A military official says the man charged with trying to assassinate Rep. Gabrielle Giffords in a shooting rampage was rejected from the Army in 2008 because he failed a drug test.

The official spoke Monday on condition of anonymity because privacy laws prevent the military from disclosing such information about an individual's application.

The official did not know what type of drug was detected in the screening.

The Army has confirmed publicly that Jared Loughner tried to join the Army in December 2008, but never was allowed to serve.
