(Golden Valley, MN)  —  Minnesota Lottery officials are investigating after the state’s system caused the Powerball drawing to be delayed by nearly ten hours.  Officials say the state’s sales verification system caused a processing delay on Monday.  Lottery representatives say the delay was needed to confirm the security and accuracy of the drawing and that the process was never compromised.  The Minnesota Lottery says it will provide more information once a “thorough review” is completed.
