Surveillance and Domestic Intelligence (FISA)

The Foreign Intelligence Surveillance Act (FISA) governs how U.S. intelligence agencies monitor communications and collect information on foreign targets and Americans. Since the September 11 attacks, surveillance authorities have expanded dramatically, giving agencies like the NSA, FBI, and CIA broad powers to conduct wiretapping, track phone records, and access digital communications—often affecting ordinary Americans.

How Surveillance Authority Works

U.S. intelligence agencies operate under multiple legal authorities. Some programs require approval from the Foreign Intelligence Surveillance Court (FISC), a secret court that oversees surveillance activities. Others fall under broader Executive Order authority. Section 702 of FISA allows the NSA to collect internet and phone communications from non-U.S. persons overseas, with limited restrictions on searching Americans’ information. This authority is set to expire in April 2026 unless Congress reauthorizes it, making it a recurring debate.

Your Digital Privacy and Government Access

Your direct messages, emails, and cloud data can be accessed by government agencies under various legal authorities, though the scope remains contested. These tools—from bulk phone record collection to monitoring international communications—touch nearly every American, raising questions about privacy rights, oversight, and the balance between security and liberty. Congress regularly revisits these laws to expand or restrict powers.
