President Barack Obama will deliver the keynote address at the 15th annual Human Rights Campaign (HRC) National Dinner on Saturday, October 1.

HRC, the nation's largest gay rights advocate, announced on Wednesday that the president will address its annual fundraiser at the Washington Convention Center in Washington D.C.

“We are honored to share this night with President Obama who has a tremendous record of accomplishment for LGBT people,” said HRC President Joe Solmonese.

The announcement comes a day after the military officially ended “Don't Ask, Don't Tell,” the policy that banned gay and bisexual troops from serving openly.

“On the heels of the end to 'Don't Ask, Don't Tell.' we look forward to celebrating our victories and redoubling our efforts for the fights that remain ahead,” Solmonese added.

In 2009, Obama attended the event,which draws nearly 3,000 attendees.

Gay rights activists who have called on the president to endorse gay marriage ahead of next year's general election are certain to renew their pleas ahead of the event.
