The White House released a statement from the President reiterating his position:
The sacred institution of marriage should not be redefined by a few activist judges. All Americans have a right to be heard in this debate. I called on the Congress to pass, and to send to the states for ratification, an amendment to our Constitution defining and protecting marriage as a union of a man and a woman as husband and wife. The need for that amendment is still urgent, and I repeat that call today.Here, here.
