A court filing unsealed Friday and obtained by Politico showed Gates planned to plead guilty to conspiring to defraud the U.S. by hiding millions of dollars worth of payments that he received for work he did on behalf of the government of Ukraine. He also pleaded guilty to lying earlier this month about a March 2013 meeting with former Trump campaign manager Paul Manafort, a senior lobbyist for an unidentified company and an unidentified member of Congress.
Gates is expected to be required to cooperate with Mueller in the case against Manafort as part of the plea deal, Politico reported.
Gates and Manafort were indicted in October on a dozen charges connected to consulting work they did in Ukraine. In the 31-page indictment, federal prosecutors accused Manafort and Gates of conspiring against the United States, conspiring to launder money and working as unregistered foreign agents.
"They were required by law to report to the United States their work and fees," authorities said in the court records unsealed Friday. "Manafort and Gates did not do so. Instead, when the Department of Justice sent inquiries to Manafort and Gates in 2016 about their activities, Manafort and Gates responded with a series of false and misleading statements."
Both men pleaded not guilty last year. Manafort has not changed his plea.
In a statement obtained by the New York Times, Manafort said he had no plans to change his plea.
"I had hoped and expected my business colleague would have had the strength to continue the battle to prove our innocence," Manafort said. "For reasons yet to surface, he chose to do otherwise. This does not alter my commitment to defend myself against the untrue, piled-up charges contained in the indictments against me."
