The Illinois Senate has canceled a session scheduled for Friday and has adjourned.

Senate President John Cullerton told senators to be prepared to return Tuesday in case action is needed after a House session.

The House is scheduled to work Sunday through Wednesday, the final day of the current General Assembly.

Expectations were high that Cullerton's Democrats would approve a gay marriage bill. A committee OK'd the measure Thursday, but backers are uncertain when they'll call it for a floor vote after the proposal hit several unexpected snags.

Another Senate committee approved curbs on assault weapons and high-capacity ammunition magazines, but those bills haven't yet moved to the floor for action.

Democratic Gov. Pat Quinn says the Legislature must reform the underfunded state pension systems before finishing Wednesday.
