The Hill is reporting MSNBC anchor Rachel Maddow has joined the cast of Batwoman.

“The political talk show host will play the role of Vesper Fairchild, a radio personality who was romantically involved with Bruce Wayne — also known as Batman — on the CW’s series about the lesbian superhero.”

Maddow has joined for multiple episodes, but there are no plans so far for her to appear on screen.

“We consider Vesper Fairchild to be the sardonic Voice of Gotham,” showrunner Caroline Dries told The Hollywood Reporter in a statement. “In addition to Rachel’s interest in Batwoman, we thought she’d be the perfect casting choice because her own hard-hitting journalism wildly contrasts Vesper’s penchant for snark, gossip and criticism of female superheroes.”

Maddow also penned an introduction for the deluxe hardcover edition of a 2010 Batwoman graphic novel.
