President Trump’s former campaign manager Paul Manafort will be moved from a federal lockup in Pennsylvania to Rikers Island later this week, a report said Monday.

Manhattan District Attorney Cy Vance Jr.’s office requested the transfer after a New York grand jury charged Manafort with a number of crimes, including residential mortgage fraud and falsifying business records, Fox News reported, citing a source close to Manafort.

The transfer could come as soon as Thursday, and Manafort will be held in solitary confinement for his own safety, according to the report.

Manafort was convicted in August of several federal counts of tax and bank fraud related to his work for Ukrainian nationals. He was indicted on the state charges in New York in March.

His federal conviction was the first successful prosecution brought by special counsel Robert Mueller’s office during his investigation into Russian interference in the 2016 presidential election.

Vance’s office did not immediately respond to a request for comment Monday night.
