A critical pillar of the United States’ intelligence-gathering apparatus is facing a deadline that could depart the spy community blind or force a bruising confrontation over the Fourth Amendment. Section 702 of the Foreign Intelligence Surveillance Act, commonly known as FISA 702, is set to expire on April 20 unless Congress acts to renew it.
The program is described by the federal government as indispensable, providing the raw data that underpins a majority of the president’s daily intelligence briefings. From disrupting international terrorism and tracking the precursors of synthetic drugs to thwarting state-sponsored cyberattacks, the government argues that Section 702 of FISA is the primary tool for detecting threats before they reach American soil.
However, a bipartisan coalition of lawmakers and privacy advocates warns that the tool has evolved into a mechanism for warrantless surveillance of U.S. Citizens. The core of the dispute lies in “incidental collection”—the process where the communications of Americans are swept up when they interact with foreign targets—and the government’s ability to search those databases for Americans’ information without a court order.
The Intelligence Engine: How Section 702 Operates
Under the authority of Section 702, U.S. Intelligence agencies—including the NSA, CIA, FBI, and the National Counterterrorism Center—can collect electronic communications from foreign nationals located outside the United States. Crucially, they can do this without obtaining individual court orders for every target.
The process begins with the Office of the Director of National Intelligence (ODNI) and the Attorney General proposing categories of targets. The Foreign Intelligence Surveillance Court (FISC) then issues a blanket authorization each year. The government obtains the actual data directly from U.S. Companies that provide email, social media, and cellphone services, or by intercepting data as it travels across the internet’s backbone.
The scale of this collection is immense. In 2025, there were 349,823 surveillance targets, a significant increase from roughly 246,000 in 2022. Because a single target may generate thousands of records, the resulting database is a massive repository of global communication.
Why the Government Claims We see Essential
Intelligence officials argue that without this tool, the U.S. Would be blind to critical threats. In 2023, government reports indicated that 60% of the items in the president’s daily intelligence brief contained information derived from Section 702. The program’s utility extends beyond counterterrorism; for instance, 70% of the CIA’s disruptions of illicit synthetic drug trafficking in 2023 were based on FISA 702 data.
Stewart Baker, former National Security Agency general counsel, has emphasized the program’s role in disrupting terrorist attacks, identifying the Chinese origins of fentanyl precursors, and responding to ransomware attacks. He has noted that these examples represent only a fraction of the program’s value.
The Privacy Gap and the ‘Backdoor Search’
The controversy surrounding Section 702 does not stem from the surveillance of foreigners, but from what happens to the data of Americans. When a foreign target communicates with a person in the U.S., that American’s data is “incidentally” collected. This creates a giant database containing the private communications of countless U.S. Citizens.
The central point of contention is the “U.S. Person query.” Federal agents can search this database for information on Americans without a warrant. While the government provides legitimate examples—such as locating a U.S. Hostage or identifying the scope of a cyberattack on a U.S. Victim—critics call these “backdoor searches.”
Elizabeth Goitein, senior director of the Brennan Center’s Liberty and National Security Program, argues that the FBI and other agencies routinely search this data specifically to find Americans’ communications, which she contends violates the Fourth Amendment’s guarantee against unreasonable searches and seizures.
A History of ‘Persistent and Widespread’ Abuse
The argument for stricter oversight is bolstered by documented failures. In a 2022 court document, the Foreign Intelligence Surveillance Court described the FBI’s violations of the program as “persistent and widespread.”
Transparency reports from the ODNI have detailed a series of improper warrantless searches, including queries for:
- A sitting U.S. Senator.
- Journalists and political commentators.
- Approximately 19,000 donors to a congressional campaign.
- 6,800 Social Security numbers.
- A family member of an FBI employee, prompted by a suspicion of an extramarital affair.
A Shifting Political Landscape
Unlike many modern political battles, the fight over FISA 702 does not follow party lines. Skeptics include Republicans like Sen. Mike Lee and Rep. Warren Davidson, as well as Democrats like Sen. Ron Wyden and Rep. Jamie Raskin. The common thread is a desire for a warrant requirement before the government can query the data of U.S. Persons.
The intelligence community, however, warns that such a requirement would be a “de facto ban.” Former FBI Director Christopher Wray has told Congress that the time and resources required to obtain individual warrants for every query would be an insurmountable burden in the face of rapidly evolving threats.
Adding a layer of complexity is the evolving position of President Trump. In April 2024, during the Biden administration, Trump posted on Truth Social, “KILL FISA, IT WAS ILLEGALLY USED AGAINST ME, AND MANY OTHERS.” However, in a recent shift, Trump has called for a “clean 18-month extension,” arguing that the tool is effective for keeping Americans safe and is vital for operations against the Iranian regime.
| Metric | Earlier Period | Recent Period |
|---|---|---|
| Surveillance Targets | ~246,000 (2022) | 349,823 (2025) |
| U.S. Person Queries | 119,383 (Dec ’21–Nov ’22) | 7,413 (2024–2025) |
While the number of queries for Americans has declined dramatically in recent years, privacy advocates argue that the lack of a legal warrant requirement remains a fundamental flaw in the law.
As the April 20 deadline approaches, Congress must decide whether to renew the program as is, implement new civil liberties protections, or allow a key tool of American surveillance to lapse. The next official checkpoint will be the legislative votes leading up to the expiration date.
