Former Trump campaign manager Paul Manafort arrives at the E. Barrett Prettyman U.S. Courthouse for a hearing on June 15, 2018 in Washington, DC.

A federal judge Monday canceled former Trump campaign chief Paul Manafort's sentencing in his Virginia case, which was scheduled for Feb. 8, according to a filing.

U.S. District Judge T.S. Ellis wrote that Manafort's "current dispute" in a separate federal case in Washington, D.C., makes it "prudent and appropriate to delay sentencing in this case."

Special counsel Robert Mueller's team had previously aimed to delay Manafort's sentencing in Virginia until he was finished cooperating with Mueller's probe of Russian election meddling and possible collusion with the Trump campaign.

But Ellis rejected the prospect of doing so as "highly unusual."

A spokesman for Mueller declined CNBC's request for comment on Ellis' court filing.
