WASHINGTON (AP) — Democratic Speaker Nancy Pelosi is calling the House back into session this week to vote on a bill prohibiting the U.S. Postal Service from changing its operations or level of service. Her decision comes amid growing concerns that the Trump White House is trying to undermine the agency during the coronavirus pandemic as states expand mail-in voting options. The legislation would prohibit the Postal Service from implementing any changes to operations or level of service it had in place on Jan. 1. A vote could come next Saturday. Senate Leader Mitch McConnell, meanwhile, says he’s not recalling senators to Washington.
