Hobby Lobby Stores is asking the U.S. Supreme Court to block part of the federal health care law that requires it to provide insurance coverage for the morning-after pill and similar emergency contraception pills.

The arts-and-crafts company is owned by a conservative Christian family. They argue the drugs are tantamount to abortion because they can prevent a fertilized egg from implanting in a woman's womb.

Oklahoma-based Hobby Lobby asked the high court for an injunction Friday, a day after a federal appeals court rejected the company's request. A U.S. District judge turned down the company last month.

Hobby Lobby is the largest private employer suing over the mandate. Not providing the drugs will subject the company to fines of as much as $1.3 million a day.
