Federal prosecutors have reached a plea deal with Maria Butina, the Russian woman who parlayed her interest in gun rights and her Republican Party connections into an unofficial influence campaign inside the U.S.
Butina has agreed to plead guilty to a single charge of conspiracy to act as a Russian agent on America's soil without registering as required with the Justice Department.
She faces a maximum of five years in prison but could serve far less time once she is sentenced next year.
