The HRC cast its endorsement of Clinton as an effort to lock in "all the progress we've made" under President Obama, mentioning the repeal of the military's "don't ask, don't tell" policy and the push to legalize gay marriage across the country.

Clinton addressed HRC during a speech in October after it was reported that she turned down an evening keynote opportunity to appear on "Saturday Night Live."

During her fall address, Clinton pitched herself as a longtime ally of the group and promised "from one HRC to another" to fight alongside the group.

She also called on Congress to pass a federal Equality Act and focus on international gay rights concerns.

Clinton has made gay rights advocacy a major part of her 2016 bid, starting by showing a gay couple in her campaign launch video last year.
