After golf and before his statement on Libya, Pres. Obama stopped by the Martha’s Vineyard home of Comcast CEO Brian Roberts. That’s the motorcade, right. Comcast is the majority owner of NBCUniversal. From the pool report, on Politico:

The presidential motorcade on Martha’s Vineyard peeled out of Blue Heron Farms at 5:15 p.m. with the president and Valerie Jarrett in tow. …Obama and Jarrett arrived at West Tisbury home of their friends, Brian and Aileen Roberts, spokesman Josh Earnest informs us. It was 5:30 p.m. Roberts is chairman and CEO of Comcast.
