"The Daily Show" says its executive producer is leaving.

Josh Lieb had held the post for four years, and the show announced Tuesday he's leaving to write a sitcom for Warner Bros. and NBC. He last year released the book "I Am a Genius of Unspeakable Evil and I Want to Be Your Class President."

Host Jon Stewart and Rory Albanese remain executive producers, but the Comedy Central show made other changes following Lieb's exit.

Three longtime staffers have been promoted to co-executive producer: Steve Bodow, Jennifer Flanz and Jim Margolis. They join Kahane Cooperman in the position.

Writer Tim Carvell has been elevated to head writer, and line producer Pam DePace will become supervising producer.
