John Luman Smith
Early Legal Career
Smith began his federal prosecutorial career as an Assistant U.S. Attorney in the U.S. Attorney's Office for the Middle District of Tennessee. He later served as acting U.S. attorney for that district in 2017.
He subsequently became head of the Public Integrity Section of the U.S. Department of Justice. The section handles federal investigations and prosecutions involving public corruption and related matters.
Work in Public Integrity
During his Justice Department career, Smith worked on cases involving public corruption and other federal offenses. His work included prosecutions involving public officials and individuals accused of corruption-related crimes.
His career in public integrity became one of the principal parts of his professional background before he moved into international criminal justice.
Kosovo Specialist Chambers
In 2018, Smith became chief prosecutor of the Kosovo Specialist Chambers and Specialist Prosecutor's Office in The Hague.
The institution was established to investigate and prosecute certain serious crimes connected with the Kosovo conflict. Smith served as chief prosecutor from 2018 until 2022.
His international work expanded his experience beyond the U.S. federal justice system and placed him in an international legal setting.
Appointment as Special Counsel
On November 18, 2022, U.S. Attorney General Merrick Garland appointed Smith as special counsel for the Department of Justice. The appointment gave him responsibility for overseeing two existing federal investigations involving former President Donald Trump.
The investigations concerned allegations related to efforts surrounding the 2020 presidential election and the handling of government records, including classified materials.
Smith's appointment and subsequent investigations received extensive public and political attention because of their connection to a former president and the 2024 presidential election.
The Special Counsel Investigations
During Smith's tenure as special counsel, his office brought federal charges in two separate cases involving Trump.
One case concerned alleged efforts to overturn the results of the 2020 presidential election. Another involved the retention and handling of government documents after Trump left office.
These cases were legal proceedings involving allegations and charges, rather than findings that every allegation had been proven in court. The proceedings also encountered significant procedural and legal developments.
Final Report and Resignation
Smith's tenure as special counsel ended in January 2025. He submitted his final report to Attorney General Garland and resigned from the Justice Department on January 10, 2025.
The U.S. Department of Justice has published official material relating to Smith's appointment and work, including his oath of office.
