Postmaster general agrees to testify amid mail-in

House Democrats said Monday that Postmaster General Louis DeJoy has agreed to their demand that he testify next week about controversial changes he's making to the United States Postal Service amid a political firestorm over mail-in voting and claims President Donald Trump was was trying to "sabotage" the November election.

House Oversight and Reform Chairman Rep. Carolyn Maloney, D-N.Y., said in a statement Monday she was "pleased" that DeJoy has agreed to testify about "the sweeping operational and organizational changes he has been making to the Postal Service."

"I also look forward to receiving his production of documents and other information by this Friday in response to the detailed request I made last week with Speaker Pelosi, Leader Schumer, Chairperson Lofgren, and Senate Ranking Members Peters and Klobuchar," the statement continued. "The American people want their mail, medicines, and mail-in ballots delivered in a timely way, and they certainly do not want drastic changes and delays in the midst of a global pandemic just months before the election."

DeJoy was previously scheduled to testify on Sept. 17, which he had indicated was his first availability according to the committee, but several Democrats requested that Maloney move up the hearing amid mounting mail-in voting concerns.

In letters sent Sunday, Maloney called on DeJoy and Robert Duncan, the chairman of the USPS Board of Governors, to produce documents requested by the committee by Friday, Aug. 21, and to testify on Monday, Aug. 24. Both officials were asked to respond by Monday about whether they intended to comply voluntarily with the amended timeline.

Asked on Monday if he's ever asked DeJoy to slow the mail, Trump said "no" and he "wouldn't do that."

"I have encouraged everybody to speed up the mail, not slow the mail. And I also want to have a post office that runs without losing billions and billions of dollars a year as it has been doing for 50 years," he said.

In a news conference in New York on Sunday, Senate Minority Leader Chuck Schumer called on Senate Homeland Security Chairman Ron Johnson to hold a Senate hearing with DeJoy and said DeJoy should be removed from his post if he refuses to appear.

"If Mr. DeJoy refuses to appear he should be stamped return to sender," Schumer said during the press conference Sunday."He should not be allowed to be the postmaster general if after all this destruction he can't answer to the American people what he is doing."

Schumer was among several top Democrats including House Speaker Nancy Pelosi who signed a ten-page letter to DeJoy sent last week calling for documents to be produced by Friday.

“We urge you not to increase costs for election officials and to direct all Postal Service employees to continue to prioritize delivery of election mail so that voters and election workers have ample time to request and send election mail," the letter said.
