WASHINGTON — Sens. Adam Schiff of California and Ron Wyden of Oregon are demanding answers from Flock Safety about how the company collects, stores and shares license-plate data, including whether federal immigration authorities have improperly accessed its systems. In a letter sent Wednesday to Flock CEO Garrett Langley, the Democratic senators questioned whether the company has adequate safeguards to protect civil liberties as its network of automated license-plate readers expands. They asked Langley to respond by Sept. 25 and preserve records involving Flock, local and state law enforcement agencies, Immigration and Customs Enforcement and the Department of Homeland Security. “Flock has repeatedly failed to implement the safeguards necessary to protect Americans’ civil liberties,” Schiff and Wyden wrote, according to the letter. They said the company’s growth has continued despite what they described as troubling incidents involving potential misuse of its technology. A Flock spokesperson said the company appreciated the senators’ interest and was willing to answer their questions. The lawmakers cited allegations that ICE officials were able to view Flock data, as well as a recent Texas case in which police reportedly used the company’s database to track a woman seeking an abortion. They also raised concerns about a potential partnership with Nexar, a dashcam manufacturer, that could collect information from roughly 350,000 devices installed in rideshare vehicles. Schiff and Wyden said that arrangement could create a far-reaching surveillance system without sufficient consumer consent, transparency or public accountability. The senators also questioned how Flock operates across a patchwork of state and local privacy rules and whether the company complies with California’s privacy protections. Flock has previously argued that local and state officials—not the company—decide how its technology is used. The company has also announced measures intended to limit abuse, including suspending accounts for suspicious activity and shortening its default data-retention period from 30 days to seven days. Schiff and Wyden questioned whether those measures are strong enough to prevent improper searches or unauthorized access. The inquiry is part of growing bipartisan scrutiny of automated license-plate readers, which record vehicle locations and can allow authorities to reconstruct people’s movements even when drivers are not suspected of a crime. Communities nationwide have begun reviewing or canceling contracts with Flock amid concerns about police misconduct, immigration enforcement and the lack of meaningful public oversight. The Senate Judiciary Subcommittee on Crime and Counterterrorism, chaired by Sen. Josh Hawley, Republican of Missouri, is scheduled to hold a hearing next Wednesday titled “Always Watching: Flock’s Nationwide AI Surveillance Network.” Hawley opened an investigation last month into possible misuse of Flock and similar systems. Flock officials could be invited to testify, although a witness list had not been released. Law enforcement agencies have defended the cameras as useful tools for identifying vehicles connected to crimes. President Donald Trump has voiced support for Flock cameras, and FBI Director Kash Patel has defended the technology’s use by federal authorities. Because Schiff and Wyden are in the Senate minority, they have limited ability to compel Flock to provide records or testimony. That could change if Democrats regain control of the chamber after the midterm elections. Schiff serves on the Senate Judiciary Committee, while Wyden is the top Democrat on the Finance Committee.
