Author Robert Caro is cautiously optimistic about being Conan O Brien’s friend.

Robert and Conan discuss his biographical works on Robert Moses and Lyndon Johnson, getting into the shoes of his subjects, his new book “Working,” searching for the man who helped steal a Senate election, and the parallels we can draw to today’s events. Plus, Conan responds to a listener voicemail about the size of his skull.
