It's right there in the article, there are specific federal laws authorizing them to make specific information available - for example, they can make any record kept about the identity or location of aliens available. Right, that's a specific limitation on what they can share, even the HHS spokesperson made clear they don't share information on US citizens and permanent lawful residents. But then the article goes on to reveal that ICE has all the personal data of every person receiving Medicaid.

If the law says you can share aliens information, but not Americans information, and then you do share Americans information I think you're probably breaking the law, and at the very least there should be a process to find out what the basis is for you doing it. Normally these things would be decided by a court.
