Paul Manafort indicted in Robert Mueller's Russia probe

Donald Trump’s former campaign manager Paul Manafort turned himself in to the FBI Monday after being charged with conspiracy against the United States.

Manafort’s former business associate Rick Gates has also been told to surrender to federal authorities.

Manafort and Gates have been indicted on 12 charges, including “conspiracy against the United States, conspiracy to launder money, unregistered agent of a foreign principle, false statements, and seven counts of failure to file reports of foreign bank and financial accounts.”

The charges relate to the nine-year period from 2006 to 2015, when they acted as unregistered agents of the Ukraine government and former Ukrainian President Viktor Yanukovych.

Manafort is accused of laundering more than $18 million, which he used to buy property, goods, and services in the U.S. without reporting it to the Treasury.

Monday’s indictments are the first charges brought by Special Counsel Robert Mueller’s probe into Russian meddling in the 2016 U.S. election.

Mueller obtained the grand jury indictments Friday. Manafort and Gates were told to surrender to federal authorities Monday morning.

Manafort had been under investigation for violations of federal tax law, money laundering and whether he appropriately disclosed his foreign lobbying. The 68-year-old has denied any wrongdoing.

The lawyer and lobbyist worked as Trump’s campaign manager from June to August 2016, playing a crucial role in appointing Mike Pence as Trump’s running mate.

Gates and Manafort are longtime business associates, having worked together since the mid-2000s. Gates also worked on the Trump campaign.

Trump — who railed against Mueller’s investigation Sunday — was not named in the indictment and has not responded to the news; a White House spokesperson told CNN he “may not have a response at all.”

Mueller’s initial mission was to look into links or coordination between the Russian government and individuals associated with the campaign of President Donald Trump, but the probe has expanded in recent months.
