Ronan Farrow had a good nighttime chat with George Clooney at the White House Correspondents’ Dinner last weekend. Farrow, a Rhodes Scholar, told us at the Greater Talent Network Speakers Bureau’s 30th anniversary party Wednesday night that a highlight of the DC gala was, “talking about energy policy with George at 2 a.m. in a corner of the Vanity Fair after-party.” Farrow, 25, and his mother, Mia Farrow, worked the room at the United Nations among Michael Moore, Meghan McCain, Gen. Wesley Clark, Tom Wolfe, Danny Glover, Harold Ford, Jr. GTN founder Don Epstein and a late-arriving Newark Mayor Cory Booker, who bear-hugged several guests as he walked into the event.
