Rep. Jared Polis (D-Colo.) stepped up his feud against Rep. Steve King (R-Iowa) by proposing a bill that would ban him from legislating entirely. 

His office announced the “Restrain Steve King from Legislating Act” in a statement Friday afternoon that bashed King for his own “Restrain the Judges on Marriage Act,” which King revealed on Wednesday. King’s bill aims to take marriage cases out of the jurisdiction of federal courts in favor of states, a move prompted by next week’s Supreme Court oral arguments on gay marriage cases.

“For too long, Steve King has overstepped his constitutionally nonexistent judicial authority,” Polis said in the statement.
