President Donald Trump is replacing White House National Security Adviser H.R. McMaster with John Bolton, a former U.S. Ambassador to the United Nations famed for his hawkish views, in the latest shakeup of his administration.
“I am pleased to announce that, effective 4/9/18, @AmbJohnBolton will be my new National Security Advisor,” Trump said in a tweet. “I am very thankful for the service of General H.R. McMaster who has done an outstanding job & will always remain my friend. There will be an official contact handover on 4/9.”
