On August 16, 2020,
Speaker of the House Nancy Pelosi ended a recess of the
House of Representatives that had been scheduled to last until the week of September 14, calling lawmakers back to Washington to address the crisis. She proposed an early vote on a bill to roll back the changes introduced by DeJoy, which Democrats have described as "a grave threat to the integrity of the election." Pelosi said that "Lives, livelihoods and the life of our American democracy are under threat from the president."
Senate Minority Leader Chuck Schumer demanded that Majority Leader
Mitch McConnell bring the
Senate back into session also, to consider ways to "undo the extensive damage Mr. DeJoy has done at the Postal Service," but there was no indication McConnell would do so. On August 17, 2020, DeJoy agreed to testify before the
House Committee on Oversight and Reform on August 24, and the next day he agreed to testify before the
Senate Committee on Homeland Security and Government Affairs on August 21.
USPS Board of Governors chairman
Mike Duncan also agreed to testify at the House hearing. Despite DeJoy's announcement that he would be suspending the operational changes until after the election, Pelosi stated that she did not trust DeJoy, and called the suspension "a necessary but insufficient step in ending the president’s election sabotage campaign." On August 21, 2020, DeJoy testified before the U.S. Senate that he votes by mail. He committed to senators at the Senate Homeland Security and Governmental Affairs Committee that voters should be "extremely highly confident" that even mail-in ballots sent close to Election Day would be delivered on time, and promised that the USPS would respect its "sacred duty" to deliver election mail in the fall of 2020. Senator
Jacky Rosen asked DeJoy to provide the sources of data collected, data analyses, and considerations of consequences—specifically on veterans dependent on the mail for their prescriptions—that DeJoy had undertaken before implementing the removal of mail sorting machines, "reduction, elimination of overtime and late trips". The bill was introduced in the Senate by
Susan Collins, but never reached the floor for a vote. Congresswoman
Debbie Wasserman Schultz, a member of the
House Committee on Oversight and Reform, was denied access to two post offices in Florida when she tried to conduct an inspection on September 3. The United States Postal Service cited possible
Hatch Act violations and internal ethics guidelines that stipulate any candidate for political office cannot tour a post office within 45 days of an election as its reasons for turning Wasserman Schultz away. ==Holiday shipping delays==
