PORTLAND, Ore. (AP) — Oregon officials have taken disciplinary action against four Department of Revenue employees who failed to catch a fraudulent tax return that resulted in a 25-year-old woman receiving a $2.1 million refund.

Two employees have been reassigned to jobs in which they will no longer have the authority to approve cash refunds, spokesman Derrick Gasperini said Wednesday. Two others received unspecified disciplinary action for the blunder, but can stay in their current positions,
