Today, in an interview with Robin Roberts of ABC News, President Barack Obama made his position on gay marriage very clear: “I think same-sex couples should be able to get married.

“You know when I go to college campuses, sometimes I talk to college Republicans who think that I have terrible policies on the economy, on foreign policy, but are very clear that when it comes to same-sex equality or, you know, sexual orientation, that they believe in equality. They are much more comfortable with it. You know, Malia and Sasha, they have friends whose parents are same-sex couples. There have been times where Michelle and I have been sitting around the dinner table and we’re talking about their friends and their parents and Malia and Sasha, it wouldn’t dawn on them that somehow their friends’ parents would be treated differently. It doesn’t make sense to them and, frankly, that’s the kind of thing that prompts a change in perspective.”

Excerpts of the interview will air tonight on “World News With Diane Sawyer,” as well as tomorrow morning on GMA. ABC’s “Good Morning America” Thursday. Watch the clip from the interview below where Obama explains his position and the evolution of his stance on this issue.
