Social Security benefit fraud is the subject of a hearing today being chaired by Senator Chuck Grassley. The Iowa republican says America’s “most vulnerable citizens” who are elderly, very young or disabled are being victimized financially.Grassley plans to introduce a bipartisan bill that would address the problem of people who are supposed to be helping social security beneficiaries but are really stealing from them. He says the bill would restore benefits to victims more quickly and it would require greater accountability from organizations that handle social security benefits.Grassley is chair of the Senate Special Committee on Aging. He says more than six million Americans who get Social Security have someone else managing their money. Fraud losses reportedly exceed seven million dollars.
