But he said he has "no idea" which "senior administration official" wrote last week's anonymous New York Times op-ed stating that some within the White House are actively working to stop Trump from acting out on certain impulses.
The report quoted an unnamed White House official as saying that speculation about a replacement was now "more real than ever" after revelations in famed investigative journalist Bob Woodward's upcoming book titled Fear: Trump in the White House.
According to the book Rear Admiral Ronny Jackson, Trump's doctor until earlier this year, repeatedly advised John Kelly, his chief of staff, to "dial back" the president's schedule because he was "under stress".
Trump said if the person had a high-level security clearance, "I don't want him in those meetings".
"The root of the problem is the president's amorality", wrote the official.
First Lady Melania Trump also weighed in to address the writer of the op-ed through her spokesperson.

Do I wish that every single thing I did when I was 19 wasn't a discussion? On Thursday he tweeted: "I just wanna go on tour". He had allegedly wrecked his Mercedes-Benz G Class vehicle by slamming into a utility pole, and fled the scene of the crash.
Addressing the steady drip-drip-drip of excerpts from Woodward's book "Fear", CNN host Victor Blackwell said that Trump is not happy with former Fox exec Shine, who he feels has not been as effective as former Trump confidante Hope Hicks.
Woodward said staffers did so "because they realized that this would endanger the country". The criticism of Trump is on-point and damning, as it should be, as it has no other way to be for a President who surrounded himself with associates many of whom are now felons.
"He's wrong, and my reporting is meticulous and careful", Woodward said, affirming even the most eyebrow-raising passages in his book.
Trump has said the Justice Department should investigate and unmask the anonymous New York Times author. We also learned that Gary Cohn, one of President Trump's advisors, lifted a letter off Trump's desk so that the president wouldn't act on his worrisome threat to scuttle a trade deal with South Korea.
Glenn Kessler, the Washington Post's fact-checker, seized on Dao's explanation of how the New York Times made a decision to describe the author.
Trump's comment Friday that Attorney General Jeff Sessions should investigate who wrote the newspaper op-ed isn't the first time he has demanded that the Federal Bureau of Investigation or Justice Department look into a disclosure that is embarrassing to the White House.
But Trump lambasted Woodward's account as a "phony story".
The piece says administration officials have discussed the possible use of the 25th Amendment. On a more serious note, Pelosi said that Trump's reaction to the op-ed is a "manifestation of his instability" and that the author's supposed actions to subvert the president are insufficient.
