In a clip from an episode of the CBS reality show that aired Thursday, Newman’s co-star and reality TV star Ross Matthews asks her, “Should we be worried?”
Newman nods "yes" with tears in her eyes, saying, “It’s not going to be OK. It’s not.”
She also claimed on Thursday's episode she would never vote for Trump again, telling Matthews, "God no. Never. In a million years, never."
Newman, who says she resigned in December as director of communications for the Office of Public Liaison, claims she was haunted by the president’s tweets.
“I was haunted by tweets every single day. Like, what is he going to tweet next?”
“They would say: 'Keep her away from him,'” Newman said. "'Don’t give her access, don’t let her talk to him.'"
The White House said it didn't take her comments "very seriously."
Newman first became famous in 2004 starring with Trump on NBC's "The Apprentice." Trump invited her back for round two, this time in "Celebrity Apprentice" in 2008, only to have Trump "fire" her again.
Newman has not responded since the White House comment, but did showcase a big smile in a Twitpic thanking “Celebrity Big Brother” fans for tuning in to the season premiere.
