The appointment of Jon Lerner to Pence's team was one of the more short-lived personnel moves in a White House known for turbulent staff turnover and infighting, and the first to envelope the vice president, who works hard to stay out of the drama. But when Trump got wind of the agreement, he became furious.
The president believed Lerner, a longtime Republican strategist, was a card-carrying member of the "Never Trump" movement because he helped the conservative Club for Growth create ads as part of a multi-million dollar offensive against Trump during the GOP primaries.
"Why would Mike do that?"
"Last night, the objective of the mission of that (our) commander in chief gave our military forces was completely accomplished, with swift professionalism", Pence said in response to reporters' questions about whether Trump hastily overstated the mission's outcome.
Pence was present in Lima on behalf of the President of the United States Donald trump, who made a decision to remain in the United States to control the situation with military strikes against Syria.
But just hours later, Lerner stepped down, or "stepped down".
Pence's press secretary Alyssa Farah said in a statement, according to Axios: "Tonight Jon informed the vice president that he was withdrawing from coming on board as national security adviser". Lerner meant to continue working with Haley while advising the vice president, The Washington Post reported on Thursday.
It didn't help that others in the White House were unconvinced of Lerner's foreign-policy credentials and anxious that he wouldn't be able to handle two jobs at once.
