The state senate is expected to consider a bill that would expand casino gambling.
It was proposed by State Sen. Terry Link (D-Waukegan), and would add four new casino locations.
A group of religious leaders is staunchly opposed to expanding gambling.
"It will not make money for the state budget," said First United Methodist Church Senior Minister Phil Blackwell. "Gambling's not a growth industry. The gambling proposal is about power."
Casino owners say gaming revenue in the state is flat because the smoking ban is keeping people away.
