Here's more information from the AP (as of 2:10 p.m.):
"The measure passed 32-24 Wednesday. It now goes to Gov. Pat Quinn, a strong supporter.
Civil unions would give gay couples many of the same rights as marriage - for instance, the power to make medical decisions for a seriously ill partner.
Critics say this would amount to same-sex marriage under a different name.
Some senators argued the Legislature shouldn't be discussing civil unions when Illinois faces a massive budget deficit that should get lawmakers' full attention."
The bill is SB1716.
