Illinois Attorney General Lisa Madigan is headlining a fundraiser for the advocacy group Campaign for Better Health Care in Chicago this evening. While Madigan is expected to discuss her push for consumer protection in a soon-to-be established health exchange program, the AG is also set to address the Affordable Care Act (ACA) as it is gradually implemented in the state.

This comes as the U.S. Court of Appeals for the 11th Circuit in Atlanta heard oral arguments last week in a class action lawsuit against the ACA. The suit, State of Florida v. U.S. Department of Health and Human Services, challenges the constitutionality of the Obama administration's signature health care reform law.

The attorneys general from 26 states, including Arizona, Indiana, Michigan, and Wisconsin, are listed as the plaintiffs. Madigan herself has gotten pressure from Illinois Republicans to join in on the suits, but she said last year she would not try to block the bill.

At the time the suits surfaced, eight Democratic AGs issued a joint release in support of the health care reform law. Progress Illinois previously covered this political dynamic, including Madigan’s public position -- or lack thereof -- on the ACA. Madigan was noticeably absent from the release and at the time, Madigan spokeswoman Natalie Bauer said: "There's a multitude of lawsuits on both sides of this issue. At this point we are actively monitoring the many lawsuits that are proceeding through the legal system.” Asked if Madigan would file a brief in support of the law, Bauer said it depends on how the current legal challenges proceed.

UPDATE 4:57 p.m.: Madigan spokeswoman Maura Possley said the attorney general continues to monitor the legal battles, but could not offer any further details.
