Chris Diamantopoulos Joins “24”

Chris Diamantopoulos has joined the “24” cast. He will play Rob Weiss, the new Chief of Staff to President Allison Taylor.

Chris Diamantopoulos — best known as Debra Messing’s gay BFF on The Starter Wife — has been tapped to play the series regular role of Rob Weiss, the argumentative and tough new Chief of Staff to President Allison Taylor (Cherry Jones). He replaces Taylor’s current C.O.S., Ethan Kanin, who snatched his job back in last Monday’s finale after the prez’s psycho daughter, Olivia, was taken into federal custody.

Season 8 is switching cities and will take place in New York City.
