I think it's pretty clear they are using Medicare and Medicaid data. They both fall under the umbrella of HHS so it would technically be correct to say they got data from HHS, but it seems like it's specifically Medicare and Medicaid data.

Not necessarily, but probably. I was told explicitly that undocumented migrants weren't getting Medicare and Medicaid services, but at this point, I don't know who to believe.
