President Obama heads to New York City Thursday evening to host a gala with the Lesbian, Gay, Bisexual and Transgender (LGBT) community, as advocates are frustrated he hasn't endorsed gay marriage and New York state takes up a key vote on the issue. Obama will headline a $1,250 per ticket event that will also include remarks from actor Neil Patrick Harris. More than 500 people are expected to attend and money raised will go to a joint fundraising committee that contributes to both the Democratic National Committee (DNC) and Obama for America (OFA).
