A federal judge on Friday scheduled a Feb. 8 sentencing date for Paul Manafort, President Donald Trump's former campaign chairman, who was convicted on eight counts of tax and bank fraud.

Manafort showed up to the Alexandria, Va. courthouse for the hearing reportedly clad in a prison jumpsuit and sitting in a wheelchair. He appeared to be missing his right shoe when he was wheeled into the courtroom, NBC News reported.

His attorney, Kevin Downing, said in court that Manafort is suffering "significant issues" with his health "that have to do with his confinement," The Washington Post reported. Downing did not elaborate on Manafort's apparent health problems, but Judge T.S. Ellis agreed to hasten the preparation of Manafort's pre-sentencing report anyway.

Manafort was sent to jail on June 15 by U.S. District Court Judge Amy Berman Jackson pending his multiple trials in Virginia and Washington, D.C., after prosecutors accused him of tampering with potential witnesses.

His lawyers had complained that Manafort was "locked in his cell for at least 23 hours per day" in solitary confinement as they appealed Jackson's decision.

But prosecutors pushed back, detailing a recorded phone call in which Manafort said the jail staff was treating him like a VIP. He was subsequently transferred to the Alexandria Detention Center.
