Omarosa Manigault made her name as one of reality TV’s most notorious and hated personalities: the breakout star on season one of Donald Trump’s NBC series

Thirteen-years later, she is in the White House, not on a makeshift television set. But she’s still trying to win Trump’s favor and she still has the same villainous image she earned on NBC.

According to four sources in and outside the West Wing, the longtime Trump confidant is isolated inside 1600 Pennsylvania Avenue as she quietly plots against her fellow senior officials. Colleagues regularly complain about Manigault’s behavior and work ethic. She frequently derails internal meetings with irrelevant or counterproductive interjections and she’s earned a reputation for attempting to micromanage White House communications operations.

White House chief of staff John Kelly has tried to curtail Manigault’s direct access to the president, as The Daily Beast reported earlier this month. But her continued proximity to Trump—he speaks with her over the phone, even in the middle of the night—underscores just how thorny her tenure has been for those tasked with managing the administration.
