Obama4-21-11.jpg10:41 AM: President Obama has left the Bay Area after a whirlwind visit that included a town hall meeting at Facebook headquarters and two appearances at fundraisers in San Francisco.

Air Force One took off from San Francisco International Airport at 10:36 a.m.

He is now headed to Reno, Nev.

10:32 AM: President Obama has arrived at San Francisco International Airport and is about to depart on Air Force One.

At 10:23 a.m., a black limousine pulled up to the aircraft and Obama exited the car, jogged up the stairs to Air Force One and smiled and waved before disappearing inside.

9:46 AM: San Francisco police are advising drivers to steer clear of the South of Market area near Moscone Center, where streets are being closed this morning because of President Obama’s visit.

The president was scheduled to attend a breakfast fundraiser this morning at the St. Regis Hotel, located near Mission and Third streets.

He will fly out of San Francisco International Airport on Air Force One later this morning.

Police spokesman Officer Albie Esparza said there will be rolling street closures in SOMA sometime around 10:30 a.m. to make way for the president’s motorcade as he heads to the airport.

“The best advice for motorists is to stay away from there,” Esparza said.
