We're talking to you, Rep. Joe Wilson. Factcheck.org:
False: Illegal Immigrants Will Be Covered
One Republican congressman issued a press release claiming that "5,600,000 Illegal Aliens May Be Covered Under Obamacare," and we’ve been peppered with queries about similar claims. They’re not true. In fact, the House bill (the only bill to be formally introduced in its entirety) specifically says that no federal money would be spent on giving illegal immigrants health coverage:
H.R. 3200: Sec 246 — NO FEDERAL PAYMENT FOR UNDOCUMENTED ALIENS
Nothing in this subtitle shall allow Federal payments for affordability credits on behalf of individuals who are not lawfully present in the United States.
Also, under current law, those in the country illegally don’t qualify for federal health programs. Of interest: About half of illegal immigrants have health insurance now, according to the nonpartisan Pew Hispanic Center, which says those who lack insurance do so principally because their employers don’t offer it.
