JUDY WOODRUFF:

A coalition of groups opposing same-sex marriage rallied in Washington today outside the U.S. Capitol, marching to the Supreme Court in support of marriage between one man and one woman.

This comes just days after the Obama administration announced its intent to ban federal contractors from discriminating on the basis of sexual orientation or gender identity, and as polls show the tide of public opinion changing rapidly.

To discuss how the fight over gay rights is playing out both here in Washington and across the country, we are joined by Edward-Isaac Dovere. He's senior White House reporter for Politico. And David Crary, who covers national social issues for the Associated Press.

And welcome to you both.
