Robert Manafort was the main target of reports last week after Mueller had gotten a court to approve charges. He has now turned himself in:

REUTERS – Paul Manafort, a former campaign manager for U.S. President Donald Trump, surrendered to federal authorities on Monday in the first charges stemming from a special counsel investigation of possible Russian meddling in the 2016 U.S. presidential election, according to media reports.

Manafort arrived at the Federal Bureau of Investigation Washington field office, television video showed. He was to surrender to federal authorities, the New York Times and CNN reported, citing sources.

The charges against Manafort would be the first arising from the investigation by Justice Department special counsel Robert Mueller, who was appointed to look into alleged Russian meddling to sway the election in favor of Trump.

The charges against Manafort would include tax fraud, according to the Wall Street Journal.

A federal grand jury issued the indictment on Friday and a federal judge ordered it sealed, a source briefed on the matter told Reuters, adding it could be unsealed as soon as Monday.

Manafort associate Rick Gates would also surrender, the Times reported.

Lawyers for Gates and Manafort would not immediately return calls for comment.
