Omarosa Manigault Newman says Americans should be worried about President Trump.

The former senior White House aide made her debut on the reality TV show “Big Brother: Celebrity Edition” Wednesday night.

“I was haunted by tweets every single day. Like, what is he going to tweet next?” she said, in a clip uploaded to YouTube on Thursday.

Omarosa said she tried to confront Trump about his behavior, but was attacked by other White House staff.

She said Americans should be worried.

“It’s going to not be ok. It’s not,” she said.

She served as director of communications for the White House’s Office of Public Liaison prior to her resignation in December 2017.

Manigault Newman had reportedly grown “fed up” with the way Trump handled racially charged issues, such as the violent neo-Nazi rally in Charlottesville.

Officials said she resigned, but sources claimed she had to be “dragged kicking and screaming from the White House.”
