OPINION OF THE COURT
Kissinger appeals from the sentence he received for violating his probation. The magistrate judge had jurisdiction to impose the sentence under 18 U.S.C. § 3401(a). The district court had jurisdiction under 18 U.S.C. § 3742(g). We have jurisdiction over this timely appeal pursuant to 28 U.S.C. § 1291. Because Kissinger has been unconditionally released from custody and probation in the interim, we dismiss this appeal as moot.
I
On July 3, 1999, Kissinger was arrested while protesting the conviction of Mumia Abu-Jamal at the Liberty Bell Pavilion in Independence National Historic Park. Kissinger was convicted under 36 C.F.R. § 2.32(a)(2) for violating a lawful government order “where the control of public movement and activities [was] necessary to maintain order and public safety.” The magistrate judge sentenced Kissinger to a one-year term of probation with a condition that Kissinger not leave New York City without obtaining permission from his probation officer.
During this probationary period, Kissinger requested permission to speak at a political demonstration in Philadelphia. The magistrate judge denied this request, but Kissinger nevertheless traveled to Philadelphia. The magistrate judge sentenced Kissinger to three months imprisonment and one year probation for violating his probation condition. Kissinger contends that the imposition and administration of the probation condition violated his First Amendment rights.
II
Our statutory jurisdiction to consider Kissinger’s appeal is not necessarily lost by his unconditional release from custody.
United States v. Antar,
Kissinger does not attack his underlying conviction. Instead, he challenges the probation condition limiting his ability to travel. While his appeal was pending before this court, Kissinger completed the probationary and incarceration period. The question is whether his appeal is now moot.

Generally, once a litigant is unconditionally released from criminal confinement, the litigant must prove that he or she suffers a continuing injury from the collateral consequences attaching to the challenged act.

the petitioner was convicted of felony stealing and burglary.
Id.
at 3,
Kissinger seeks to distinguish
Spencer
on the ground that
Spencer
involved a parole revocation proceeding, while the present action involves a probation revocation proceeding. Kissinger argues his probation revocation imposed a new sentence because probation revocation proceedings are heard by a judge, while parole revocation proceedings are heard before a parole board. Even assuming (but not deciding) that probation revocation proceedings impose a new sentence, Kissinger’s attempted distinction would not affect our mootness determination. Several courts have applied
Spencer
to the revocation of supervised release.
United States v. Meyers,
Kissinger has simply not shown any distinction between parole and probation that would justify distinguishing
Spencer.
We hold that
Spencer
is not limited to the parole context, but applies with equal force in the probation context.

States v. Ofchinick,
B
In attempting to demonstrate sufficient collateral consequences arising from his probation revocation, Kissinger argues that his allegedly invalid record as a probation violator may enhance his sentences in future crimes. This collateral consequence is insufficient to breathe life into the mooted controversy because the possible effect of an increased sentence depends on Kissinger’s subsequent commission and conviction of a crime.
Spencer,
Kissinger argues that his allegedly invalid record as a probation violator may cost him a bail release. Yet a former probation violation is one factor of many that would guide a judge’s discretion on bail release, 18 U.S.C. § 3142(g);
Probber,
Kissinger also argues that an allegedly invalid probation violation would have the effect of chilling his constitutionally protected speech. While expressing no opinion as to whether this injury is sufficient to meet Article Ill’s injury-in-fact requirement, we conclude that this injury does not present a sufficient collateral consequence. First, the alleged chilling effect is too speculative to afford this court jurisdiction. It is precisely this sort of speculation that
Spencer
deems insufficient to bypass the Article III constraints.

Lastly, Kissinger argues that this case presents a situation that is capable of repetition yet evading review, a narrow exception to the mootness doctrine. Coun

ty of Morris v. Nationalist Movement,
Kissinger has not established that the challenged probation condition is in its duration too short to be fully litigated prior to its expiration. Other challenges to probation conditions have been decided by this court.
United States v. Loy,
Kissinger has also failed to establish a reasonable probability that he will again be arrested, convicted, and placed on probation with the challenged condition. Instead, Kissinger contends only that his political activities increase his chances of arrest, whether or not he has actually committed any offense, “simply because he does not avoid the company of those engaged in rowdy and sometimes unrestrained actions [when] expressing unpopular political views.” Insofar as Kissinger argues that he is of the type who is more likely that the general citizen to commit a crime, this sort of speculation cannot resurrect his moot claim. “Such conjecture as to the likelihood of repetition has no place in the application of this exceptional and narrow grant of judicial power.”
Abdul-Akbar v. Watson,
Even if Kissinger is later arrested, there is no reasonable expectation that he will again be put on probation with the challenged condition and again be denied permission to travel to political demonstrations.
See, e.g., Abdul-Akbar,
Because there is no live case or controversy before us, Kissinger’s appeal must be dismissed.
