Omarosa makes a vicious accusation against Trump - but Frank Luntz says it's a lie

Former contestant on "The Apprentice" and White House aide Omarosa Manigault made a heinous accusation against President Donald Trump, but pollster Frank Luntz contradicted her on social media and said it was an utter lie.

"Very shoddy work"

Manigault claims in her upcoming book that the president used the offensive "n-word," and even implies that her attempt to find a tape of his using the word led to her being fired from the White House.

She says that Trump can be heard saying the word in a recording of an outtake from his show "The Apprentice."

But when he heard the claim, Luntz tweeted that the accusation was completely false.

"I’m in @Omarosa’s book on page 149," Luntz tweeted. "She claims to have heard from someone who heard from me that I heard Trump use the N-word."

"Not only is this flat-out false (I’ve never heard such a thing), but Omarosa didn’t even make an effort to call or email me to verify," he added. "Very shoddy work."

"It seems like certain book publishers these days care more about getting a release out than getting the facts down," Luntz added in a second tweet.

"This is why people don’t trust these 'exposés,' which is especially bad for authors who actually are good and reliable," he concluded, referring to Manigault's book.

In an interview with NPR, Manigault appeared to give a different account of what happened than what was in the book. "This discrepancy in her account of hearing the tape may cast doubt on other claims in the book, many of which are explosive," noted NPR's Tamara Keith.

The White House strikes back

The White House responded to Manigault's book with a scathing statement Friday.

"Instead of telling the truth about all the good President Trump and his administration are doing to make America safe and prosperous, this book is riddled with lies and false accusations," said White House press secretary Sarah Sanders in the statement.

"It's sad that a disgruntled former White House employee is trying to profit off these false attacks, and even worse that the media would now give her a platform, after not taking her seriously when she had only positive things to say about the President during her time in the administration," she added.
