A staff member of Donald Trump’s 2016 Presidential campaign filed a lawsuit in federal court in Florida on Monday, alleging that she experienced “racial and gender discrimination” while working for the campaign, that she was paid less than male and white colleagues, and that Trump once kissed her partially on the mouth, without her consent. The claim related to the kiss may prove difficult to verify. Four people said that the campaign worker, Alva Johnson, told them about the incident afterward, but two other people, who Johnson said were present at the time of the kiss, told me that they did not see it. In a statement, Sarah Sanders, the White House press secretary, denied that it had taken place.

The most legally significant aspect of Johnson’s suit may ultimately be something the complaint does not explicitly address: the pervasive use of nondisclosure agreements by Trump during his campaign and in his Administration. Johnson’s suit is at least the sixth legal case in which Trump campaign or Administration employees have defied their nondisclosure agreements. Three of those actions, including Johnson’s, were filed this month. Johnson, who was the campaign’s administrative field-operations director in Florida, signed a nondisclosure agreement that bars her from revealing any information “in any way detrimental to the Company, Mr. Trump, any Family Member, any Trump Company or any Family Member company.” Johnson’s attorney, Hassan Zavareei, said, “We expect that Trump will try to use the unconscionable N.D.A. and forced arbitration agreement to silence Ms. Johnson. We will fight this strong-arm tactic.”
