A letter signed by 23 Democrats — including Senate President John Cullerton — went to Quinn Thursday and was obtained by The Associated Press.
The letter notes that authorities in at least eight counties are already refusing to prosecute those who carry concealed weapons.
It asks the Democratic governor to “make your intentions known” on concealed carry legislation awaiting action because of a July 9 federal court deadline to implement a plan.
With a veto and no time for legislative response, the senators fear crisis and confusion.
Aides say Quinn is carefully reviewing the legislation.
