Illinois House members gave bipartisan support Wednesday to consolidating downstate police and fire pension systems, a top priority of Gov. J.B. Pritzker. The House voted 96-14 to approve the consolidation that is touted as a way to improve investment returns of the systems and ease pressure on local property taxes. The bill must still be approved in the Senate by Thursday, the last scheduled day of this year’s veto session. The bill won overwhelming support in the House after negotiators agreed to remove a last-minute addition that threatened to derail the proposal on Tuesday. The addition cause the Illinois Municipal League — which has pressed for the consolidation for years — to suddenly drop its support. After the compromise was reached, the IML said it again supported the idea.
