HARRISBURG/SEATTLE (AP) – PA Attorney General Josh Shapiro and Washington state Attorney General Bob Ferguson are leading states that are suing to block service changes at the U.S. Postal Service. They made the announcement as the U.S. postmaster general announced the reversal of some postal service changes amid a national outcry. In filing the lawsuit, the two Democrats cited policy changes that included limiting worker overtime and late or extra shifts. They say the postmaster general ignored rules requiring the postal service to follow procedures before making changes that affect national service.
