Republican Sen. Lisa Murkowski of Alaska announced her support in June 2013 for same-sex marriage, becoming the third sitting GOP senator to back the right for gay and lesbian couples to marry. "I support the right of all Americans to marry the person they love and choose because I believe doing so promotes both values: it keeps politicians out of the most private and personal aspects of peoples' lives -- while also encouraging more families to form and more adults to make a lifetime commitment to one another," she wrote in an opinion piece on her website.
Former Maine Sen. Olympia Snowe says her views have shifted on same-sex marriage, and that she no longer supports the Defense of Marriage Act. "I think obviously this has evolved over time on the whole issue for the whole country and the nations," Snowe, a moderate Republican, told CNN. "We've seen a sea change in society's whole attitude on this particular issue and it's only natural for government to be responsive to those changes."

Mark Kirk, who is from Illinois, became the second sitting Republican senator to come out in support of same-sex marriage in a blog post in April 2013, writing, "Our time on this earth is limited, I know that better than most. Life comes down to who you love and who loves you back -- government has no place in the middle." He returned to work a few months before making a statement after taking time off to recover from a stroke.
