A March 8 article in Cosmopolitan magazine about the lawsuit a porn star his filed against Donald Trump features insights from Professor David S. Cohen.

In her lawsuit, Cohen explained, Stormy Daniels seeks to have a court void a non-disclosure agreement designed to prevent her from publicly discussing her alleged affair with Donald Trump.

“If she were to go ahead and talk about the affair, she’s afraid she would be sued by Trump’s people for violating the non-disclosure agreement,” Cohen said. “It’s preemptively asking the court to say whether she’s allowed to talk or not.”

Calling the non-disclosure agreement a “colloquial, slightly sinister term,” Cohen explained that such an agreement is fine in most circumstances.

“It gets tricky if the campaign’s involved,” Cohen said.

While Daniels’ attorney has said the agreement is invalid because Trump never signed it, Cohen said a court will determine it was merely an administrative error.
