National and state firearms groups are fighting back against a pair of sweeping and controversial gun control bills being pushed through the Illinois state legislature during the final days of a lame-duck session.

On Wednesday night, a state Senate committee advanced two measures to restrict semiautomatic weapons and high-capacity magazines. It’s unclear at this point whether the full Senate will take them up before the new General Assembly class is sworn in Jan. 9, when the process would have to restart.

The bills would face an uphill climb in the Senate, particularly as gun groups were mounting a flash campaign against them. was told late Thursday that Democrats were still trying to line up the votes, after the measures passed on party lines out of committee the night before.

The first proposal would ban the possession, delivery, sale and transfer of semiautomatic handguns and rifles. Gun groups say this kind of restriction would be so expansive as to affect most gun owners in the state.
