On April 21, 2026, American Oversight, a nonpartisan nonprofit organization focused on government transparency, filed suit against five federal agencies in the U.S. District Court for the District of Columbia. The defendants included the Centers for Disease Control and Prevention (CDC), U.S. Department of Homeland Security (DHS), Immigration and Customs Enforcement (ICE), Internal Revenue Service (IRS), and Social Security Administration (SSA). The lawsuit arose from President Trump's March 20, 2025 executive order calling for federal data sharing across agencies. Following this order, the Trump Administration significantly expanded the government's business relationship with Palantir Technologies, a data analysis firm co-founded by Trump ally Peter Thiel and led by Alex Karp, who donated $1 million to MAGA Inc. Palantir allegedly secured federal contracts exceeding hundreds of millions of dollars with multiple agencies, raising concerns among privacy advocates and lawmakers about potential construction of a government surveillance state. American Oversight brought two FOIA claims alleging the agencies failed to conduct adequate searches for responsive records and wrongfully withheld non-exempt records.
