Omarosa Manigualt Newman

Omarosa Manigualt Newman’s new tell-all book book promises to give readers an insider’s look into the Trump White House. Omarosa worked as an assistant to President Donald Trump before she was fired and “forcibly removed” from the White House.

In her book, Omarosa, 44, said Trump exhibited “mental decline that could not be denied” after she watched Trump’s recent interview with Lester Holt last May.

“Throughout this erratic and contradictory interview, I kept thinking, ‘Oh No! Oh No! This is bad!” she wrote in an exclusive excerpt obtained by UK’s DailyMail.com.

“While watching the interview I realized that something real and serious was going on in Donald’s brain. His mental decline could not be denied,” she wrote.

Months after Trump was elected president, Omarosa, who first met Trump when she appeared on The Apprentice, ran afoul of West Wing staffers when she brought her 39-person wedding party to the White House for a photo shoot without permission.

The end for Omarosa came in February when she was fired by chief of staff John Kelly for abusing the White House car service, according to Politico.com.

A loud argument ensued and Omarosa was carried off the White House grounds.

According to Politico.com, Omarosa used the White House car service “as an office pick-up and drop-off service” — which is strictly forbidden.

After she was fired, Omarosa said she would “never vote for Trump again in a million years,” and she expressed concern about Vice President Mike Pence.

“He’s extreme. I’m Christian, I love Jesus, but he thinks Jesus tells him to say things,”she told fellow contestants on Celebrity Big Brother.
