Paul Manafort, the onetime chairman of Donald Trump’s presidential campaign, agreed to cooperate with prosecutors Friday as part of a deal in which he pleaded guilty to reduced charges from Special Counsel Robert Mueller III’s office, heading off a second trial less than a month after a Virginia jury found him guilty of tax and bank fraud.

The plea deal, read aloud in a Washington, D.C., federal courtroom by Judge Amy Berman Jackson, will require Manafort to participate in interviews, provide documents in his control, testify in grand jury proceedings and agree to delays for his sentencing. Jackson noted that Manafort also agreed to waive the right to have his lawyers present during meetings with prosecutors.
