MADISON, Wis. -

Gov. Scott Walker says he continues to meet with lawmakers to try and reach a compromise on his proposal to expand private school vouchers in Wisconsin.

The Legislature's budget-writing Joint Finance Committee was scheduled to vote on the proposal on Wednesday. But as of mid-day Tuesday, no deal had been reached.

Walker told reporters in Milwaukee that he thinks a deal will be reached this week, but maybe not by Wednesday. Walker says he does not expect to get exactly what he wants.

Walker's plan would expand vouchers initially to nine more school districts across the state, with the trigger being how well schools perform on new state report cards.

Critics say the report cards weren't meant to be used that way.
