"I believe there was tremendous misconduct on the government's behalf regarding my case," Papadopoulos told "Fox & Friends" host Brian Kilmeade. "And given certain information I learned just yesterday that I can't publicly disclose right now, I'm actually even considering withdrawing my agreement I have come to with the government."

Papadopoulos, who advised the Trump campaign on foreign policy issues and was sentenced in September to two weeks in jail, despite reaching a plea deal with Mueller for lying to investigators, said he believes he has been "set up" by the government and that his plea deal was the result of inadequate counsel.
