Former U.S. Secretary of State Hillary Clinton came out in support of gay marriage Monday in a video for the Human Rights Campaign.

“A little over a year ago in Geneva, I told the world that gay rights are human rights and human rights are gay rights and that the United States would be a leader in defending those rights,” Clinton begins the video for the HRC’s Americans for Marriage Equality Campaign, which you can view above.

The potential 2016 presidential candidate said some countries “did not want to hear that, but I believe America is at is best when we champion the freedom and dignity of every human being. That’s who we are. It’s in our DNA.”

Clinton said it was her experiences as secretary of state that led her to support gay marriage, both personally and “as a matter of law.

“Now having left public office, I want to share some of what I’ve learned and what I’ve come to believe. For America to continue leading in the world, there is work we must do here at home. That means investing in our people, our economy, our national security. It also means working every day as citizens, as communities, as a country to live up to our highest ideals and continue our long march to a more perfect union,” Clinton says. “LGBT Americans are our colleagues, our teachers, our soldiers, our friends, our loved ones, and they are full and equal citizens and deserve the rights of citizenship. That includes marriage. That’s why I support marriage for lesbians and gay couples.”
