In a bold confirmation heading into the November election, President Barack Obama officially affirmed his support for gay marriage Wednesday.
During an exclusive interview with ABC News' Robin Roberts to air Thursday, Obama said he's now fully "evolved" to support the legalization of same-sex marriage -- the first president to take that position.
"When I think of members of my own staff who are in incredibly committed, monogamous same-sex relationships who are raising kids together," Obama explained, "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're 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," he concluded.
President Obama's reversal comes just days after members of his administration also expressed their support for gay marriage -- putting pressure on him to voice his stance.
Earlier this week, Vice President Joe Biden said he was "absolutely comfortable" with equal rights for married gay couples.
Education Secretary Arne Duncan also voiced his support of same-sex marriage to MSNBC. And later, White House Press Secretary Jay Carney touted Obama's record of "extremely aggressive" support for gay rights.
Tuesday, Obama's campaign said the president was "disappointed" in North Carolina's recent decision to pass an amendment, barring gay marriage.
About a year-and-a-half ago, President Obama said he was against gay marriage, but in support of "strong civil unions."
