FORT HOOD, Texas (AP) — A pretrial hearing has been rescheduled for Tuesday in the murder case against an Army psychiatrist charged in the Fort Hood shooting rampage.

According to a Sunday statement from Fort Hood, a judge will consider whether to postpone Maj. Nidal Hasan’s trial from Aug. 20 until Dec. 3.

The trial judge, Col. Gregory Gross, called off a June 8 pretrial hearing after Hasan appeared in court wearing a beard. He said Hasan’s appearance violated Army regulations and was considered a disruption to the proceedings.

Hasan faces the death penalty if convicted of 13 counts of premeditated murder and 32 counts of attempted premeditated murder in the November 2009 attack.
