Trump campaign files arbitration action against Omarosa for NDA breach

The Trump campaign has filed an arbitration action against former White House staffer Omarosa Manigault Newman, citing a breach of her 2016 nondisclosure agreement after her release of multiple secret recordings of Trump administration and campaign officials, per The Washington Examiner.

The big picture: This is a notable escalation in an already nasty battle between Omarosa and President Trump, who called her a "dog" in a controversial tweet Tuesday morning. Trump noted in a tweet on Monday that she completed "a fully signed Non-Disclosure Agreement" — just hours after she released a recording of a phone call with Trump that allegedly took place the day after her firing by Chief of Staff John Kelly.
