Michael Flynn

President Donald Trump pardoned his former national security adviser Michael Flynn on Nov. 25, ending a yearslong prosecution in the Russia investigation that saw Flynn twice plead guilty to lying to the FBI and then reverse himself before the Justice Department stepped in to dismiss his case.

"It is my Great Honor to announce that General Michael T. Flynn has been granted a Full Pardon. Congratulations to General Flynn and his wonderful family", Trump wrote on his Twitter account and wished the Flynns happy holidays.
