The VA 's Office of Inspector General confirmed in August 3,500 veterans had been waiting for appointments on secret lists at the Phoenix VA. At a congressional hearing in September , the VA inspector general Richard Griffin said long wait times at the Phoenix VA , some of which were hidden from VA headquarters , contributed to patient deaths . With the announcement of Helman 's termination , VA Secretary Robert McDonald said in a statement `` lack of oversight and misconduct by VA leaders runs counter to our mission of serving Veterans , and VA will not tolerate it .

Chairman of the House Committee on Veterans Affairs Jeff Miller previously criticized the VA for stalling the firing of Sharon Helman , noting that she continued to be paid after she was placed on leave in May . On Monday , Miller called on the VA to fire additional officials . `` Sharon Helman 's removal is a positive step , but there are still many more VA scandal figures who also must be purged from the department 's payroll in order for veterans and families to receive the closure they deserve , '' Miller said .
