COVERAGE FOR ILLEGAL ALIENS???

That's another wingnut meme and the answer is, "not so much, really." This is from H.R. 3200, page 143:

3 SEC. 246. NO FEDERAL PAYMENT FOR UNDOCUMENTED
4 ALIENS.
5 Nothing in this subtitle shall allow Federal payments
6 for affordability credits on behalf of individuals who are
7 not lawfully present in the United States.
