Two top supervisors at ATF headquarters in Washington — the deputy director and the assistant director for all field operations — have been reassigned to lower-level positions as the beleaguered agency attempts to remake itself amid the fallout from a failed gun-tracking operation along the Southwest border called Fast and Furious, according to two sources briefed on the changes.

William J. Hoover, the No. 2 man at ATF, will become special agent-in-charge of the agency’s Washington field office, while Mark Chait, who ran all of the field investigations around the country, is being reassigned as head of the Baltimore field office.

Thomas Brandon, who was sent to Phoenix to run the field office there and help it recover from the repercussions of Fast and Furious, will be taking Hoover’s spot as deputy director.
