(Salem, OR)  --  The Oregon Department of Veterans' Affairs says sensitive information on nearly a thousand of the state's veterans may have been compromised.  The department says an investigation shows that an unauthorized party handled documents containing sensitive information and certifies that a soldier has been discharged from active duty.  The department says the documents contain information, such as the names, security numbers, dates of birth, and addresses of 976 veterans.  Officials say there's no evidence that any attempt has been made to misuse the information.
