WATCH LIVE: Postmaster General Faces Senate Over Mail-In Voting, COVID-19 Concerns

U.S. Postmaster General Louis DeJoy will take questions from senators at 9 a.m. on Friday.

These are DeJoy's first public remarks since reversing his plan for operational changes that drew heavy criticism. As NPR reports, the U.S. Postal Service has suffered from financial problems for years but DeJoy, a Republican fundraiser, chose this summer to cut overtime, withdraw sorting machines and impose other changes that have effectively reduced the system's throughput. Democrats say this was part of a scheme by President Trump to foil vote-by-mail efforts.
