President Donald Trump's deputy national security adviser, K.T. McFarland, is leaving the White House and will be nominated to become USA ambassador to Singapore, according to a source close to the situation.
McFarland was a national security analyst for Fox News and worked under three Republican administrations before she was tapped for the role as Trump's deputy national security adviser.
McFarland, who was named to her post by the previous national security adviser, Michael Flynn, was initially told that she could remain at the White House when Flynn was replaced by H.R. McMaster. Trump fired Flynn in February amid revelations Flynn misled senior administration officials about his contacts with Russian government officials.
On Thursday, as the President met with top national security and cabinet officials in a newly built situation room at Mr Trump's Florida resort to trigger United States missile strikes on Syrian government installations, Ms Powell was among the attendees. The administration is still awaiting approval from Singapore and the post requires Senate confirmation. Powell joined the White House to work with Trump daughter Ivanka on women's empowerment issues.
But Powell soon began attending senior-level staff meetings with the president himself.
McFarland will not be leaving the administration, however, as she will reportedly be nominated to be the US ambassador to Singapore, a significantly lower-profile role, which will be subject to Senate confirmation. Last week, he led a restructuring of the NSC, removing White House chief strategist Stephen Bannon from the principal's committee and diminishing the power of homeland security adviser Tom Bossert within the committee.
"She is going to do it, assuming she gets confirmed", the official said.
