We know his official title is Associate Director, White House Office of Public Engagement. But what exactly is he doing there?
The word in American Desi circles is that Penn will be serving as the administration's link with the Asian American and Pacific Islander community in an effort to encourage participation in President Obama's ambitious United We Serve plan. United We Serve is a call to service challenging Americans to engage in 'sustained, meaningful' community service.
He recently sent out a mass e-mail to leaders in the community, intimating the same. And then last week he reportedly hosted a conference call to present the campaign to Indian-American and other Asian community leaders. One report said he performed 'quite professionally'.
Wow, Penn really seems to be proving the doubters wrong. There was a lot of speculation that, as a celebrity, that too a goofy one known for starring in marijuana-fuelled films, Penn was going to serve as little more than a figurehead.
But judging by the serious with which he's approached these initial few weeks at work, that's not the case.
