Trump rips ex-aide over tell-all book: 'He was nothing more than a gofer'

President TrumpDonald John TrumpTrump's newest Russia adviser, Andrew Peek, leaves post: report Hawley expects McConnell's final impeachment resolution to give White House defense ability to motion to dismiss Trump rips New York City sea wall: 'Costly, foolish' and 'environmentally unfriendly idea' MORE on Tuesday lashed out at Cliff Sims on the day the former White House staffer's book detailing his time in the administration was released, dismissing him as "low level" and "nothing more than a gofer."


"A low level staffer that I hardly knew named Cliff Sims wrote yet another boring book based on made up stories and fiction," Trump tweeted.

"He pretended to be an insider when in fact he was nothing more than a gofer. He signed a non-disclosure agreement," he added. "He is a mess!"

The tweet marked the first time Trump has publicly commented on Sims's book. The president did not dispute any specific claims in the book.

Excerpts of the tell-all, "Team of Vipers," have been published in recent days, and Sims on Monday appeared on "Good Morning America" and "The Late Show With Stephen Colbert."

During his roughly 18 months in the Trump administration, Sims served as director of White House message strategy and a special assistant to the president, sitting in on high-level meetings. He left his position last May.

In excerpts released from the book, Sims has described sitting with Trump and creating a list of problematic individuals working in the White House.

In another excerpt, Sims portrayed White House counselor Kellyanne ConwayKellyanne Elizabeth ConwayWhite House pushes back on Parnas allegations Trump suggests LBJ is in hell: 'He's probably looking down — or looking up' George Conway group releases ad targeting GOP senator: 'You're just another Trump servant' MORE as a "cartoon villain brought to life" who bad-mouthed other staffers to the press.

Sims also wrote that White House senior adviser Stephen Miller derided immigrants and refugees and said he'd be happy if "not a single refugee foot ever again touched American soil."

White House press secretary Sarah Huckabee Sanders on Monday said she'd never heard Miller make such comments.

Michael Glassner, the chief operating officer of the Trump campaign, on Tuesday tweeted that the campaign is preparing to sue Sims over violating a nondisclosure agreement. The campaign took similar action against former staffer Omarosa Manigault NewmanOmarosa Onee Manigault NewmanThe Memo: Impeachment's scars cut deep with Trump, say those who know him Author of anonymous 'resistance' NYT op-ed to publish book Juan Williams: Black Republicans call out Trump — finally — on race MORE upon release of her book last year.

Sims's book is the latest in a string of tell-all books that have been written about the Trump White House. Manigault Newman, veteran journalist Bob Woodward and author Michael Wolff each wrote books that described the administration as a chaotic environment where the president and his advisers disparaged one another on a regular basis.

In each case, the president has lashed out at the author and pushed back against the claims made in the book. Trump called Woodward an "idiot," Manigault Newman a "dog" and described Wolff's work as a "fake book."

Each of those books eventually rose to No. 1 on The New York Times's best-seller list.
