I joined my Permanent Subcommittee on Investigations colleagues in addition to, House Judiciary Committee Chairman Jim Jordan (R-Ohio), and Representative Barry Loudermilk (R-Ga.) to send letters to AT&T Inc., T-Mobile USA, Inc., Verizon Communications Inc., and the Federal Bureau of Investigation (FBI) seeking answers about the FBI’s use of cellular data in the investigation into the pipe bombs that were discovered on Jan. 6, 2021 in Washington, D.C.

The letter noted that according to a former FBI official who led the investigation, some of the cellular data that the FBI relied on during its investigation was corrupted, potentially frustrating law enforcement’s efforts to locate the individual(s) responsible for planting the pipe bombs.

However, according to a Jan. 2, 2025 House Subcommittee report, the major cellular carriers stated that they neither provided “corrupted” data to the FBI nor received any notification from the FBI of any issues accessing the cellular data.

The bicameral letters requested the cellular carriers and the FBI provide the actual data that was analyzed for the Senate Subcommittee and House Committee to review and all communications between the FBI and the cellular carriers regarding the FBI’s request and analysis of the data.
