It was "a basic street robbery" and no one was hurt, according to an anonymous D.C. official who spoke to The Washington Post.
Penn was approached by a gunman around 1:30 a.m. near 15th and S streets in the Dupont Circle area, reports The Post. His wallet was stolen, among other belongings.
The actor began a stint at the White House last July, as associate director of public engagement. He's served as a liaison facilitating relationships between
President Obama and the Asian-American, and Pacific Islander
communities, as well as arts groups, Penn told The Huffington Post.
According to Entertainment Weekly, Penn is preparing to leave that White House position.
