Perhaps the president won’t be golfing after all. The White House is expected to announce today that President Obama will be attending the annual HRC dinner in Washington, DC on Saturday evening, the day prior to the National Equality March.

Mr. Obama’s appearance on Saturday at the annual dinner for the Human Rights Campaign, a leading gay rights advocacy group, represents a significant show of support for gay rights at a time when many prominent gay and lesbian activists have been questioning the president’s commitment to their issues.

Many gay rights activists have become increasingly vocal about their frustration over what they see as tepid support from Mr. Obama. While the president has professed support for overturning the ban on gays in the military and called the law that precludes federal recognition of same-sex marriages discriminatory, he has not engaged on gay rights issues as actively as some had hoped.

The Justice Department is defending the federal marriage law, known as Defense of Marriage Act, much to the dismay of many gay rights advocates. And Mr. Obama has been noncommittal about when he will move to end the “don’t ask don’t tell” policy. In June, he acknowledged their irritations at the slow pace of change at a gathering of about 250 gay rights leaders who had been invited to the White House.

While it remains to be seen what Mr. Obama’s appearance at the dinner will do to his standing in the eyes of gay rights activists, his speech may mollify some of their concerns.

His appearance will mark only the second time a sitting president has spoken to the Human Rights Campaign. The first time was in 1997 when Bill Clinton spoke to the group. That was the first time a sitting president had ever addressed a gay rights organization.
