The attorney for the man accused of opening fire at Fort Hood has blocked a military-ordered mental exam for his client.

John Galligan is the lead defense attorney for Maj. Nidal Hasan (nih-DAHL' hah-SAHN'). He said he gave written objections Thursday to the three-member board of military mental health professionals who will determine whether Hasan is competent to stand trial.

The panel also will determine Hasan's mental status the day of the Nov. 5 shooting that left 13 dead and nearly three dozen wounded on the Texas Army post.

Galligan said he and the panel went inside the jail to see Hasan, who signed a document saying he did not want to be evaluated at this time. Galligan said the panel also signed the document and left.
