The sentencing of former Trump White House national security adviser Michael Flynn on a single charge of lying to the FBI turned into a dramatic scene in a Washington, D.C., courthouse Tuesday. Federal Judge Emmet Sullivan excoriated Flynn for what is called uncharged conduct — that is, for crimes that Flynn has not been formally accused of committing.

In open court, Sullivan raised the question of whether Flynn, a retired Army three-star general with more than three decades of service, might have committed treason. He questioned whether Flynn sold out the United States. He said Flynn had served as an unregistered foreign agent (for Turkey) inside the White House.
