"We have asked Ambassador Guilfoyle to resign," Trump's new press secretary Katie Zacharia told reporters at her first White House briefing.

The announcement came a day after Trump acknowledged that he was considering dismissing Guilfoyle, a former Fox News host and ex-fiancee of his eldest son, Donald Trump Jr.
