The first of two days of oral arguments over what supporters call marriage equality brings the boldest of the claims that gay rights activists will make ““ that there is a constitutional right to same-sex marriage that states may not deny. [Washington Post]

TODAY IS the day same-sex marriage will be argued at the Supreme Court. It is a historic moment for America.

The Senate is coming around one by one, at least Democratic members are and on Monday, Senator Mark Warner made his statement on Facebook.

I support marriage equality because it is the fair and right thing to do. Like many Virginians and Americans, my views on gay marriage have evolved, and this is the inevitable extension of my efforts to promote equality and opportunity for everyone. I was proud to be the first Virginia governor to extend anti-discrimination protections to LGBT state workers. In 2010, I supported an end to the military’s “˜don’t ask, don’t tell’ policy, and earlier this month I signed an amicus brief urging the repeal of DOMA. I believe we should continue working to expand equal rights and opportunities for all Americans. – Mark Warner, Facebook

Alaska’s Senator Mark Begich joined Warner, but also Senator Claire McCaskill in supporting the right for same sex couples to marry.
