Obama was in Los Angeles Monday for fundraisers for Boxer and the Democratic National Committee. The three events were expected to raise close to $3.5 million. During his speech to the early evening reception at the California Science Center Obama was heckled by gay rights protesters. 

"What about don't ask, don't tell?" one protester shouted. Obama yelled back "we are going to do that."

The president can likely expect another mixed reception when he goes to San Francisco. During a fundraising trip there last October, protesters gathered outside the Westin St. Frances Hotel where he spoke.

The San Franscisco event will raise money for Boxer and the Democratic Senatorial Campaign Committee. The Boxer campaign did not specify the date of the trip.

Boxer faces a tough reelection campaign. There are three Republicans vying for the chance to face her and polls show she's in a tight race with whoever the nominee will be.
