why did kutner leave house

Kutner, a character on the TV show House MD, was written out through an unexpected suicide in season 5. The real reason for this plot decision was that the actor playing Kutner, Kal Penn, decided to leave the show to take a job in the White House Office of Public Engagement under President Barack Obama. His departure was not due to any storyline planned by the showrunners but his personal choice to pursue political work. The show intentionally left the reasons for Kutner's suicide unexplained, reflecting the complex and sometimes unsolvable nature of Dr. House's medical mysteries. Kal Penn later returned to acting after his White House stint and briefly appeared again in the series finale of House MD.
