Iowa State Representatives Tom Shaw, Glen Massie and Kim Pearson say they'll attempt to impeach four Supreme Court justices who favored gay marriage, the Iowa Independent reported.

The action comes after voters on November 2 ousted three out of the seven judges whose unanimous 2009 ruling brought gay marriage to the Midwest. Democrats in control of both houses have refused to back a constitutional amendment banning gay marriage, frustrating social conservatives opposed to the institution.

Opponents, led by former GOP gubernatorial candidate Bob Vander Plaats, turned their attention to ousting the three judges up for a retention vote.

Republicans also managed to wrest control of the House and the governor's mansion away from Democrats.

The three GOP lawmakers say they will draft articles of impeachment to try to remove the remaining four judges because they've heard from voters angry about the gay marriage ruling.

Impeachment would require the assistance of the Senate, which remains in the hands of Democrats.

A spokesman for the American Civil Liberties Union of Iowa, Ben Stone, called the GOP push for impeachment “truly shocking.”
