Thomas W. Hartmann is an American lawyer and officer in the United States Air Force Reserve. In July 2007 Brigadier General Hartmann was appointed the Legal Adviser to the Convening Authority in the Department of Defense Office of Military Commissions. After military judges barred him from further involvement in three separate trials, on September 20, 2008 Hartmann was transferred to a new position at Guantanamo as director of operations, planning and development. Hartmann reports to Susan Crawford, a retired judge, who is the Convening Authority.
Colonel Morris Davis, the Guantanamo military commission's senior prosecutor complained that Hartmann was overstepping his authority. He has issued a statement where he wrote:
"...for the good of the process.... If he believes in military commissions as strongly as I do then let's do the right thing and both of us walk away before we do more harm."
