Trump's announcement is unusual. While he has tweeted on many occasions such a statement regarding high ranking officials who were asked to leave, he used to praise those who are leaving the administration with kind and warm words. The fact that the president chose to mention that he "disagreed strongly with many of his suggestions," offers a glimpse to the tensions behind the scenes between Bolton and other White House officials.CNN reported Friday that Bolton "rarely speaks outside of formal meetings" with Secretary of State, Mike Pompeo, according to three sources, including a recent stretch of going weeks without speaking to one another.In addition, the report indicated an "all-out hostility, creating a deep disconnect between staffers on the National Security Council, led by John Bolton, and the rest of the administration."....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.
