The lawyer for the 89-year-old white supremacist accused of fatally shooting a guard at Washington's Holocaust museum says his client's medical condition could make it difficult to bring him to court hearings.

James von Brunn is being held at Butner Federal Medical Center in Butner, N.C. Federal Defender A.J. Kramer suggested in court Monday that the judge could hold a competency hearing there if von Brunn can't travel.

Von Brunn was shot in the face after he allegedly shot a security guard at the Holocaust Memorial Museum in June. He also has chronic medical problems.

U.S. District Judge Reggie B. Walton earlier granted prison officials an extension until Jan. 2 for von Brunn's psychiatric evaluation.

Walton set the next hearing for Jan. 26, but von Brunn isn't expected to be there.
