Galligan says he can't work on Hasan's case because he needs to meet with Hasan and one of his relatives at the same time.
Hasan is undergoing rehabilitation at a San Antonio military hospital, recovering from wounds that left him paralyzed.
Hasan has been charged with 13 counts of premeditated murder and 32 counts of attempted premeditated murder in the Nov. 5 shooting at the central Texas Army post. He was shot and wounded by Fort Hood police officers, authorities have said.
