President Donald Trump’s campaign has filed for arbitration against Omarosa Manigault Newman for violating her nondisclosure agreement.

Trump campaign lawyers filed for the arbitration in New York on Tuesday saying the former White House aide violated an agreement she signed when joining the 2016 campaign, the Washington Examiner reported.

“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,” a Trump campaign official said in a statement.

“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 official added, according to the Washington Examiner.

Manigault Newman has turned on her former friend and boss, embarking on a media blitz promoting her tell-all book, “Unhinged: An Insider Account of the Trump White House.” She has claimed the president is a “racist, misogynist and bigot,” while releasing audio recordings in the last few days that she secretly took of Trump and campaign officials including chief of staff John Kelly who fired her in December.

The former “Apprentice” star may have potentially violated federal law by revealing the private conversations she had from the secret White House Situation Room.

Trump campaign advisers have denied the conversations she said occurred in a recording she released to CBS News on Tuesday claiming campaign staffers discussed a tape of Donald Trump using the n-word in the 2016 phone call.

Trump has slammed the former White House staffer as “crazed” and a “crying lowlife,” in a tweet on Tuesday, adding, “Good work by General Kelly for quickly firing that dog!”

Manigault Newman claimed that she hadn’t signed a nondisclosure for her White House work or for a 2020 campaign job which did not end up materializing. But the agreement during her 2016 campaign work which she did sign remains in effect as the campaign organization remained the same and never went out of force.

Arbitration demands are typically kept secret and the move by the Trump campaign “takes their fight to a whole new level and could wipe her out financially,” the Examiner reported.

“The campaign is holding her accountable for the 2016 nondisclosure,” a Trump ally said.

According to the Washington Examiner:

An official said on background that Manigault Newman has made “egregious” violations of the agreement and as a result they are seeking millions of dollars in retaliation. As the case unfolds, they might also seek any “ill-gotten profits” she has received from the book, including her fee for writing it. In an arbitration, which both sides agreed to in the nondisclosure agreement, each agree to an arbitrator, often a retired judge, who will hold a hearing and consider evidence. In the end the arbitrator will dismiss the case or issue a penalty. It has the full force of law. Typically the arbitration process moves faster than in a court.

Manigault Newman has 14 days to respond to the demand for arbitration from the Trump campaign.
