FBI surveilled Republican lawmakers' calls during Jan. 6 probe, sparking political backlash.

A September 2023 FBI document obtained by Fox News and reviewed by the FBI reveals that the FBI’s Cellular Analysis Survey Team tracked call metadata from nearly a dozen Republican senators and one House member during the "Arctic Frost" investigation into the January 6 Capitol attack and the 2020 election. The surveillance, linked to former Special Counsel Jack Smith’s probe, included phone numbers, call origins, and locations. FBI Deputy Director Dan Bongino briefed the affected lawmakers, sparking outrage among Republican leaders who called the actions a political abuse of power, a violation of constitutional rights, and a misuse of federal surveillance. They demand answers on who authorized the monitoring and whether laws were broken, intensifying debate over oversight and the use of surveillance in political investigations.
