Gov. J.B. Pritzker plans to sign a bill on Thursday that would give the state more oversight over Illinois gun dealers, after Democrats kept the paperwork off former Republican Gov. Bruce Rauner’s desk in order to avoid a veto during his administration’s final days, according to a state lawmaker.

The proposal would require firearm stores to get state licenses, a move that supporters contend could reduce gun violence because federal regulators are stretched too thin to adequately handle all the shops operating in Illinois.

Pritzker is set to sign it into law at Young Elementary School on Thursday morning, according to Democratic state Sen. Don Harmon of Oak Park, the proposal’s sponsor. Lawmakers approved it last year in the wake of the killing of Chicago police Cmdr. Paul Bauer and the high school shooting in Parkland, Fla.

“This is a commonsense piece of legislation, so when I introduced it a decade and a half ago, I thought we would be celebrating this day much sooner,” Harmon said. “But important causes are worth fighting for, and I am proud to stand with the countless advocates and supporters who have stuck with us for all these years.”
