Postmaster General Louis DeJoy was grilled by Democrats Monday as he testified before the House Oversight Committee about recent changes at the U.S. Postal Service. DeJoy struggled to answer basic questions, including about mail-in voting during the 2016 elections and the cost of mail. He also refused to provide justification for recent changes at the Postal Service, which has led to a slowing down of delivery times and has prompted fears Trump is deliberately trying to sabotage the USPS in the run-up to the elections.

In related tech news, Twitter flagged a Trump tweet that claimed mailboxes are a “voter security disaster” and “not Covid sanitized.” Twitter said the tweet made “misleading health claims that could potentially dissuade people from participation in voting.”
