Answer: The Preamble of the Constitution
where Health Care is mandated!

The Preamble to the United States Constitution is a brief introductory statement of the fundamental purposes and guiding principles which the Constitution is meant to serve. In general terms, it expresses the intentions of its authors. On occasion, courts have referred to it as reliable evidence of what the Founding Fathers thought the Constitution meant and what they hoped it would achieve.
