Republicans and Democrats clashed over the 2020 presidential election and Louis DeJoy, the former President Donald Trump's controversial postmaster general at a House hearing on postal reform Wednesday. DeJoy came under fire during last year's presidential election for making changes to the postal service, such as reducing overtime, eliminating dropboxes and discarding mail sorting machines, all moves that Democrats saw as designed to curb the effectiveness of mail-in balloting and help Trump's re-election effort. "History has already shown that baseless conspiracy theory to be untrue," said Republican Congressman James Comer of Kentucky. "Somehow you were the worst," said Rep. Jim Jordan, a Republican from Ohio. "Again, all under the guise of creating this crazy chaos that they wanted around the election, relative to mail-in balloting. And you were the guy they used to launch it all to start it all in the summer," Jordan said. "It was a federal judge who found it politically motivated, not a Democratic critic," said Democratic Rep. Gerry Connolly of Virginia. DeJoy apologized for delays in mail delivery in recent months. "All of us at the Postal Service, from our board to our leadership team, to our union association leadership to every employee, strive to do better in our service to the American people, and we will do better, he said. Lawmakers are weighing reform legislation to put the US Postal Service on a sustainable path forward. "The years of financial stress, underinvestment, unachievable service standards and lack of operational precision have resulted in a system that does not have adequate resiliency to adjust and adapt to changing circumstances," DeJoy said.
