CBS News reports:
Aggravation over Iran and the Taliban had intensified recently as Mr. Trump wanted a meeting to take place at Camp David and is open to a meeting with Iran’s president.
But three sources directly involved tell CBS News White House correspondent Major Garrett that the main irritant that drove Mr. Trump to distraction was his belief that Bolton or those close to Bolton leaked a story about Mr. Trump asking about whether nuclear weapons could be used to abate hurricanes.
Bolton’s resignation letter, obtained by CBS News, was extremely brief. “I hereby resign, effective immediately, as Assistant to the President for National Security Affairs. Thank you for having afforded me this opportunity to serve our country,” it reads.
