Des Moines Register: U.S. Rep. Cindy Axne failed to properly disclose between about $43,000 and $645,000 in stock trades, a nonpartisan government oversight group said Wednesday. The Campaign Legal Center accused Axne, Iowa's lone Democrat in Washington, and six other members of Congress of failing to file periodic transaction reports relating to stock trades. Failing to file those public reports within 45 days of the trades violates the Stop Trading on Congressional Knowledge, or STOCK, Act.
