OKLAHOMA CITY (AP) — Christian-oriented Hobby Lobby Stores Inc. filed a federal lawsuit Wednesday challenging a mandate in the nation’s health care overhaul law that requires employers to provide coverage for the morning-after pill and similar drugs.

The lawsuit by the Oklahoma City-based chain claims the government mandate is forcing the company’s owners “to violate their deeply held religious beliefs under threat of heavy fines, penalties and lawsuits.” Failure to provide the drugs in the company’s health insurance plan could lead to fines of up to $1.3 million a day, the company said.
