Déjà vu: Ben Affleck brings George Clooney’s adviser to Capitol Hill

But that’s not the only similarity between Affleck’s visit and Clooney’s. 

The other link is John Prendergast, an expert on African conflicts and co-founder of the Enough Project.

Prendergast will be sitting next to Affleck on Tuesday in the hearing room, and he’ll likely assist the actor in navigating the halls of Congress before and after the actual hearing. 

It was announced Monday that Affleck and Prendergast will be joined at the hearing by Cindy McCain, the wife of Sen.

For those hoping for a glimpse of the hunky actor (or for those who’d prefer to avoid the media frenzy), Affleck will address a House Foreign Affairs subcommittee in Rayburn House Office Building Room 2172 at 1 p.m.
