President Barack Obama appeared on ABC News this afternoon to make a historic declaration: “I think same sex couples should be able to get married.”

The statement echoed loudly across traditional and social media. Within minutes (perhaps seconds) of the president’s statement, “Same-Sex Marriage Should” and “Mr. President” became trending topics on Twitter.  “ABC’s Robin Roberts,” the journalist who conducted the interview with Obama, also became a trending topic.

Several more topics related to the interview started trending, among them #MarriageEquality and Log Cabin Republicans.

During the interview with Roberts, Obama said:

"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.”

According to a tweet from The Daily Beast, Mitt Romney told reporters he opposes same-sex marriage and supports a constitutional amendment banning it.
