Two of the lawyers working for special counsel Robert Mueller – a group President Trump has repeatedly slammed as “17 angry Democrats” – have left his office, according to a report.

Ryan Dickey and Brian Richardson, both relatively junior prosecutors, had worked on court cases that Mueller launched as part of his probe into Russian meddling and possible collusion with Team Trump, CNN reported.

Peter Carr, a spokesman for the special counsel, said that neither Dickey nor Richardson have left because of political allegations, the appearance of bias or any other wrongdoing.

That suggests their departures appear to differ from that of Peter Strzok, a top FBI agent removed from Mueller’s team after it was discovered that he sent texts that disparaged Trump. He was later fired.

The special counsel’s office now has 15 lawyers working for Mueller, according to CNN.

In his frequent attacks of Mueller, a longtime Republican, on Twitter, the president has repeatedly referred to the lawyers in the office as “17 angry Democrats.”

Richardson had been among Mueller’s attorneys at the April sentencing of Dutch lawyer Alex van der Zwaan, who pleaded guilty to lying to investigators about his interactions with former Trump campaign leaders Rick Gates and Paul Manafort.

He went to prison for about a month and then left the US.

Richardson recently became a research fellow at Columbia Law School, CNN reported.

Dickey, who specializes in computer and intellectual property crimes, will continue to work at the Justice Department, according to the news outlet.

The Mueller-initiated cases Dickey was involved with include the indictment of 12 Russian military agents for allegedly hacking Democrats during the election.
