Supporters say agencies have used commercial data purchases to access information that courts have said is protected by the Fourth Amendment, bypassing warrant requirements.
It's a proposed law that would stop federal agencies from buying personal data — like location records — from companies when the Constitution would normally require them to get a warrant first.
Opponents and some agencies argue that commercially available data is a useful investigative resource and that restrictions could impede counterterrorism, immigration, and criminal probes.
The bill's progress signals how Congress may approach broader questions about commercial surveillance and the boundary between private markets and constitutional protections.
The legislation would bar covered federal agencies from buying or otherwise obtaining from third parties certain categories of data — including location and online activity — about U.S. persons.
Agencies would need to use traditional legal process, such as a warrant, subpoena, or court order, to acquire data that falls within the bill's scope.
The House passed the measure in 2024, but it requires Senate passage and a presidential signature to take effect; until then, existing rules on government data purchases remain in place.
