Law Professor Jonathan Turley reacted to news that Trump attorney Michael Cohen will invoke his Fifth Amendment rights in a defamation case brought by pornographic film star Stormy Daniels.

Daniels, whose real name is Stephanie Clifford, is taking Cohen to court in California, Martha MacCallum reported.

"It is a rather low moment [for Cohen]," Turley, of George Washington University in Foggy Bottom, D.C., said.

"And, it's going to be a bad moment for the president," he added.

For Trump, Turley said the proceedings on both coasts involving Cohen present bad "optics" for Trump.

"It's like being represented by Luca Brasi," he said, referring to the violent mob enforcer employed by "Godfather" character Vito Corleone.

Turley said that Daniels' attorney Michael Avenatti is his former research assistant and that the lawyer is creating a "mess" for Cohen.

Cohen "has fallen into every trap that Avenatti has set for him," Turley said, adding that Trump "should've severed ties with Cohen."
