Updated 12:31 p.m. with use of amendatory veto.
Gov. Pat Quinn has proposed a statewide ban on assault weapons.
The Democrat used his amendatory veto power today to include the ban in a bill related to ammunition sales. It's now up to lawmakers to accept his changes or reject them.
In a letter to members of the General Assembly, Quinn says the ban will make Illinois a safer place to live.
The proposal also calls for a ban on high-capacity ammunition magazines. It was first reported by The Associated Press.
