(Harrisburg) -- A new office aims to serve as a watchdog within the state agency tasked with helping the most vulnerable Pennsylvanians. The Department of Public Welfare's Bureau of Public Integrity seeks to root out fraud and waste within the agency. Spokeswoman Carey Miller says the new office won't add to DPW's budget. "The Bureau of Program Integrity was developed with existing staff and resources and it's been people who have been going through and reviewing programs and services to see if there were any issues of fraud, waste or abuse. Then we just started cleaning up," Miller says. She says the new office was born out of a nearly year-long internal review of the agency. It found about 100,000 ineligible people on the state's welfare rolls, including some who were dead or had moved out of the Commonwealth. Miller says auditing the welfare rolls alone saved taxpayers $34 million.
