Update: Kal Penn Leaves House to Join House

So, we finally have an answer as to why Kal Penn decided to leave the Fox series House. He's joining a different House...

The demise of Penn's character cleared the way for the actor to move on to another "House," the White House.

Penn, 31, will be an associate director for the Obama administration's Office of Public Liaison.

"It seemed like something I would enjoy doing," Penn said. "I figured it was something to do."

He's not retiring from acting, just pursuing a longtime desire for public service that was rekindled when he campaigned for Barack Obama's election, Penn said.

So cool! Good luck to Kal Penn in his new job!
