DEBKAfle: Mike Flynn’s forced resignation as National Security Adviser throws the Trump administer into its first crisis. Flynn was one of Donald Trump’s most vocal supporters in his campaign for president and loyal advisers of his administration. The National Security Council he headed is composed almost entirely of military figures whom he personally picked. His successor may decide to rebuild the key body from scratch. Meanwhile, retired Lt. Gen. Joseph K. Kellogg Jr. of the Army will serve as acting national security adviser. Prime Minister Binyamin Netanyahu’s Washington visit begins amid unforeseen political turbulence in Washington. Flynn’s resignation is bound to affect its decisions on security issues. Some decisions may be held in abeyance until a new National Security Adviser is appointed in the White House.
