The U.S. Supreme Court is set to hear a case centering on contraception, religion, and Obamacare. 

Justices will hear oral arguments tomorrow over whether business owners can object to a provision of the Affordable Care Act that requires employers to provide health insurance that covers birth control. 

Owners of Hobby Lobby, Mardel and Conestoga Wood Specialties say their religious beliefs prevent them from offering employees such coverage. 

The high court is expected to rule on the case by the end of June.
