As the president continues his California tour, which will take him as far as San Diego, expect traffic to take a hit, notably from 9 a.m. to 11 a.m. in the area around Santa Monica Boulevard and Avenue of the Stars.
Obama's motorcade Wednesday generated some complaints along with the throngs of people lining the route to wave and catch glimpse of the president.
Some drivers took to to Twitter using an #ObamaJam hashtag to voice their frustrations as the motorcade wound its way toward Bel-Air along Beverly Glen Boulevard during the evening commute.
At the ceremony at USC, comedian Conan O'Brien seized on the ObamaJam chatter during his warm-up act to rib the president over his impact on L.A.'s streets.
"What the hell? I know you left Washington six hours ago, but I left Burbank seven hours ago," he said.
"There are two things that make traffic shut down in this town," O'Brien continued, "a visit from the president and a light drizzle."
