And for his part, Branstad isn't commenting:
"This is a separate branch of government and I've got enough on my plate not to get into that one," Branstad says. "So I don't intend to comment on it."
Previously, Branstad had called upon the legislature to vote on a constitutional amendment to ban same sex marriage, which if passed in the legislature would then go to the voters. However, the Democrats have retained a narrow majority in the state Senate, and the majority leader has said he would not hold the vote.
Of that topic, Branstad has said:
"Just because you're a leader in the Legislature doesn't mean you're a dictator where you have the right to make a unilateral decision, I think, on an issue of this importance and magnitude," Branstad said. "Certainly the senators should be given an opportunity to vote on this."
