"I don't care if the federal government is telling me to buy my employees Jack Daniel's or birth control. What gives them the right to tell me that I have to do that?…I'm not trying to get birth control out of Rite Aid or Wal-Mart, but don't tell me I gotta pay for it."

In Michigan, there's Trijicon, a military contractor specializing in optics equipment for weapons. The company last made headlines in 2010, when it came under fire for stamping references to Bible verses on its combat rifle sights. According to data provided to Mother Jones by the Department of Defense, Trijicon currently holds at least $8.9 million in active contracts with the US military.

In its August 2013 lawsuit, Trijicon claims that the company "and its shareholders have a deeply held religious belief that life begins at conception/fertilization." The company's website states: "We believe that America is great when its people are good. This goodness has been based on biblical standards throughout our history and we will strive to follow those morals." Depending on where the Supreme Court lands on Hobby Lobby, that belief could mean no more birth control coverage for the company's 257 employees, 212 of whom are currently enrolled in the company's insurance plan.
