magistrate judge, all of
    which arise out of his dissatisfaction with the judge’s and his
    17
    own attorney’s treatment of his contentions regarding
    execution of his 1982 parole violator warrant. He claims that
    the magistrate judge abused her discretion and denied him due
    process of law because she did not allow him to call several
    witnesses he argues would have been able to help him to
    establish that the Commission never executed the 1982
    warrant. Howard further asserts that he received ineffective
    assistance of counsel at his evidentiary hearing because his
    attorney did not do enough to help him to procure those
    witnesses or to press his argument that the Commission did
    not execute the 1982 warrant.
    Those arguments fail together because they rest on the
    faulty premise that it is legally material whether Howard’s
    1982 parole violator warrant was ever executed. Neither the
    Due Process Clause nor any statute or regulation obligated the
    Commission to execute the 1982 warrant, see 
    Moody, 429 U.S. at 87
    ; Donn v. Baer, 
    828 F.2d 487
    , 489 (8th Cir. 1987),
    and the Commission’s authorizing statute did not require it to
    execute the warrant in order to exert jurisdiction over
    Howard, see 18 U.S.C. §§ 4213(a), 4214(d); see also Heath v.
    U.S. Parole Comm’n, 
    788 F.2d 85
    , 91 (2d Cir. 1986).
    Howard has not identified nor can we discern a violation of
    any right Howard might have that would turn on the execution
    of his 1982 parole violator warrant.
    To understand why the nonexecution of the 1982 warrant
    was legally innocuous, it may be helpful to review the
    interplay between parole violator warrants and parole
    revocations.    Such warrants are used by the Parole
    Commission to take parolees back into federal custody for
    alleged parole violations. When such a warrant is executed,
    federal law requires that the parolee receive a prompt parole
    revocation hearing to determine what consequences will flow
    from the parolee’s alleged violation. See Sutherland v.
    18
    McCall, 
    709 F.2d 730
    , 732 (D.C. Cir. 1983). But the inverse
    is not the case. Even if there is a revocation hearing, there is
    no similar requirement that the outstanding parole violator
    warrant to which it relates ever be executed. As the Supreme
    Court explained in Moody, “execution of the [parole violator]
    warrant and custody under that warrant” are the “operative
    event[s] triggering any loss of liberty attendant upon parole
    
    revocation.” 429 U.S. at 87
    . Thus, “the mere issuance of a
    parole violator warrant works no present deprivation of
    protected liberty sufficient to invoke due process protection.”
    
    Id. at 85.
    The “Commission . . . has no constitutional duty to
    provide [a parolee] an adversary parole hearing until he is
    taken into custody as a parole violator by execution of the
    warrant.” 
    Id. at 89.
    Howard was already in custody in
    Virginia.
    This asymmetry explains why Howard received a parole
    revocation hearing in this case even though the Commission
    may never have executed the parole violator warrant to which
    it was ostensibly linked.       Moody established that the
    Commission may delay executing a parole violator warrant—
    and therefore holding a parole revocation hearing—until the
    “expiration of [a] parolee’s intervening sentence.” 
    Id. at 89.
    The dissenters in Moody were critical of the Court’s
    conclusion that the Commission had “no obligation to go
    forward with the revocation hearing until after the parolee has
    completed the service of his sentence for [a] second offense”
    and could therefore “wait as long as 10 or 20 years” before
    holding a 
    hearing. 429 U.S. at 91
    (Stevens, J., dissenting).
    Perhaps mindful of that perceived unfairness, the Commission
    has made it a practice to act earlier to hold revocation
    hearings on parole violations that result in an independent
    term of imprisonment. See Paroling, Recommitting, and
    Supervising Federal Prisoners, 46 Fed. Reg. 35,635, 35,635
    (July 10, 1981) (recognizing 1980 change in policy to
    19
    “provid[e] revocation hearing more promptly for persons
    incarcerated with new sentences”). At the time of Howard’s
    incarceration, the Commission’s regulations advised that such
    hearings were to be held within 24 months of an individual’s
    incarceration, and that the underlying warrant was to be let to
    “stand as a detainer.” 
    Id. at 35,637
    (announcing extensions to,
    inter alia, 28 C.F.R. § 2.47(b)(1)(i)). But once a pre-
    execution parole revocation hearing has been held, as it was
    in Howard’s case in 1985, there is no requirement that the
    underlying parole violator warrant be executed if it is not
    needed for the purpose of arrest or detainer. For this reason,
    the policy of the Commission at the time of Howard’s
    incarceration in Virginia in the 1980s, as today, is to withdraw
    parole violator warrants that are no longer needed, not to
    execute them. See 1984 Manual at 123; accord U.S. Parole
    Comm’n, U.S. Dep’t of Justice, Rules and Procedures Manual
    132 (2010) (“2010 Manual”).
    In Howard’s case, the Commission’s 1985 parole
    revocation hearing was of this pre-execution type. It
    pertained to the same alleged parole violations that led to the
    issuance of his 1982 parole violator warrant. Once the
    Commission held the hearing, whether the Commission
    executed the parole violator warrant or not no longer
    mattered, so long as its actions conformed to its decision in
    Howard’s parole revocation hearing. The Commission let
    Howard’s parole violator warrant stand as a detainer between
    1982 and 1987 because the Commission concluded at his
    parole revocation hearing that Howard should serve at least
    five years in prison for his parole violations—and if Virginia
    released him sooner, for whatever reason, the Commission
    wanted to ensure it would be notified so it could incarcerate
    him at a federal institution to complete the remainder of his
    60 months in prison. But once 60 months passed, the
    Commission no longer sought to return Howard to federal
    20
    prison, so execution of the warrant was unnecessary. As of
    July 21, 1987, in the eyes of the Commission, Howard was
    once again on federal parole whether his warrant was
    executed or not.
    The premise of the balance of Howard’s claims relating
    to the 1982 parole violator warrant is that, if he could prove
    the warrant was not executed or executed improperly, he
    would be entitled to habeas corpus relief; the error of that
    premise is fatal to the related claims. The magistrate judge
    permissibly exercised her lawful discretion in determining
    that Howard’s proffered witnesses were irrelevant because
    their testimony was directed at an extraneous issue. Howard’s
    counsel likewise did not render ineffective assistance.
    Whether Howard’s attorney had succeeded in locating the
    witnesses or pressing Howard’s warrant-execution
    contentions more forcefully, it would not have supported his
    habeas petition. See Strickland v. Washington, 
    466 U.S. 668
    ,
    691 (1984) (“An error by counsel, even if professionally
    unreasonable, does not warrant setting aside the judgment of a
    criminal proceeding if the error had no effect on the
    judgment.”).
    C.
    The Commission did not prejudicially delay Howard’s
    2004 parole revocation hearing. Federal law requires that a
    revocation hearing be held 90 days after execution of a parole
    violator warrant. 18 U.S.C. § 4214(c). The Commission’s
    failure to meet the statutory deadline, however, is not grounds
    for habeas corpus relief unless the delay is so prejudicial to
    the parolee that it violates his due process rights. 
    Sutherland, 709 F.2d at 732
    ; see 
    Morrissey, 408 U.S. at 488-89
    . In this
    Circuit, relief for such a due process violation is granted only
    “where a petitioner establishes that the Commission’s delay in
    21
    holding a revocation hearing was both unreasonable and
    prejudicial.” 
    Sutherland, 709 F.2d at 732
    .
    Howard argues that the Commission delayed his 2004
    parole revocation hearing by several years because it executed
    his 1998 parole violator warrant (or “an invalid duplicate”) in
    either 2000 or 2002. In Howard’s view, any such execution
    started the parole-revocation hearing clock. Howard argues
    that the revocation hearing was thus unlawfully delayed by
    two to four years, to his material prejudice. Had his
    revocation hearing been promptly convened, Howard argues,
    he would have had the opportunity to call additional witnesses
    and introduce more mitigating evidence at that hearing, and
    therefore the Commission would have been far less likely
    retroactively to revoke all of his credit for time spent on
    parole between 1987 and 2004.
    The magistrate judge found that the Commission
    executed his 1998 parole revocation warrant in 2004, and that
    it held his parole revocation hearing 127 days later—37 days
    beyond the statutory deadline. In particular, the magistrate
    judge determined that the Commission issued a parole
    violator warrant in 1998, and then held it in abeyance so that
    Howard could participate in a non-prison-based drug
    treatment program. App. at 668. The Commission issued a
    similar, but not identical, parole violator warrant in 2000 that
    it withdrew in 2001 as mistaken and duplicative. 
    Id. at 668-
    69. In 2002, the Commission supplemented the 1998 warrant
    to reflect crimes Howard committed in 2001 and 2002 and
    then lodged the warrant as a detainer. 
    Id. at 669-70.
    The
    Commission executed the 1998 warrant in 2004. 
    Id. at 670.
    In support of his contention that the Commission
    executed his 1998 warrant in 2000 or 2002, such that his 2004
    revocation hearing was unreasonably delayed by several
    22
    years, Howard claims that the magistrate judge’s Report and
    Recommendation failed affirmatively to reject his proffered
    evidence of multiple executions of the same warrant, and
    thereby left those factual questions open and unresolved. But
    the magistrate judge heard and considered Howard’s
    arguments and evidence on that issue. Her opinion quotes,
    summarizes, and presents Howard’s testimony explaining his
    contention that the Commission executed his 1998 parole
    violator warrant in either 2000 or 2002. App. at 675
    (“Petitioner testified that in February or March, 2001, he
    ‘[was] released on bond . . . for the local Virginia
    charge[] . . . , [and] from the Federal parole warrant[.]’”
    (alterations in original)); 
    id. at 676
    (“Petitioner testified that
    he was arrested in October, 2002 in Arlington County ‘for a
    Federal parole violator warrant[,]’ and that the United States
    Marshals took him to the jail in Alexandria, then returned him
    to Arlington County.” (alterations in original)); see also 
    id. at 676
    -78 (describing government’s cross-examination focused
    on showing that neither warrant execution happened). The
    magistrate judge did not fail to address Howard’s evidence,
    but considered it and did not credit it.5
    Howard cannot relitigate the magistrate judge’s factual
    conclusions regarding his warrant issuances and executions
    unless he can show clear error. On questions regarding
    “specific factual determinations about what happened” and
    5
    The magistrate judge devoted several paragraphs of the Report
    and Recommendation to explaining why the Commission’s delay in
    executing the 1998 warrant until 2004 did not prejudice Howard.
    App. at 689-91. He does not appeal on that ground. That discussion
    is relevant here, however, because its factual premise is that the
    Commission executed the 1998 warrant in 2004. In failing to find
    that an earlier warrant execution occurred, the magistrate judge’s
    opinion rejected Howard’s arguments that the Commission
    executed the 1998 warrant in either 2000 or 2002.
    23
    judgments about “whether evidence is sufficiently reliable to
    credit,” we may reverse the judgment below only if it is
    clearly erroneous. Obaydullah v. Obama, 
    688 F.3d 784
    , 792
    (D.C. Cir. 2012) (internal quotation marks omitted). Howard
    identifies evidence pointing both ways on the question
    whether the Commission executed the 1998 warrant in 2000
    or 2002, see, e.g., Appellant Br. at 40-46, but his analysis of
    the record does not leave this Court with a “definite and firm
    conviction that a mistake has been committed,” United States
    v. U.S. Gypsum Co., 
    333 U.S. 364
    , 395 (1948).
    Howard’s habeas claim turns on establishing that the
    Commission’s delay of his parole revocation hearing was both
    unreasonable and prejudicial. He asserted a lengthy delay of
    two to four years and his only claim of prejudice relates to
    that longer period. The magistrate judge’s finding that the
    Commission executed the warrant in 2004 eliminates
    Howard’s claim that the Commission’s delay prejudiced him.
    The only delay at issue on these facts is that his hearing was
    not held until 127 days after his warrant execution—37 days
    beyond the 90-day statutory deadline. Howard does not
    contend that that delay during 2004 was unreasonable or
    prejudicial; indeed, he disclaims any such prejudice.
    Appellant Reply Br. at 15.
    Because the Commission validly executed Howard’s
    warrant in 2004, and he has not attempted to show that the
    delay thereafter in holding his parole revocation hearing was
    unreasonable or prejudicial, we hold that he cannot obtain
    habeas relief on that ground.

    For the foregoing reasons, the decision of the district
