Medicaid Data Sharing Breach: ICE’s Improper Handling Sparks Controversy

Data Misuse Sparks Controversy Between Medicaid, ICE, and Palantir

Recent court filings have unveiled a significant breach of protocol where Medicaid officials improperly shared data with immigration authorities. This data was subsequently handed over to the data analytics company, Palantir, as acknowledged in new legal documents.

Palantir, known for its ELITE app used by ICE agents, leverages this information to pinpoint the locations of noncitizens for potential deportation actions. The revelation emerged in a motion from over 20 Democratic attorneys general, who had previously litigated against the Trump administration over the data-sharing agreement between the Centers for Medicare and Medicaid Services (CMS) and ICE.

In December, U.S. District Judge Vince Chhabria permitted health officials to provide ICE with specific Medicaid data concerning immigrants without legal status. However, this was halted temporarily in May after federal officials disclosed that CMS had transmitted data to ICE in January that exceeded the court’s stipulations. This included datasets with refugee information from Minnesota and data encompassing millions of individuals, some legally present in the U.S.

ICE was ordered to expunge the data in question, and a hearing is scheduled for August to further define the boundaries of data sharing permissible under the court’s order. Nevertheless, recent admissions indicate ongoing issues with data handling.

The Justice Department confessed last week that CMS mistakenly re-sent the dataset with millions of names to ICE, originally shared in January, during an attempt to distribute data from non-litigating states. Alberto Briseno of ICE’s Homeland Security Investigations confirmed the file was deleted upon discovery and was not utilized for enforcement purposes.

However, Briseno later revealed that multiple copies of the dataset still existed within ICE’s systems, underscoring the challenges of ensuring complete data deletion. “ICE will continue to make good faith efforts to delete any copies that may be found in the future,” he stated.

The Department of Justice is now seeking a broader scope from the court to include more noncitizens in the data-sharing mandate, sparking criticism from the Democratic attorneys general. They argue that ICE’s failure to manage Medicaid records undermines its request for expanded data access.

Palantir has not commented on whether it has erased the dataset shared by ICE, nor has the Department of Homeland Security responded to inquiries about data transfers to Palantir. California Deputy Attorney General Anna Rich’s declaration indicates that data shared with contractors like Palantir was reportedly deleted from a Microsoft Teams chat after plaintiffs pressed for assurances.

In a previous hearing, Judge Chhabria cautioned the federal government against continued misuse of Medicaid data, emphasizing, “If the federal government cannot be sufficiently careful then it can’t use the information, ok?”
