Vice President Joe Biden will deliver the keynote address at the Human Rights Campaign's (HRC) 17th annual National Dinner on Saturday, October 5.

“Vice President Biden has been a champion of civil rights for his entire career, from his leadership on the Violence Against Women Act to his strong support for marriage equality,” said Chad Griffin, president of HRC, the nation's largest LGBT rights advocate. “As Senator and Vice President, his work to advance LGBT equality is just one chapter in a remarkable lifetime of service.”

More than 3,400 people are expected to attend the event to be held at the District of Columbia's Washington Convention Center.

Biden, considered a possible 2016 presidential candidate, is credited with pushing President Barack Obama to support marriage equality during the 2012 campaign.
