CHICAGO (AP) — Lawmakers returning to Springfield this week will address a proposal to let illegal immigrants obtain driver's licenses and could tackle medical marijuana, state facility closures and tax disclosure for Illinois corporations.

But on most major issues lawmakers are simply laying the groundwork for the first week of January and what's shaping up to be another blockbuster lame duck session.

That's when lawmakers in their last days in office could get the chance to vote on deals to expand gambling, fix the state's pension crisis and allow same-sex marriage.
