TL;DR: Section 702 of FISA lets the government collect communications of foreigners abroad, but in practice, it's become a backdoor to spy on Americans. The FBI conducted 3.4 million warrantless searches of this data in 2021 alone. They targeted Black Lives Matter protesters, January 6 suspects, journalists, members of Congress, and 19,000 political donors. A federal court ruled in 2024 that these searches require a warrant. The law expires April 2026. Congress is debating whether to finally require warrants, or let the surveillance continue.
What Section 702 Actually Does
Section 702 of the Foreign Intelligence Surveillance Act was sold as a way to monitor foreign terrorists. The NSA can collect emails, texts, and calls of non-Americans located outside the U.S. No individual warrant needed: just broad certifications approved by a secret court [1].
Here's the catch: When those foreigners communicate with Americans, Americans' messages get collected too. The NSA calls this "incidental collection." It's not incidental. It's the whole point.
Once American communications are in the database, the FBI can search them. These are called "backdoor searches" or "U.S. person queries." The FBI just types in an American's name, email, or phone number. No warrant. No judge. No probable cause.
If you've ever emailed someone abroad, used WhatsApp to message family overseas, or talked to a foreign colleague, your communications may be in this database. And the FBI can search for them anytime they want.
How Often They Search Americans
The scale is staggering:
- 3.4 million warrantless searches of Americans' data by the FBI in 2021 alone [2]
- 278,000 FBI searches violated even their own permissive internal rules in one year [3]
- 10,000 government employees have authority to search Section 702 data [4]
- 4,000 FBI searches in 2022 violated the rules governing FISA databases [3]
The FBI claims searches dropped to 5,518 in 2024 after reforms. Don't celebrate. The FISA Court discovered FBI personnel used an "advanced filter function" that conducted additional U.S. person queries beyond those logged and reviewed [5]. The real number is unknown.
Who They've Targeted
This isn't hypothetical. We know who the FBI searched:
Protesters
The FBI performed "tens of thousands" of searches "related to civil unrest." That included searches targeting 141 people protesting the murder of George Floyd [3]. Exercising your First Amendment rights? You're in the database.
Political Donors
The FBI searched the communications of 19,000 donors to a congressional campaign [3]. The crime? Giving money to a politician.
Members of Congress
FBI agents queried Section 702 databases for communications of sitting members of Congress [4]. The people who are supposed to oversee the FBI? The FBI is surveilling them.
Journalists
Reporters have been searched in Section 702 databases. The surveillance state doesn't like people who report on the surveillance state.
January 6 Suspects
More than 20,000 searches were linked to people "affiliated with" a group suspected of involvement in the Capitol riot [3]. Note the word "affiliated." Not charged. Not convicted. Affiliated.
The December 2025 Hearing
On December 11, 2025, the House Judiciary Committee held a hearing on Section 702. For once, Republicans and Democrats agreed: this needs to change [4].
What the Witnesses Said
Elizabeth Goitein of the Brennan Center testified that the FBI has turned Section 702 into "a go-to domestic spying authority." She explained that requiring a warrant would "put the burden of gatekeeping these searches where it belongs, which is with the courts."
Brett Tolman of Right on Crime called Section 702 the "government's permission slip for warrantless spying on Americans." He warned Congress not to "facilitate a surveillance state."
Chairman Jim Jordan (R-OH) noted that FBI agents conduct three million searches on U.S. persons in one year. He listed targets: journalists, Congress members, Black Lives Matter activists, political donors.
The Oversight Problem
Rep. Deborah Ross raised a critical issue: President Trump fired the Democratic members of the Privacy and Civil Liberties Oversight Board (PCLOB) in January 2025. The board now has one part-time member and can't investigate anything [4].
The FBI Director also eliminated the Office of Internal Auditing established in 2020. The mechanisms meant to prevent abuse? They're being dismantled.
A Court Finally Said No
In December 2024, Judge LaShann DeArcy Hall of the U.S. District Court for the Eastern District of New York made history. She ruled that backdoor searches of Section 702 data require a warrant under the Fourth Amendment [6].
This is the first time any court has said the FBI can't just search Americans' communications whenever it wants. The government is appealing.
For now, the ruling only applies to that district. But it signals that the courts may finally be catching up to the abuse.
It Gets Worse: The Palantir Connection
Section 702 data doesn't stay in one place. Ranking Member Raskin highlighted during the hearing that the government contracts with Palantir to build software that combines:
- Section 702 surveillance data
- Separate departmental databases
- Purchased data broker information
The result? Comprehensive dossiers on Americans built from surveillance data, government records, and commercial data, all without warrants [4].
DOGE (the "Department of Government Efficiency") is now collecting data from Social Security, Treasury, OPM, HHS, VA, and other agencies into a centralized database. Section 702 data could flow right into it.
The April 2026 Deadline
Section 702 expires on April 20, 2026, unless Congress reauthorizes it [5]. This is the window for reform.
In April 2024, Congress passed the Reforming Intelligence and Securing America Act (RISAA), which extended Section 702 for two years. They added some auditing requirements. They didn't add warrant requirements.
The surveillance agencies are already lobbying for renewal. They'll argue national security requires warrantless access to Americans' communications. They'll point to terrorism cases. They won't mention the protesters, the donors, the journalists.
What You Can Do
Protect Yourself
• Use end-to-end encrypted messaging (Signal, Session)
• Minimize communications with foreign contacts through unencrypted channels
• Assume email to/from abroad may be collected
• Use VPNs and Tor for sensitive browsing
Take Action
• Contact your representatives before April 2026
• Demand warrant requirements for U.S. person queries
• Support organizations fighting for reform (EFF, ACLU, Brennan Center)
• Ask candidates their position on Section 702
Stay Informed
• Follow FISA Court decisions
• Track the PCLOB's status (or lack thereof)
• Monitor congressional hearings on surveillance
• Watch for the reauthorization fight in 2026
The Bottom Line
Section 702 was supposed to target foreign terrorists. Instead, it became a tool to search the private communications of millions of Americans (protesters, donors, journalists, even members of Congress) without a warrant.
The FBI ran 3.4 million searches in a single year. They violated their own rules hundreds of thousands of times. The oversight board meant to prevent abuse has been gutted. A court finally ruled these searches unconstitutional, but the government is appealing.
The law expires in April 2026. That's the deadline. Either Congress requires warrants, or the warrantless surveillance continues.
Your communications are in that database. Whether they stay searchable without a warrant is up to Congress.
