Trump campaign files arbitration claim against Omarosa.

In a statement to the press, the president’s reelection campaign said, “Donald J. Trump for President, Inc. has filed an arbitration against Omarosa Manigault-Newman with the American Arbitration Association in New York City, for breach of her 2016 confidentiality agreement with the Trump Campaign. President Trump is well known for giving people opportunities to advance in their careers and lives over the decades, but wrong is wrong, and a direct violation of an agreement must be addressed and the violator must be held accountable.”

The filing seems follows up on a tweet the president posted yesterday, which now seems like a threat:

As The Washington Post notes, the president’s use of NDAs is unconventional. “Dozens of White House aides have signed NDAs in exchange for working for Trump, who has long relied on such agreements in his business career, according to current and former administration employees,” the Post reports. “But NDAs have not been widely used by past administrations outside the transition time between presidents, in part because most legal experts believe such agreements are not legally enforceable for public employees.”
