A former Trump campaign aide is reportedly working on a plea deal with special counsel Robert Mueller and could be cooperating in the Russia investigation.

Rick Gates — the former aide indicted on a slew of charges — offered information to Mueller’s team and has been negotiating a plea deal for about a month, according to CNN.

If he were to take a deal, he would be the third former Trump aide to cooperate with Mueller’s probe into Russia election interference.

Gates was indicted along with former Trump campaign manager Paul Manafort in late October.

Gates and Manafort face charges including conspiracy to launder money, conspiracy to defraud the United States, and failure to register as foreign agents in connection with their political work for a pro-Russia Ukrainian party. Both pleaded not guilty.

Gates hired a new attorney last month, CNN reported, signaling that he was changing directions in his defense.

One White House official downplayed the significance of Gates’ action.

“There’d be no anxiety here” if Gates cooperated with Mueller, the official told the cable network.

Former Trump campaign foreign policy adviser George Papadopoulos previously pleaded guilty to making a false statement to the FBI after he lied about his interactions with foreign officials close to the Russian government.

Mike Flynn, who served as Trump’s national security adviser, was the first former presidential aide to plead guilty to lying to the FBI about his contacts with Russians.
