Fox News with more:

President Trump fired John Bolton as National Security Advisor last week.

Trump said he “disagreed strongly” with many of Bolton’s suggestions.

“I informed John Bolton last night that his services are no longer needed at the White House. I disagreed strongly with many of his suggestions, as did others in the Administration, and therefore I asked John for his resignation, which was given to me this morning. I thank John very much for his service. I will be naming a new National Security Advisor next week,” Trump said last week in a pair of tweets.

Bolton told reporters that he wasn’t fired, rather he offered to resign.

John Bolton served as National Security Advisor under President Trump after General H.R. McMaster was forced out of the position in March of 2018.

General Mike Flynn briefly served as President Trump’s first National Security Advisor and was forced out after the Deep State leaked his phone calls with Russian Ambassador Kislyak to the Washington Post.
