This bill would significantly restrict how federal intelligence agencies can conduct surveillance on American citizens. It amends the Foreign Intelligence Surveillance Act of 1978 to prohibit the government from using that law to electronically surveil U.S. persons, conduct physical searches of their property, install monitoring devices, obtain their records, or target them for information gathering. The bill also blocks the government from using any information obtained through intelligence surveillance against U.S. citizens in criminal, civil, or administrative court proceedings or investigations, with a narrow exception allowing individuals who were actually surveilled to use information about themselves in legal proceedings. Additionally, the bill extends similar restrictions to surveillance conducted under Executive Order 12333, which governs broader intelligence activities. The legislation contains no specific funding allocations or implementation timelines, as it primarily functions as a restriction on existing intelligence authorities rather than a program requiring appropriations.
