CBS NEWS-- President Trump's former 2016 campaign chairman Paul Manafort and Rick Gates, Manafort's former business associate, are charged with money laundering and conspiracy in connection with the investigation into Russian meddling in the U.S. presidential election.

Manafort and Gates were told to surrender to federal authorities Monday morning.

CBS News spotted Manafort leaving his apartment in Alexandria, Virginia Monday morning with his lawyer. A federal grand jury used by Special Counsel Robert Mueller approved the first charges stemming from the investigation, CBS News reported Friday.

The indictment accuses both Manafort and Gates of acting as unregistered agents of the Ukrainian government. It also says that both men received tens of millions of dollars in income for their work.
