Jack Smith may have believed he was untouchable when he led the Biden administration’s high-profile legal campaign against Donald Trump, but a group of Republican lawmakers is now making it clear that his alleged misconduct won’t go unanswered.

On Friday, Sen. Marsha Blackburn of Tennessee, joined by a coalition of Republican senators and one congressman, sent a formal letter to Attorney General Pam Bondi referring Smith to the Department of Justice’s Office of Professional Responsibility and two state bar associations for investigation. The letter accuses the former special counsel of serious professional misconduct that could warrant disbarment, The New York Post reported.

“As part of Jack Smith’s weaponized witch hunt, the Biden DOJ issued subpoenas to several telecommunications companies in 2023 regarding our cell phone records, gaining access to the time, recipient, duration, and location of calls placed on our devices from January 4, 2021, to January 7, 2021,” the letter read. “We have yet to learn of any legal predicate for the Biden Department of Justice issuing subpoenas to obtain these cell phone records.”

The referral follows reports that Smith’s office spied on Republican members of Congress during that same period, using what’s known as a toll analysis — a process that allows investigators to obtain metadata such as call duration, recipient information, and location data from personal devices.
