“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,” Trump said on Twitter.
....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.

Ambassador Bolton sends me a text message just now: “Let’s be clear, I resigned, having offered to do so last night.”

But yes, Bolton's exit will definitely impact Trump admin's Iran policy. Trump-Rouhani summit is being considered very seriously - and I'm in fact told that it is already finalized. Bolton would have had no role in that, so from that perspective his exit makes sense.

Good question.

Indian govt should be happy with Bolton's exit. Bolton was not very pro-India and he opposed India's bid for UNSC membership as well as India-US nuclear deal. Bolton was also somewhat pro-Pakistan and opposed hard stance against Pakistan. https://t.co/su2mIqlJyY

Question : now that @AmbJohnBolton is gone does that mean the President can foresee a meeting btw him and The Iranian leader later this month (at UN) @SecPompeo says "Sure. The President has made it clear he's prepared to meet with no preconditions"

Let me be clear: I think many of Bolton's views are borderline dangerous. But he was the ONLY remaining member of the president's inner circle who knew anything about strategic affairs. If you think things have been chaotic to this point, just wait… https://t.co/nX6D8zvLrz
