While some agencies have resisted efforts by Elon Musk’s team to access confidential records, HUD has opened the door. The potential harm to privacy could be significant.

Elon Musk’s Department of Government Efficiency has gained access to a U.S. Department of Housing and Urban Development system containing confidential personal information about hundreds of thousands of alleged victims of housing discrimination, including victims of domestic violence.

Access to the system, called the HUD Enforcement Management System, or HEMS, is typically strictly limited because it contains medical records, financial files, documents that may list Social Security numbers and other private information. DOGE sought access, and HUD granted it last week, according to information reviewed by ProPublica and two officials familiar with the matter.
