In her new memoir, "Unhinged," the former White House adviser Omarosa Manigault Newman claims she once saw President Donald Trump eating a piece of paper in the Oval Office, The Washington Post said.

"Since Trump was ever the germaphobe, I was shocked he appeared to be chewing and swallowing the paper," Manigault Newman wrote, according to The Post.

Cohen said he did not see Trump consume paper.

Manigault Newman had a brief but chaotic tenure at the White House, leading to questions about the credibility of the claims she makes in her book.

The former White House adviser Omarosa Manigault Newman claims in her forthcoming memoir that she once saw President Donald Trump eating a piece of paper in the Oval Office, The Washington Post reported Friday, citing excerpts it obtained.

In the book, "Unhinged," Manigault Newman said she saw Trump chewing up a piece of paper given to him by his former lawyer Michael Cohen, The Post said.

"I saw him put a note in his mouth," Manigault Newman wrote, according to the newspaper. "Since Trump was ever the germaphobe, I was shocked he appeared to be chewing and swallowing the paper. It must have been something very, very sensitive."

White House aides "laughed at the assertion and said it was not true," The Post reported.

Cohen also addressed Manigault Newman's claim regarding Trump consuming paper in a tweet on Monday, stating, "I saw NO such thing and am shocked anyone would take this seriously."

Manigault Newman's book has already generated a fair amount of controversy.

In the memoir, she claims Trump used racial slurs like the N-word on tape while hosting "The Apprentice," a show on which she was a contestant before following Trump into the world of politics.

The White House press secretary, Sarah Huckabee Sanders, on Friday said Manigault Newman's book was "riddled with lies" and bashed the media for giving her "a platform."

Sanders described Manigault Newman as a "disgruntled former White House employee" who was making a "sad" attempt to profit off "false attacks" against the president.

Manigault Newman had a brief but chaotic tenure at the White House, leading to questions about the credibility of the claims she makes in her book.

"Unhinged: An Insider's Account of the Trump White House" comes out on August 14.
