WASHINGTON (AP) — The Latest on the Russia investigation (all times local):

A former top adviser to the Trump campaign is expected to plead guilty in special counsel Robert Mueller's Russia investigation.

A person close to Rick Gates say he is expected to enter the plea as early as Friday. The person spoke on condition of anonymity because they were not authorized to publicly discuss details.

A plea could signal that he's planning to cooperate with Mueller.

The plea comes a day after a federal grand jury in Virginia returned an indictment against him and former Trump campaign chair Paul Manafort accusing them of tax evasion and bank fraud. It was the second round of charges against the two men. They were 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.

Special counsel Robert Mueller has filed additional criminal charges against President Donald Trump's former campaign chairman and his business associate.

The Thursday filing adds allegations of tax evasion and bank fraud and significantly increases the legal jeopardy facing Paul Manafort, who managed Trump's campaign for several months in 2016, and longtime associate Rick Gates. Both had already faced the prospect of at least a decade in prison if convicted at trial.

The two men were initially charged in a 12-count indictment in October that accused them of a multimillion-dollar money-laundering conspiracy tied to lobbying work for a Russia-friendly Ukrainian political party. Manafort and Gates, who also worked on Trump's campaign, both pleaded not guilty after that indictment.
