Rob Lowe left “The West Wing” after four seasons, and now he’s doing the same with ABC’s “Brothers & Sisters," reports The Hollywood Reporter.
Lowe started on the show, playing Sen. Robert McCallister, as a recurring character but quickly became a regular.
ABC said it would like to find a way to keep Lowe at the network. Entertainment President Steve McPherson said in a statement that "We feel he should be anchoring his own franchise. We are in talks now."
