NSA Warrantless Surveillance (Terrorist Surveillance Program)

Record	OBS-0504
Category	Government/Surveillance
Status	PARTIALLY SUBSTANTIATED
Summary	The claim is that after the 9/11 attacks, the NSA, under President George W. Bush, conducted warrantless surveillance of communications involving U.S. citizens without FISA warrants. Proponents argue this was illegal and violated the Fourth Amendment. The program was revealed in 2005 and allegedly ended in 2007.
Origin	Initiated in late 2001, shortly after the September 11 attacks, and publicly revealed in December 2005 via a New York Times report.
Claimed	The NSA monitored phone calls, internet activities, and other communications without obtaining FISA warrants. The surveillance included communications where one party was in the U.S. and the other was believed to be outside the U.S. The program was an effort to silence critics of the Bush administration. AT&T cooperated by installing fiberoptic splitters to copy internet traffic for the NSA. The government collected phone metadata of all U.S. customers under the Patriot Act.
Evidence / consensus	Government officials and documents confirm the existence of warrantless surveillance programs, but the legality and scope remain debated. Courts have not definitively ruled on the constitutionality, and the government has invoked state secrets privilege. The program was later modified by the FISA Amendments Act of 2008.

> OBSERVER NOTE:
A well-documented program, confirmed by leaks and government admissions. The legal status remains murky, with courts avoiding a final ruling on the merits.
