"God no. Never. Not in a million years, never," Manigault Newman said on the season premiere of "Celebrity Big Brother" when asked if she would vote for her former boss again in the future. 

Manigault Newman also revealed on the reality television show that she was "haunted" by Trump's tweets and said the U.S. would not be okay under Trump's leadership. 

“I was haunted by tweets every day,” she said. “Like, what is he going to tweet next?”

“It’s going to not be OK, it’s not,” she said when asked if Americans should be worried about Trump. “It’s so bad.”

Manigault Newman resigned from the White House in December. 

She starred on NBC's "The Apprentice" during Trump's time as the reality show's host. The two maintained a working relationship after the season ended, CNN reports, and created a dating show called "The Ultimate Merger" in 2010.

She returned to Trump's "Celebrity Apprentice" in 2013 as a contestant. 

The White House fired back at Manigault Newman's comments on Thursday in a press briefing, saying she no longer has contact with Trump. 

“Omarosa was fired three times on ‘The Apprentice,’ and this was the fourth time we let her go,” deputy press secretary Raj Shah said. 

“She had limited contact with the president while here. She has no contact now.”
