Illinois Sen. Heather Steans, D-Springfield, introduced the Equal Marriage Act last week.
The bill would legalize marriage between two adults of the same sex.
State Rep. David Reis is working on getting a constitutional amendment before voters that would define marriage as the union between one man and one woman.
"If we're going to continue to get pushed from the Left, we're going to have to put this measure into the state constitution so we can protect this fundamental value," Reis said.
The bill has not received a committee assignment yet.
