Michigan Gov. Gretchen Whitmer will call on state lawmakers this week to pass legislation proactively protecting key provisions in the Affordable Care Act, including no-cost preventive services, as the nation’s health law continues to face legal challenges in federal court.

Whitmer, who is in her second term and working for the first time with a Legislature under complete Democratic control, will call for a plan to codify the Affordable Care Act during a speech Wednesday where she will outline her legislative priorities for the second half of the year.

It comes as one of the Affordable Care Act’s most popular provisions that requires insurers to cover preventive services faces a threat in federal court.
