Michael Flynn, Trump's short-lived national security adviser, is still awaiting sentencing after initially pleading guilty to lying to the FBI as part of the Mueller probe.
The retired Army general got in trouble over not being forthcoming about his contacts with Sergey Kislyak, the then-Russian ambassador to the U.S., which spiraled into the scandal that led to the president firing FBI Director James Comey and Mueller's ultimate appointment.
Flynn hasn't exactly acted like a normal defendant. While he did cooperate with the special counsel's investigators, Flynn later fired his original legal team and replaced them with an attorney known for her outspoken criticism of the FBI and Mueller's investigators.
The lawyer, Sidney Powell, has requested to have Flynn's plea agreement withdrawn, alleging the FBI tricked him into making false statements.
His sentencing has been postponed several times, most recently in February. The coronavrius pandemic should delay that even further, while the prospect of a Trump pardon also looms large in the picture.
