President Barack Obama heads to the West Coast on Wednesday to attend a gay fundraiser in Beverly Hills which will include a performance by Glee co-star Darren Criss and the speakers will include talk show host Ellen DeGeneres.

It is the third LGBT-organized fundraiser for Obama this year. An event organized in April by the Obama for America LGBT Leadership Council held in Florida raised $125,000 from 50 supporters. And shortly after he announced his support for gay marriage, the president attended an event in New York hosted by singer Ricky Martin, the Futuro Fund and the LGBT Leadership Council where he raised an estimated $1 million.

More than 600 people are expected to attend tonight's LGBT Leadership Council Gala. Tickets start at $1,250 per person.

CNN reported that a significant portion of Obama's campaign cash is coming from the gay community. The network reported that LGBT “bundlers” – the men and women who have pledged to raise money for the president – have raised at least $8 million for the president in the first quarter of this year.

Richard Socarides, a former adviser on gay rights to President Bill Clinton, told CBS News that financial support from the gay community is “substantial.”

“Because people don't identify their sexual orientation when they give, it's hard to make a mathematical calculation. But I do think it's fair to say that especially given the relative softness from some of the other communities that supported the president in 2008 – I'm thinking specifically of Wall Street – that I think the president and the Democratic Party in general is looking to receive substantial backing from donors who are motivated by gay rights and human rights issues.”

“It's a significant donor group in the Democratic community,” said Steve Elmendorf, a Democratic lobbyist and strategist.

After tonight's gala, the president will attend a fundraiser at the home of Glee creator Ryan Murphy, who is openly gay.
