Quinn signed the measure into law on the same desk that Abraham Lincoln used to write his first inaugural address.
“We are the Land of Lincoln and we understand how important Abraham Lincoln’s words and legacy are important to us,” the governor said, referencing the Emancipation Proclamation. “We understand in our state is part of our unfinished business is to help other states in the United States of America achieve marriage equality.”
Gay state Rep. Greg Harris (D-Chicago) and state Sen. Heather Steans (D-Chicago), who co-sponsored the measure in the Illinois Legislature, joined Quinn on stage alongside Chicago Mayor Rahm Emanuel and other local and statewide elected officials.
“Today we’re here to celebrate family, commitment, equality, love, courage and community,” Harris said.
“Today Illinois makes history by recognizing all committed loving relationships,” Steans added. “Today we welcome all families in Illinois as equally valued.”
Lieutenant Gov. Sheila Simon described herself as a “proud Illinoisan.”
“It’s time to stop planning rallies and start planning weddings,” she said.

Peter LaBarbera, president of Americans for Truth About Homosexuality, held a banner outside the signing ceremony that read “homosexual ‘marriage’: against nature and nature’s God.”
