Cooper mocked Grisham, calling her dishonest during his "Ridiculist" segment on "Anderson Cooper 360" on Friday evening, and tore into her defense of Mulvaney after the acting chief of staff walked back the comments he had made hours earlier at a rare White House press briefing.

"Does everyone working for the president have to debase themselves and lie like he does? Apparently so. I thought John Grisham was a great storyteller, but I got to say, Stephanie Grisham may have him beat," Cooper said.

"Ms. Grisham clearly doesn't get to Broadway enough if she thinks those press conferences are theatre."

The CNN host also took aim at Grisham's suggestion that White House press conferences had devolved into "theater" due to reporters being eager to get on television.

"Ms. Grisham clearly doesn't get to Broadway enough if she thinks those press conferences are theater," Cooper said, adding, "Maybe on one of the seven days a week she isn't doing her job, she can catch maybe a matinee of 'Hamilton.'"

Grisham did not immediately return a request for comment from The Hill on Saturday.
