Lawyers for the suspect in the Tucson shooting rampage have asked a judge to reject prosecutors' request for his medical records.
Prosecutors requested Jared Loughner's records so they can be used by a psychologist who is conducting a mental competency exam of the suspect at a federal medical facility in Missouri.
Loughner's attorneys say U.S. District Judge Larry Burns should issue an order saying the documents can be used for determining his mental competency and for no other purposes.
The exam is aimed at determining whether Loughner understands the consequences of the charges he faces and can assist in his defense.
Loughner has pleaded not guilty to charges stemming from the Jan. 8 attack that killed six and wounded U.S. Rep. Gabrielle Giffords and 12 others.
