UPDATE | Ex-Trump aide pleads guilty, will cooperate in Russia probe

WASHINGTON (AP) — A former senior adviser to President Donald Trump's election campaign pleaded guilty today to federal conspiracy and false-statements charges, switching from defendant to cooperating witness in the special counsel's probe of Trump's campaign and Russia's election interference.

The plea by Rick Gates revealed he will help special counsel Robert Mueller's investigation in "any and all matters" as prosecutors continue to probe the 2016 campaign, Russian meddling and Gates' longtime business associate, one-time Trump campaign chairman Paul Manafort.

With his cooperation, Gates gives Mueller a witness willing to provide information on Manafort about his finances and political consulting work in Ukraine, and also someone who had access at the highest levels of Trump's 2016 presidential campaign.

Gates, 45, of Richmond, Va., made the plea at the federal courthouse in Washington. He stood somberly beside his attorney and did not speak during his hearing except to answer routine questions from the judge about whether he understood the rights he was giving up.

He admitted to charges accusing him of conspiring against the U.S. government related to fraud and unregistered foreign lobbying as well as lying to federal authorities in a recent interview. Under the terms of the plea, he is estimated to face between 57 and 71 months behind bars and a possible fine ranging from $20,000 to $200,000. Prosecutors may seek a shortened sentence depending on his cooperation.

The plea came a day after a federal grand jury in Virginia returned a 32-count indictment against Gates and Manafort, Trump's former campaign chairman, accusing them of tax evasion and bank fraud. Gates is the fifth defendant to plead guilty in Mueller's investigation.

The indictment in Virginia was the second round of charges against Gates and Manafort, who were initially charged last October with unregistered lobbying and conspiring to launder millions of dollars they earned while working on behalf of a pro-Russian Ukrainian political party.

Manafort continues to maintain his innocence.

"I had hoped and expected my business colleague would have had the strength to continue the battle to prove our innocence. For reasons yet to surface he chose to do otherwise," Manafort said today. "This does not alter my commitment to defend myself against the untrue piled-up charges contained in the indictments against me."

WASHINGTON (AP) — A former top adviser to President Donald Trump’s election campaign has formally pleaded guilty to federal conspiracy and false statements charges in the special counsel’s Russia investigation.

The plea by Rick Gates is a strong indication that he is planning to cooperate with special counsel Robert Mueller’s investigation as it continues to probe the Trump campaign, Russian election interference and Gates’ longtime business associate, Paul Manafort.

The 45-year-old Gates made the plea at the federal courthouse in Washington. It comes a day after Gates and Manafort were indicted in Virginia on new charges of tax evasion and bank fraud.

Manafort, who is Trump’s former campaign chairman, has said he is innocent.
