Top Democrats on Sunday demanded Postmaster General Louis DeJoy testify before Congress next week and accused the \u0022Trump mega-donor\u0022 of having \u0022acted as an accomplice\u0026nbsp;in the president\u0026#039;s campaign to cheat in the election, as he launches sweeping new operational changes that degrade delivery standards and delay the mail.\u0022The joint statement came from House Speaker Nancy Pelosi,\u0026nbsp; Senate Minority Leader Chuck Schumer,\u0026nbsp; House Oversight Committeee Chairwoman Carolyn Maloney, and ranking Democrat on the Senate Committee on Homeland Security and Governmental Affairs Gary C. Peters. It called for Chairman of the USPS Board of Governors Robert Duncan to also appear before lawmakers.The demands were issued amid\u0026nbsp;swelling outrage and warnings \u0022our very democracy is at stake\u0022 as a result of policy changes imposed by DeJoy that have been blamed for slowed mail delivery and raised fears of election sabotage, and an admission by the president he\u0026#039;s blocking Postal Service funding to stop mail-in voting.\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0022The Postal Service itself has warned that voters—even if they send in their ballots by state deadlines—may be disenfranchised in 46 states and in Washington, D.C.\u0026nbsp;by continued\u0026nbsp;delays. This\u0026nbsp;constitutes\u0026nbsp;a grave threat to the integrity of the election and to our very democracy,\u0022 the Democrats said.The statement points to a letter sent Sunday by Maloney to DeJoy.BREAKINGChair @RepMaloney just called on @USPS PMG DeJoy to testify at an urgent Oversight Cmte hearing on Aug. 24 to examine his sweeping changes and their impact on mail-in voting. #SavetheUSPS Read more here: https://t.co/WETO762Dsq pic.twitter.com/PJn6XPoFHj— Oversight Committee (@OversightDems) August 16, 2020In her letter, Maloney asks for the postmaster general to appear at an August 24th hearing to focus on his \u0022sweeping operational and organizational changes at the Postal Service.\u0022Testimony can\u0026#039;t wait until September when DeJoy previously indicated he\u0026#039;d be first available, Maloney wrote, in light of \u0022startling new revelations about the scope and gravity of operational changes you are implementing at hundreds of postal facilities without consulting adequately with Congress, the Postal Regulatory Commission, or the Board of Governors.\u0022\u0022Your testimony is particularly urgent given the troubling influx of reports of widespread delays at postal facilities across the country—as well as President Trump\u0026#039;s explicit admission last week that he has been blocking critical coronavirus funding for the Postal Service in order to impair mail-in voting efforts for the upcoming elections in November,\u0022 she wrote.The Democrats\u0026#039; joint statement also accused the GOP of being \u0022missing in action\u0022 on the issue and singled out the Republican chair of the Senate Committee on Homeland Security and Governmental Affairs, Sen. Ron Johnson.Peters—who earlier this month launched an investigation into mail delays—sent a letter to Johnson Sunday urging the senator to bring DeJoy and Duncan before the committee \u0022on August 21, or as soon as practicable\u0022 to discuss the recent changes. The testimony is of the utmost importance, Peters wrote, \u0022since the Postal Service is a public institution that both serves and belongs to every person in our nation.\u0022Schumer,\u0026nbsp; for his part, said in a tweet that DeJoy should be ousted if he ignores the Democrats\u0026#039; request.\u0022If Postmaster General DeJoy doesn\u0026#039;t testify before Congress next week as Speaker Pelosi and I have requested,\u0022 Schumer wrote, \u0022he should be stamped, returned to sender, and removed from his position.\u0022According to Vanita Gupta, president and CEO of The Leadership Conference on Civil and Human Rights, \u0022DeJoy should be subpoenaed if he doesn\u0026#039;t respond, and members should resist giving speeches at the hearing.\u0022\u0022They need to ask substantive questions that force him to admit his agenda and reverse his recent changes,\u0022 Gupta tweeted, noting that there are \u0022fewer than 80 days until election.\u0022\u0022Our democracy won\u0026#039;t save itself,\u0022 she wrote.
