Either this means the next installment of Harold and Kumar is put on hold or this is a secret plot to do research for the next sequel, Kal Penn is joining the Obama Administration

According to the article:

I've been thinking about [moving into politics] for a while. I love what I do as an actor. I couldn't love it more. But probably from the time I was a kid, I really enjoyed that balance between the arts and public service. I went to a performing arts high school, but I still took a bunch of those dorky political science classes. It's probably because of the value system my grandparents instilled in me. They marched with Gandhi in the Indian independence movement, and that was always in the back of my head. So the past couple of years I thought about it a little more. And in '06 I started this international studies program at Stanford, where they actually let you do most of the course work online. So it was something I could do while I was acting. And I thought this might be the right time to go off and do something else.

After the withdrawal of Sanjay Gupta, another high-profile South Asian in the media, hopefully this one will be smoother sailing.
