Maj. Nidal Malik Hasan's attorney is retired Col. John P. Galligan, who has a long history practicing Army law and last served as Chief Circuit Judge at Fort Hood in Texas.
Galligan said on CBS' "The Early Show" that he assured Hasan he'll be fairly treated in the military courts system and his rights will be respected, according to the AP.
Galligan said Hasan, 39, was lucid and knew he was a suspect in the mass killings, "but there were no formal charges that I could discuss with him." The two met on Monday.
Galligan said Tuesday he thought it would be difficult for Hasan to get a fair trial at Fort Hood in Texas "given the national media attention that has been focused" on the massacre, which left 13 dead and more than two dozen wounded.
Hasan is suspected of opening fire the afternoon of Nov. 5 at a military processing center for soldiers coming back from and heading to war in Afghanistan or Iraq.
At the time of Galligan's 2001 retirement, he was serving as the Chief Circuit Judge, 3rd Judicial Circuit, at Fort Hood.
Born in 1949 at Fort Bliss in El Paso, Galligan grew up in a military family and accompanied his parents on assignments to Fort Churchill, Nevada; Canada; Taipei, Taiwan; and Istanbul, Turkey.
After graduating from Georgetown University's School of Foreign Service in 1971, Galligan became a second lieutenant in the military's intelligence division.
He also served at various times as a combat arms officer in the infantry branch, a platoon leader and the Brigade Courts and Boards Officer with the 41st Infantry Combat unit at Fort Ord in California.
He has his law degree from the University of Puerto Rico.
