Democratic presidential candidate Hillary Rodham Clinton said Sunday that she was thrilled with the Supreme Court's summer ruling striking down gay marriage bans in all 50 states.

After NBC's Meet the Press played a montage of Clinton clips in which she appeared to change her positions on several issues, host Chuck Todd asked: “How do you respond to some critics who say, you know, 'Your positions have changed out of political expediency?' That you're sort of whatever the majority is at that time, that's the position you have.”

“Well, I just don't think that reflects either my assessment of issues, and I don't think it reflects how people who are thoughtful actually conduct their lives. I mean, if we don't learn, if we don't, you know, make decisions based on the best information we have available, well, you know, that's regrettable,” Clinton responded.

“On sames-sex marriage, like a lot of people, including our president, I did evolve,” she continued. “And I was not raised to even imagine this. And I'm thrilled now that it is the law of the land. And I have a lot of close friends who are now able to be married because of the changes we've made legally and constitutionally.”

Clinton endorsed marriage equality in 2013 after she had left her post at the State Department.
