Senator Chuck Grassley pens letter to USPS about sex offenders working for USPS

According to legally-protected whistleblower disclosures provided to my office, the United States Postal Service (USPS) hired a registered sex offender as a mail carrier. The whistleblower disclosure noted that the employee disclosed his status as a registered sex offender on his job application. It’s been further alleged that instead of firing this individual, USPS placed the individual on administrative leave upon discovering his status.
