Seven months before he publicly supported same-sex marriage, Obama told ABC News' George Stephanopoulos that he was "still working on" considering a move from supporting civil unions for same-sex couples to backing same-sex marriage.
"I'm still working on it," Obama said in 2011. "I probably won't make news right now, George. But I think that there's no doubt that as I see friends, families, children of gay couples who are thriving, you know, that has an impact on how I think about these issues."
The president cited those same friends and families when he publicly announced his support for gay marriage last year, telling Roberts that he believes people will become more comfortable with the idea in the years to come.
"I have to tell you that over the course of several years as I have talked to friends and family and neighbors, when I think about members of my own staff who are in incredibly committed monogamous relationships, same-sex relationships, who are raising kids together; when I think about those soldiers or airmen or marines or sailors who are out there fighting on my behalf and yet feel constrained, even now that 'don't ask, don't tell' is gone, because they are not able to commit themselves in a marriage, at a certain point I've just concluded that for me, personally, it is important for me to go ahead and affirm that I think same-sex couples should be able to get married," Obama said.
