This bill makes significant changes to how the government can search through intelligence data collected on foreign targets. Currently, federal agencies can search through massive databases of communications without a warrant to find information about Americans. This bill would require law enforcement and intelligence agencies to get a warrant before they can search for an American's communications or personal information in these databases, with limited exceptions for genuine emergencies and cybersecurity threats. The bill also restricts the government's ability to buy personal information about Americans from data brokers without a court order. Essentially, it's designed to prevent the government from using intelligence collection tools—originally meant to spy on foreign threats—as a backdoor way to investigate Americans without judicial oversight. The bill also requires more transparency and reporting to Congress and the courts when these exceptions are used, and it mandates declassification of certain court opinions that have been kept secret.

To amend the Foreign Intelligence Surveillance Act of 1978 to implement reforms, to amend title 18, United States Code, to prevent law enforcement and intelligence agencies from obtaining certain commercially available information, and for other purposes.
