Iowa Rep. Steve King said Monday that he wants Congress to weigh in on the recent Supreme Court ruling striking down state bans on gay marriage in all 50 states.

King, vocal opponent of LGBT rights, told The Washington Post that he's working on a nonbinding resolution of disapproval against the decision.

“I think it's important to let the public know where they stand,” said King, a Republican.

“What I reject is an activist court with no basis for this decision transforming the greatest civilization we've ever seen by a 5-4 decision,” he added.

King also criticized Justices Elena Kagan and Ruth Bader Ginsburg for taking part in the case because both had presided over the marriages of same-sex couples. Ginsburg has united five such couples, the most of any current or retired justice.

If the two justices had recused themselves, “it would have been a 4-to-3 decision the other way,” King said.
