White House Press Sec being grilled by reporters over Biden's endorse of gay marriage

The straight press, as it were, won't let up on White House press secretary Jay Carney over Vice President Biden's embrace of gay marriage yesterday. Carney pretty much has nothing to say, other than listing all the good things the President has done for gay and trans people. And that's nice, and doesn't answer the question as to why the President disagrees with the Vice President on marriage.
