Hundreds of opponents and supporters of the Iowa Supreme Court's Varnum v. Brien decision legalizing same-sex marriage descended Thursday on the Iowa Capitol and watched as House Speaker Pat Murphy declined twice to call up a constitutional amendment defining marriage as a legal union between a man and a woman.

"Let us vote! Let us vote! Let us vote!" supporters of the Iowa Marriage Amendment shouted after the first attempt to bring the issue to the House floor was ruled out of order.

Advocates on both sides of the issue watched at about 9:30 a.m. as House Minority Leader Kraig Paulsen made an attempt to bring House Joint Resolution 6 to the House floor.
