President Barack Obama left the San Fernando Valley on Wednesday afternoon following an overnight stay and an appearance on a TV talk show. The president had arrived at Los Angeles International Airport on Tuesday and headed to Burbank to tape “The Tonight Show with Jay Leno.” It was the president’s fourth appearance on the show since taking office. Following his TV taping, Obama flew by helicopter to Van Nuys Airport and then traveled by presidential motorcade on the Ventura Freeway to Woodland Hills, where he stayed overnight at the Hilton hotel. A media report stated Obama dined in his hotel room with DreamWorks Animation Chief Executive Jeffrey Katzenberg, a large Democratic donor. Security for the presidential visit included the closure of Canoga Avenue between Victory Boulevard and Erwin Street, with extra police and a security detail around the Warner Center area, according to the Topanga Community police station. Traffic backed up in the area. On Wednesday, Obama held a live-streaming conference online to talk about his housing agenda. Later he headed south to meet with troops at Camp Pendleton in San Diego County.
