White House press secretary Sarah Huckabee Sanders sought on Friday to dispel reports that national security adviser H.R. McMaster could be replaced as soon as this month.

"Look, Gen. McMaster's not going anywhere," Sanders said on "Fox & Friends."

"As the president said yesterday in the Oval Office to a number of people, he thinks he's doing a great job," she said. "He's glad he's here."

Sanders's comments came after NBC News reported Thursday that White House chief of staff John Kelly John Francis KellyMORE and Defense Secretary James Mattis James Norman MattisBiden courts veterans amid fallout from Trump military controversies Trump says he wanted to take out Syria's Assad but Mattis opposed it Gary Cohn: 'I haven't made up my mind' on vote for president in November MORE are working on a plan to replace McMaster.

White House deputy press secretary Raj Shah said Thursday that the Trump administration had no announcements regarding McMaster's possible departure from the White House, but stopped short of an outright denial of the report.

"We frequently face rumor and innuendo about senior administration officials," he said in a statement. "There are no personnel announcements at this time."

Trump rebuked McMaster last month after the national security adviser said the evidence that Russia meddled in the 2016 presidential election was "incontrovertible."

"General McMaster forgot to say that the results of the 2016 election were not impacted or changed by the Russians and that the only Collusion was between Russia and Crooked H, the DNC and the Dems," Trump tweeted.
