24 states sue to block new Postal Service rules for mail voting ahead of midterms

TL;DR

  • A coalition of 24 states and D.C. is suing to block new U.S. Postal Service rules for mail voting.
  • The states argue the new rules exceed executive branch power and interfere with state authority over elections.
  • They claim the rule risks disenfranchising voters and will require significant resources and time to implement.
  • The White House states the rules are necessary for mail-in ballot security and election integrity.
  • The rules include requirements for mail ballot envelopes with trackable barcodes and submission of voter lists.
  • A previous legal challenge to President Trump's executive order on mail voting was partially halted by the Supreme Court on procedural grounds.
  • The outcome of the current lawsuit and the implementation of the rules before the November midterms remain uncertain.
