The White House on Thursday faced fresh speculation about the future of national security adviser H.R. McMaster, with officials sending mixed messages about his possible departure.
Amid a stream of staff leaving Donald Trump's White House, NBC reported that the three-star general tasked with running White House security policy would, within months, be headed for the exit as well.
"We frequently face rumor and innuendo about senior administration officials," White House spokesman Raj Shah said in response. "There are no personnel announcements at this time."
That was followed up by a more categorical statement from McMaster's spokesman, Michael Anton.
"I was just with President Trump and H.R. McMaster in the Oval Office. President Trump said that the NBC News story is fake news, and told McMaster that he is doing a great job," Anton said.
NBC reported that a senior executive at U.S. automaker Ford, Stephen Biegun, was a possible replacement.
Biegun previously worked as national security adviser to former Senate Majority Leader Bill Frist, a Tennessee Republican, and worked in the George. W. Bush White House.
Trump and McMaster have had an uneasy relationship.
When the army general recently said there was "incontrovertible" evidence of Russian interference in the 2016 presidential election, he was publicly upbraided by Trump.
"General McMaster forgot to say that the results of the 2016 election were not impacted or changed by the Russians," Trump tweeted.
McMaster joined the administration in February last year, replacing Michael Flynn, who has since been indicted by Robert Mueller, who is investigating Russia's role in the 2016 election and whether there were connections between the Trump campaign and Moscow.
Last week, CNN reported that the Pentagon was looking at moving McMaster back into the military.
