From the article:
Last year's Medicare prescription drug law includes one (b) billion dollars for hospitals that treat undocumented immigrants and absorb most of that care.It's like how the federal government exercises unconstitutional control over many things, like your local public school: dangle money, and say what you gotta do to get itTo get the money, hospitals would have to ask about citizenship and how people entered the country to make sure the money was spent on emergency services for undocumented immigrants.
I should have been more clear.
Lots of things exist in laws, but, as you have stated, the laws themselves violate the law of the land.
