But he noted the violation would likely be enough to deny Manigault Newman a security clearance if she ever wishes to work for the federal government in the future.
A reporter asked Trump "Do you feel betrayed by Omarosa sir?' to which he replied with a smile 'She's a lowlife". "She gladly, spitefully, wrecked her husband's directives to make him look foolish". The book called, "Unhinged: An Insider's Account of the Trump White House", will be released Tuesday.
On Twitter, Trump declared Monday that she had been "fired for the last time", a reference to her appearances on his reality TV show.
Manigault Newman also speculates about the "pussy bow" blouse Melania wore at one of the presidential debates in 2016, which took place right after the leak of the notorious "Access Hollywood" tape in which Trump made lewd comments about women.
Press secretary Sarah Huckabee Sanders also issued a statement saying that Unhinged "is riddled with lies and false accusations", adding that "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".

U.S. President Donald Trump and former aide Omarosa Manigault Newman faced off Monday in a messy clash that involved an explosive tell-all book, secret recordings and plenty of insults - reviving their roles as reality show boss and villain.
"I don't have that word in my vocabulary, and never have". And when I can tell my story, it is a profound story, that I know the world will want to hear.
He stated that he asked Chief of Staff General John F. Kelly to try and improve Ms Newman's performance as she had "only great things to say" about him.
"The allegation is not credible, and indeed is ridiculous, particularly in light of the timing of her departure from the White House-December 12, 2017", he said in an August 10 tweet. He offered her a "friendly departure", where she could resign to avoid damage to her reputation.
Trump officials and a number of outside critics denounced the recordings as a serious breach of ethics and security - and White House aides anxious about what else Manigault Newman may have captured in the West Wing.
All Trump campaign staffers were required to sign a nondisclosure agreement upon joining the campaign. "She's certainly violating national security regulations, which I think have the force of law", he said.
