Iowa House Republicans will attempt to bring about a vote on a constitutional amendment banning gay marriage on Monday, the Iowa Independent reported.

The paper is reporting that gay rights group One Iowa believes Republicans will attempt to fish a bill that seeks to define marriage as a heterosexual union in the Iowa Constitution out of committee and put it up for a floor vote. Committee members have not acted on Democratic state Representative Michael Reasoner's proposed bill that aims to overturn the Iowa Supreme Court's April 3, 2009 ruling legalizing gay marriage.

“While legislative leadership has stood firm in support of equality, extremists are attempting to overthrow House rules and push an anti-marriage amendment to the floor!” One Iowa said in an email alert.

The procedural move to pull a bill out of committee requires a 51 vote majority. Seven Democrats would have to cross the aisle and vote with Republicans for the procedure to succeed. At least one Democrat, Reasoner, is expected to do that.

Last year, Republicans made several attempts to bring a similar measure to the floor. Democratic leaders, however, managed to block the efforts.
