5. How did we get here?

This is the next chapter in the pitched legal fight over the Affordable Care Act that was approved by Congress in 2010 without any Republican support.

Obama and Democratic allies moved forward to help provide insurance coverage for tens of millions of Americans without it. So far, 9 million people have signed up for benefits since last October, but Republicans claim the program is too expensive and won't work.

The first lawsuits challenging the healthcare overhaul began just hours after Obama signed it into law.

The landmark June 2012 decision upheld key parts of the Affordable Care Act, ensuring it would move forward.

Nearly 50 pending lawsuits have been filed in federal court from various corporations challenging the birth control coverage benefits. But the Supreme Court will have the final say on those with its decision on Monday.
