The Agriculture Department wants to curb the practice by giving states more power to investigate people who repeatedly claim to lose their benefit cards.

Those who don't comply can be denied further cards. ___ US bank earnings rose this winter to 5-year high WASHINGTON (AP) â¿¿ U.S. bank earnings rose in the first three months of the year to the highest level in nearly five years and the number of troubled banks fell for the fourth straight quarter. The mostly positive first-quarter earnings released Thursday illustrate how far the banking industry has come since the 2008 financial crisis. Still, the report noted that many banks remain cautious about lending, a necessary driver of economic growth. The Federal Deposit Insurance Corp. said the banking industry earned $35.3 billion in the January-March period. That's up from $28.7 billion in the first quarter of 2011 and the highest level since the second quarter of 2007.
