Democratic presidential front-runner Hillary Rodham Clinton and Vice President Joe Biden, who is contemplating his own White House run, over the weekend reaffirmed their support for LGBT rights.

Biden headlined the Human Rights Campaign's (HRC) 19th annual National Dinner in Washington, D.C., while Clinton addressed the group earlier in the day.

“Transgender people are valued, they are loved, they are us,” Clinton told the crowd.

She pledged to work to reduce violence against transgender people and called on the Pentagon to end its policy banning transgender service in the armed forces.

“Having the world's strongest military doesn't just mean having the best-trained forces or the biggest arsenal,” she said. “It means, being a leader on issues like this.”

Biden also called for an end to the ban, calling transgender rights “the civil rights issue of our time.”
