3 things we learned from @mariannealeardi's interview with @jaketapper or the @katzjcc: 1. Jake Tapper lowkey wrote a Frank Sinatra song for his new novel, "The Devil May Dance." 2. He's got some pretty heated opinions on conspiracy theories. 3. Once a junior staffer told him he needed to "up his sock game." (And he totally did.) Photos: @dmhphotographer
