Former secretary of state Hillary Clinton has come out in support of gay marriage, making her announcement in a video released by Human Rights Campaign.

"LGBT Americans are our colleagues, our teachers, our soldiers, our friends and our loved ones, and they are full and equal citizens and deserve the rights of citizenship. That includes marriage," she says in a manner-of-fact tone, midway through the six-minute video. "That's why I support marriage for lesbian and gay couples. I support it personally and as a matter of policy and law."
