Donald Trump wasn’t the first person to fire Omarosa Manigault-Stallworth, the combative “Apprentice” contestant who makes a heralded return to the NBC reality show on Thursday, the next-to-last episode of the ratings hit.

According to the new issue of PEOPLE, the former political appointee — who spoke glowingly of her White House days — was banished from four jobs in two years with the Clinton administration.

At her last one, “she was asked to leave as quickly as possible, she was so disruptive,” says Cheryl Shavers, the former Under Secretary for Technology at the Commerce Department, where Omarosa worked several weeks in 2000. “One woman wanted to slug her.”

Manigault-Stallworth, 30, was also bounced from a previous position at Commerce, says another former administration official, “because she couldn’t get along with people.”

At her first White House gig, answering invitations received by Vice President Al Gore, “she didn’t do her job, and it got everybody in trouble,” says a former Gore staffer.
