When news that Omarosa Manigault Newman was fired from Trump’s administration on December 12, the former reality star launched a press tour, speaking adamantly about the the things she “knows” from working behind the scenes at the White House.

Though denying she was fired, Omarosa went on Good Morning America, saying, “There were a lot of things I observed over the past year that I was uncomfortable with. When I have the chance to tell my story, it’s quite a story to tell.”

Apparently, insiders at Life & Style magazine say that Omarosa’s potential tell-all book could be worth as much as $10 million, and it could be devastating to Donald and Melania’s marriage.

Other sources close to Omarosa told In Touch that they believe Omarosa intends to betray Donald and Melania by spilling dark secrets about their marriage.

“This could be Donald and Melania’s worst nightmare,” says one Washington, D.C., insider. Political analyst Peter Mathews agrees, telling In Touch that a book focusing on the president’s marriage “would be very damaging. Who knows how he treats Melania in the White House and vice versa.” Omarosa is a huge threat because of the bombshell secrets she may know: “If I were President Trump,” Mathews adds, “I would rather have had her on my staff still.”
