The U.S. Supreme Court agreed on Friday to decide the legality of a key component of the Affordable Care Act that effectively gives a task force established under the landmark healthcare law known as Obamacare the ability to require that insurers cover preventive medical care services at no cost to patients.

At issue is a provision requiring health-care plans to cover no-cost preventive care, including cancer screenings, immunizations and contraception. A Christian-owned business has challenged it.

The Supreme Court said Friday it will review the constitutionality of the Affordable Care Act’s no-cost coverage mandates for certain preventive care services, putting the landmark health care law in front of the justices again just as President-elect Donald Trump – who tried to repeal the law during his first presidency – returns to the White House.
