Okla. Stat. tit. 21, § 21-61.3: Parole - Revocation - Relinquishment of custody

When a defendant is on parole from a sentence rendered by an

Oklahoma state court and is also under sentence from a federal court

or another state's court, the Governor may revoke the defendant's

parole and direct that custody of the defendant be relinquished to

the federal or another state's authorities and that such parole

revocation may run concurrently with the federal or another state's

sentence which has been imposed. The Governor may also order that a

parole revocation run concurrently with any other sentence rendered

by an Oklahoma state court.
