The Latest: GOP lawmaker demands proof on Rauner claim

SPRINGFIELD, Ill. (AP) — The Latest on a scrutinized Medicaid overhaul contract (all times local):1:30 p.m.

A Republican lawmaker is challenging Gov. Bruce Rauner over a claim that the Democratic House speaker influenced the cancellation of a $12.5 million no-bid contract the administration signed.

Barrington Hills GOP Rep. David McSweeney says Republican Rauner must provide proof or apologize.

Independent chief procurement officer Ellen Daley nullified the Medicaid-related consulting contract with McKinsey & Co. Tuesday. She says it should have been let for bid.

The Chicago Tribune reported Thursday that Rauner blamed his nemesis. He said Chicago Speaker Michael Madigan has "heavy influence" over Daley.
