Bolton has served in the Republican administrations of Ronald Reagan, George H.W. Bush and George W. Bush, and served as a Bush lawyer during the 2000 Florida recount.
A strong supporter of the Iraq war and an advocate for aggressive use of American power in foreign policy, Bolton was unable to win Senate confirmation after his nomination to the U.N. post alienated many Democrats and even some Republicans. He resigned after serving 17 months as a Bush "recess appointment," which allowed him to hold the job on a temporary basis without Senate confirmation.

Trump called the Iraq invasion "the single worst decision ever made" and said it amounted to "throwing a big fat brick into a hornet's nest."
"That was Bush. Another real genius. That was Bush," Trump said sarcastically. "That turned out to be wonderful intelligence. You know? Great intelligence agency there."
