“I informed John Bolton last night that his services are no longer needed at the White House,” Trump tweeted Tuesday.
“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,” he continued. “I thank John very much for his service. I will be naming a new National Security Advisor next week.”
Bolton quickly disputed that he was fired, saying he offered his resignation Monday night.
Responding on "Outnumbered," Baier said Bolton's departure is not surprising, given that his "hawkish" positions are often at odds with Trump.
"It has been whispered for some time that he had fallen out of favor," said Baier, noting that Bolton had been excluded from high-profile meetings in recent months.
He said South Korea and Afghanistan objected to Bolton participating in meetings, with Bolton pushing back forcefully against Trump potentially negotiating face to face with Taliban representatives at Camp David.
Baier declined to speculate on who might replace Bolton, but said the potential candidates he's heard are "all people who have been in the administration previously."
