Gidley also stated that Charles Kupperman is serving as Acting National Security Adviser.
Bolton previously served as Ambassador to the United Nations under the administration of former President George W. Bush. Trump appointed Bolton to replace H.R. McMaster, who also resigned due to his frequent disagreement with Trump on different issues.
McMaster replaced Michael Flynn, who was first appointed by Trump as National Security Adviser. Flynn’s tenure at the White House was short because of his involvement with Russians. Flynn pleaded guilty to lying to the Federal Bureau of Investigation (FBI) regarding his conversations with then-Russian Ambassador Sergey Kislyak. He agreed to cooperate with former Special Counsel Robert Mueller’s investigation into the alleged interference of the 2016 presidential election by Russians.
