First lady Michelle Obama has appeared at a presidential campaign reception at San Francisco's California Academy of Sciences.
San Francisco Chronicle reporter Joe Garofoli, the pool reporter for Friday night's event, says the first lady was introduced by California Attorney General Kamala Harris, an early supporter of President Obama in 2008.
About 350 people attended the event, called "Families for Obama," General admission tickets started at $500, and the event was expected to raise at least $175,000 for the Obama campaign.
On Saturday, the first lady is scheduled to head to nearby Alameda to join the commissioning ceremony for the Coast Guard Cutter Stratton. It is named after the director of the Coast Guard Women's Reserve during World War II.
Saturday's ceremony marks the formal introduction of the vessel to the Coast Guard's active fleet.
