The documents obtained by the ACLU suggest a similar situation, where a telecommunications firm, whose name is redacted, furnished call-data records the NSA hadn’t requested and weren’t approved by orders of the secretive U.S. Foreign Intelligence Surveillance Court. The company told the NSA it began delivering those records on Oct. 3, 2018, until that Oct. 12, when the agency asked it investigate the “anomaly.”

The ACLU said the documents also suggest an individual may have been targeted for surveillance as a result of the first overcollection episode, which led to the deletion of the program’s entire database in June 2018. The documents reveal that violation involved “targeting requests” that were approved by the surveillance court.

The revelation of another compliance issue is the latest hurdle for the once-secret surveillance program that began under the George W. Bush administration following the Sept. 11, 2001, attacks. As initially designed, the program sought to collect the metadata of all domestic calls in the U.S. to hunt for links among potential associates of terrorism suspects.
