House Oversight Committee Chair Carolyn Maloney (D-N.Y.) issued a subpoena to Postmaster General Louis DeJoy on Monday for records related to recent operational changes at the U.S. Postal Service, alleged that he had failed to respond to a voluntary request for documents.

Why it matters: Democratic lawmakers have sounded the alarm in recent weeks over cost-cutting measures and modifications to mail-processing practices that they fear could delay election mail, disenfranchise voters and delay election results. DeJoy testified in a combative hearing before the committee last week that he was not seeking to "sabotage" election mail, but would not commit to reversing changes.

• DeJoy said in a letter to the committee that he trusts his testimony "clarified any outstanding questions you had."
• He has "not produced a single additional document since the House and Senate hearings were held," according to Maloney.

Details: The subpoena requests all documents "referring or relating to proposed or actual changes to operations, policies, practices, or standards."

• It asks that DeJoy share communications between he and Treasury Secretary Steve Mnuchin, White House Chief off Staff Mark Meadows, and any other White House officials or members of the Trump campaign.
• It also asks for the term sheet for the $10 billion loan to USPS from the CARES Act.

What she's saying: “This subpoena includes in one place many requests previously made by Members of the House and Senate in writing and directly to Mr. DeJoy during his in-person testimony,” Maloney wrote. 

• “The subpoena clarifies a number of previous requests based on information obtained to date in order to ensure that it captures all documents within the requested categories, and it also makes clear as a legal matter that the production of these documents is mandatory.”

Worth noting: Postal Service Inspector General Tammy Whitcomb is also reviewing the policy changes, along with potential conflicts of interest involving DeJoy, following a request from Democrats.
