Donald Trump's former campaign chairman, Paul Manafort, will plead guilty on Friday in his second criminal trial, according to NBC News.

Court filings show that Manafort has agreed to plead guilty in special counsel Robert Mueller's probe.

Manafort was facing seven counts of foreign lobbying violations and witness tampering in a trial set to begin later this month.

"Manafort agreed to plead to conspiracy against the U.S. and conspiracy to obstruct justice by tampering with witnesses. He also agreed to forfeit some properties," Bloomberg News reported.

The plea deal reportedly includes a 10-year cap on his prison sentence.

The former Trump aide is scheduled to appear at a hearing for the trial at 11:00 a.m. on Friday.

"I feel very badly for Paul Manafort," Trump told reporters after a federal jury found Manafort guilty on eight counts of federal tax and banking crimes in August.
