New York Attorney General Letitia James filed suit Tuesday in the US District Court for the District of Columbia against Donald Trump, in his capacity as President, Louis Dejoy, in his capacity as Postmaster General, and the US Postal Service (USPS). Joined in the complaint as plaintiffs are the states of Hawaii, New Jersey, and New York, and the city and county of San Francisco.

The suit is aimed at blocking changes that could impact mail-in voting during the upcoming election. The suit states that beginning in June 2020, the USPS began to make substantial policy changes that affected operational efficiency and the timely delivery of mail. Evidence presented in the complaint includes the fact that “the U.S. Postal Service removed hundreds of collection boxes and high-speed sorting machines; cut or curtailed overtime; prohibited needed late trips and extra trips; and began a pilot program in almost 400 localities that turned how the agency processes mail on its head.” The complaint also includes examples of counties whose mail services were impacted by the changes, as well as a series of Trump tweets, demonstrating his views on mail-in voting.

Other states, such as Pennsylvania and Washington, have filed suits on similar grounds.

Plaintiffs are asking the court to declare the changes unconstitutional and to enjoin the defendants and any of their associates from furthering the postal policy changes.
