A significant data-sharing breach has emerged involving health information on millions of Americans. According to court filings released this week, Medicaid officials improperly transferred data to Immigration and Customs Enforcement agents in January, and ICE subsequently shared that information with Palantir, a data analytics company that operates a platform called ELITE used by ICE to identify noncitizens subject to deportation.
The disclosure came through a motion filed by more than 20 Democratic attorneys general who are challenging the Trump administration’s data-sharing arrangement between the Centers for Medicare and Medicaid Services and ICE. A federal judge had previously authorized limited data sharing in December, but the revelations show that officials exceeded those parameters. The improperly shared datasets included information on U.S. citizens and legal immigrants, going beyond what court orders permitted.
Federal officials have acknowledged multiple instances of improper data transfers. Most recently, the government revealed that the dataset initially shared improperly in January was reshared with ICE again while transferring data from states not party to the lawsuit. Additionally, ICE personnel discovered that multiple users still retained copies of the January dataset despite deletion efforts. Palantir stated to NPR that the dataset had been purged pursuant to government instructions.
The breaches have raised concerns among state attorneys general about data security and privacy protections. In court filings, they argued that the successive violations undermine confidence in the federal government’s ability to safeguard sensitive health information. A federal judge has scheduled a hearing for August to clarify the scope of what data categories can lawfully be shared with ICE. The Justice Department is simultaneously requesting permission to expand the data-sharing arrangement to include all noncitizens lacking legal permanent resident status.
