Update: Obama Arrives at SFO

President Obama has arrived in the Bay Area for a series of fundraising events in San Francisco for his 2012 re-election campaign.

Air Force One touched down at San Francisco International Airport at 12:39 p.m. The president's first stop will be at a private reception at the Mark Hopkins Intercontinental Hotel on Nob Hill at 2 p.m.

Obama will then head to a private fundraising dinner at a Pacific Heights home, and then give a speech at an 8 p.m. fundraiser at the Nob Hill Masonic Center featuring a performance by Soundgarden frontman Chris Cornell.

Among those in attendance at tonight's event will be 15 excited teenagers from the Boys & Girls Clubs of San Francisco, spokeswoman Brittany Johnson said.

The 15-, 16-, and 17-year-olds were selected to see the president based on their achievements in school and leadership roles they have taken on in the community, Johnson said.

"They're absolutely thrilled," Johnson said.

Several activist groups plan to protest Obama's visit.

"Frostpaw," a polar bear mascot for the environmental protection group Center for Biological Diversity, will appear outside the Masonic Center to call on the Obama administration to halt oil drilling in the Arctic.

Medical marijuana activists also plan to gather outside the Masonic Center as part of a nationwide day of protest against the administration's crackdown on marijuana dispensaries, organizers said.

Activists from CodePink, World Can't Wait SF, and the Occupy movement have also indicated they will protest outside that event. Obama is scheduled to spend the night in San Francisco tonight before departing for Washington state Friday morning. His visit to San Francisco follows fundraising stops in Los Angeles.
