(CNN) – Senators Joe Lieberman, John McCain and Lindsey Graham discussed the definition of marriage Tuesday in an interview on "Piers Morgan Tonight," insisting the decision to allow same-sex couples to legally wed should be left up to the states.
"In my state, we're not going to change the traditional definition of marriage and I would support the traditional definition of marriage not out of hate but that I believe that's just best for society," said Graham, a Republican from South Carolina. "At the end of the day states will come out differently on this issue and I think that's the way it should be."

Reiterating that the decision should be left to the states, Lieberman, an independent from Connecticut, added that it's up to the Supreme Court to answer that question as it plans to hear two constitutional challenges to state and federal laws dealing with the recognition of gay and lesbian couples to legally wed.
The courts decision to take up the case comes weeks after voters approved same-sex marriage in three states: Maryland, Washington, and Maine, adding to the six states and the District of Columbia that already have already done so.
