George Clooney: making the Senate Foreign Relations committee a little sexier. (DAN STEINBERG/AP)

Last time the actor, who has long championed Sudan, was in Washington, he got the full VIP treatment: meetings with the likes of President Obama and then-House Speaker Nancy Pelosi, and a pack of cameras following his every move.

This time, he’ll be telling the Senate Foreign Relations committee about his work with the Satellite Sentinel Project, an organization he founded with human-rights activist John Prendergast.

The project uses satellite images to monitor southern Sudan to deter violence by leaders there—a kind of “antigenocide paparazzi,” in Clooney’s words.

Which is something the oft-snapped actor would know a lot about.
