Flynn resigns. Gen. Kellogg acting NSA

Michael T. Flynn resigned Monday night as President Donald Trump’s national security adviser after it was revealed that he had misled Vice President Mike Pence over his conversations with the Russian ambassador about US sanctions weeks before Trump’s inauguration. Flynn, less than a month in the job, had previously denied that he had any substantive conversations with Ambassador Sergey I. Kislyak, and Pence repeated that claim in television interviews. The White House announced he was being replaced with retired Lt. Gen. Joseph K. Kellogg Jr. of the Army, a Vietnam War veteran, as acting national security adviser.
