This was about King who represented a small group of people in Virginia saying that the I.R.S. is giving tax credit with A.C.A. that is unconstitutional and they are going to sue Burwell that says that it's constitutional.
It was 6-3 to keep Obama Care the way it is.
How it Affected The country
If it was unconstitutional people would not get tax credit ant it would be more expensive. So it is a law that they can give tax credit.
