SPRINGFIELD, Ill. (AP) -- Black lawmakers undecided on gay marriage are feeling increasing pressure as a vote nears, but are keeping mum on their plans.
Few members of the House Black Caucus have publicly backed the measure, which would make Illinois the 13th state to allow same-sex marriage.
Caucus members are being lobbied extensively by both sides. Their support is seen as key.
Rep. Will Davis of Chicago, who is undecided, urged advocates to "look to the Republican side."
Chicago Rep. Emanuel Welch said Wednesday he was "leaning yes," but would not commit to a vote until it is called.
The bill's sponsor, Chicago Rep. Greg Harris, says a vote is expected before Friday.
The Senate passed gay marriage in February. Gov. Pat Quinn supports the measure and describes it as a priority.
