Paul Manafort, President Trump’s former campaign chairman, and Rick Gates, Manafort’s former business partner, were indicted by a federal grand jury on 12 counts, including conspiracy against the United States, special counsel Robert Mueller’s office said Monday. The 31-page indictment was unsealed by a federal judge in Washington, D.C., on Monday morning after Manafort and Gates surrendered to the FBI. The charges are the first brought by Mueller since he was appointed in May to lead the federal probe into Russian interference in the 2016 presidential election.

Mueller’s office also announced Monday that former Trump campaign adviser George Papadopoulos pleaded guilty this month to making false statements to FBI agents about his contacts with Russians during the campaign. Papadopoulos was arrested in July and cooperated with federal officials in their investigation.
