A former FBI agent who was charged with joining a mob’s attack on the U.S. Capitol and cheering on rioters is now working as an adviser to the Justice Department official overseeing its “weaponization working group,” which is examining President Donald Trump’s claims of anti-conservative bias inside the department.

The former FBI supervisory agent, Jared Lane Wise, is serving as a counselor to Justice Department pardon attorney Ed Martin Jr., who also serves as director of the working group, according to a person familiar with the matter. The person was not authorized to publicly discuss a personnel matter and spoke on condition of anonymity.

A department spokesperson declined to comment. The New York Times was first to report on Wise’s appointment.
