Vice President Joe Biden is set to deliver the keynote address at the Human Rights Campaign's annual dinner next month.
Biden will be speaking to an influential group of gay and lesbian activists who were among President Barack Obama's most loyal supporters during the 2012 campaign.
He will headline the Oct. 5 event with 3,400 people at the Washington Convention Center. HRC is the nation's largest lesbian, gay, bisexual and transgender civil rights group.
The vice president has built strong support within the LGBT community and was credited with pushing Obama to support same-sex marriage.
Biden is considered a potential 2016 presidential candidate. Former Secretary of State Hillary Rodham Clinton remains the leading contender among Democrats if she runs again.
