NSA Mass Surveillance
Edward Snowden's 2013 revelations proved the NSA was collecting phone records of millions of Americans and had direct access to servers of major tech companies through programs like PRISM and XKeyscore.
In 2013, Edward Snowden proved what civil liberties advocates had been saying for years: the NSA was collecting the phone records of virtually every American, had direct access to the servers of Google, Apple, Facebook, and Microsoft, and could search anyone's emails and browsing history in real time. The government's response was not to deny it — it was to charge Snowden with espionage.
Overview
In June 2013, former NSA contractor Edward Snowden provided journalists Glenn Greenwald, Laura Poitras, and Barton Gellman with thousands of classified documents revealing the scope of NSA surveillance programs. The revelations showed that the agency was collecting metadata on virtually all domestic phone calls, had direct access to the servers of major tech companies through PRISM, and operated XKeyscore — a system allowing analysts to search virtually everything a person does on the internet.
PRISM, authorized under Section 702 of the Foreign Intelligence Surveillance Act, provided the NSA with direct access to data from Google, Apple, Facebook, Microsoft, Yahoo, and other tech companies. While the program was ostensibly targeted at foreign communications, the NSA routinely collected communications of Americans who were in contact with foreign targets — a practice known as "incidental collection."
The Five Eyes alliance — comprising the intelligence agencies of the US, UK, Canada, Australia, and New Zealand — enabled data sharing that allowed agencies to circumvent domestic surveillance restrictions. The UK's GCHQ operated Tempora, which tapped undersea fiber optic cables to collect vast quantities of internet traffic.
The revelations led to significant reforms including the USA FREEDOM Act of 2015, which ended the bulk phone metadata collection program, and changes to the FISA Court's procedures. However, Section 702 has been repeatedly reauthorized by Congress, and many surveillance capabilities remain in place.

Key Players
Edward Snowden

Glenn Greenwald
Received Snowden's documents and published initial revelations in The Guardian.
Keith Alexander
Oversaw the surveillance programs exposed by Snowden. Defended bulk collection as essential to national security.
The Scope of Collection
The Snowden documents revealed surveillance programs of staggering scope. The NSA collected metadata on virtually every phone call made in the United States — who called whom, when, and for how long. XKeyscore allowed analysts to search emails, browsing history, and chat logs in real time.
The agency tapped fiber optic cables, intercepted communications from data centers of major tech companies, and even spied on allied heads of state including German Chancellor Angela Merkel. Documents showed the NSA had the capability to access the content of communications, not just metadata, through multiple programs.
FISA Court opinions, declassified after the revelations, showed the court had repeatedly found NSA programs in violation of the Fourth Amendment but ultimately allowed them to continue with modifications.
The Lies to Congress
In March 2013 — three months before the Snowden revelations — Senator Ron Wyden asked Director of National Intelligence James Clapper in a public hearing: "Does the NSA collect any type of data at all on millions or hundreds of millions of Americans?" Clapper responded: "No, sir. Not wittingly."
This was a lie, as the Snowden documents proved months later. The NSA was collecting metadata on virtually every phone call in the United States. Clapper later said he gave the "least untruthful" answer he could in a public setting. He was never prosecuted for lying to Congress, despite 18 U.S.C. § 1001 making false statements to Congress a federal crime.
The contrast with Snowden's treatment is the point: the man who revealed illegal surveillance was charged under the Espionage Act, while the man who lied to Congress about that surveillance faced no consequences. The message to future whistleblowers was unambiguous.
Section 702 and the Ongoing Fight
Despite the reforms of the USA FREEDOM Act, the core surveillance authorities remain intact. Section 702 of the Foreign Intelligence Surveillance Act — the legal foundation for PRISM — has been reauthorized by Congress multiple times, most recently in 2024.
Section 702 authorizes surveillance of foreign targets, but the "incidental collection" of Americans' communications is massive. A declassified FISA Court opinion found that the FBI conducted as many as 3.4 million warrantless searches of Section 702 data for information about Americans in a single year.
The FISA Court, which oversees these programs, operates in secret, hears only the government's arguments (no adversarial process), and has approved over 99.97% of government surveillance requests since its creation. Civil liberties organizations have called it a "rubber stamp court." The court's defenders argue the high approval rate reflects the government's careful preparation of applications, not rubber-stamping.
The Bottom Line
Mass surveillance did not end with Snowden's revelations — it was legalized. The programs continue under renewed congressional authority, the FISA Court continues to operate in secret, and the man who revealed illegal surveillance lives in exile while the man who lied about it to Congress never faced charges.
