LGBT activists, advocates and community members have begun filtering into the capitol as a the deciding vote on Illinois marriage equality is expected as early as this afternoon.
Sponsors have until Friday to pass the Religious Freedom and Marriage Fairness Act, which would grant equal marriage rights to same-sex couples.

Advocates with Equality Illinois, Lambda Legal, the American Civil Liberties Union of Illinois, The Civil Rights Agenda, Human Rights Campaign, Gay Liberation Network and other groups are already in the capitol. Sources say that the families of some reps. are also headed for Springfield.
Anti-LGBT groups not appear to be present.
The bill has already passed the Senate and Gov. Pat Quinn has vowed to sign it.
The bill has the backing from major political players including President Obama, who expressed support for the measure in Chicago this week.
"Here in Illinois, we've got a vote on same-sex marriage that's going to be coming up in the Legislature," he said, according to the Chicago Sun-Times. "I just want to say for the record it's something that I deeply support."
Windy City Times will continue to update with details from Springfield.
