President Donald Trump's former campaign manager Paul Manafort and Manafort's former business associate Rick Gates are expected to surrender to federal authorities Monday morning, the New York Times reported.

CNN first reported Friday that special prosecutor Robert Mueller had obtained grand jury indictments, which remained sealed over the weekend.

Mueller has been charged by the Department of Justice with investigating "any links and/or coordination between the Russian government and individuals associated with the campaign of President Donald Trump," according to an order issued in May by Deputy Attorney General Rod Rosenstein. The order also empowered him to probe other matters that "may arise directly from the investigation."

Manafort has reportedly been under federal investigation for his overseas financial dealings, possible tax crimes, and potential failures to follow lobbying laws.
