For the first time in history, a sitting U.S. President has supported same-sex marriage. In an interview with ABC News, President Barack Obama told Robin Roberts, "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 once opposed same-sex marriage but claims his views on the issue were "evolving."

It should be noted that this announcement comes on the heels of Vice President Joe Biden saying this past Sunday on NBC that he was "absolutely comfortable" with couples of the same gender getting married.

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.

This puts President Obama head to head with presumptive Republican presidential nominee Mitt Romney on an issue of same-sex marriage. Regardless of Americans being evenly split on the issue, I think everyone can agree that today's announcement from President Barack Obama was indeed a historical one.
