In an interview with CNN on Friday, Snowe said she no longer supports the Defense of Marriage Act, which defines marriage as between a man and a woman. Snowe also said she supports a law passed by her state's legislature that legalizes same-sex marriage, according to CNN.
Snowe's shift follows announcements by a number of senators that they now support same-sex marriage. Snowe said there has been a "sea change in society's whole attitude" on same-sex marriage and that government should be "responsive to those changes."
"The time has come," Snowe told CNN. "I think what we're seeing is, I think, changing societal conventions, that ultimately you see the transformation of society's gradual thinking and evolving on issues. I think we're seeing those sea changes on this particular question."
