WHAT: SSA's Supplemental Security Income program sends checks to 7.8 million aged, blind and disabled people annually.

WHY IT'S AN OUTRAGE: An inspector general's report last year found that SSI staff's manual calculations of benefits were wrong 30 percent of the time, resulting in overpayments of $7.7 million to some 14,400 recipients and underpayments of $6.7 million to 18,500 more. Some recipients had been both overpaid and underpaid.
