On Thursday's Celebrity Big Brother, the 44-year-old reality star -- who first met Trump while a contestant on The Apprentice in 2004 -- emotionally opens up to housemate Ross Mathews about why she accepted the job as director of communications for the Office of Public Liaison, and what she now thinks of the commander in chief after officially resigning on Jan. 20.
"I felt like it was a call of duty. I felt like I was serving my country, not him," Omarosa, in a hushed voice, tells Mathews of taking on the role. "When accepting a political appointment, it was always about the country."
Recalling what it was like to work for Trump, Omarosa claims, "I was haunted by tweets every single day. Like, 'What is he going to tweet next?'"
"Does anybody say, 'What are you doing?'" Mathews asks.
Tearing up, Omarosa answers, "I mean, I tried to be that person, but then other people around him attacked me. It was like, 'Keep her away. Don't give her access. Don't let her talk to him.'"
"Who has that power to say, 'What's going on?'" says Mathews, inquiring further.
"I don't know. I'm not there. It's not my circus, not my monkeys," she responds. "I'd like to say not my problem, but I can't say that because it's bad."
"Should we be worried?" Mathews asks.
Omarosa shakes her head. "It's not going to be OK, it's not," she insists, tearing up even more. "It's so bad."
For more of Omarosa's candid conversation with Mathews, watch Celebrity Big Brother on Thursday night at 8 p.m. ET/PT on CBS. The three-night premiere event will then continue with a two-hour live eviction show on Friday at 8 p.m. ET/PT.
