D.C. Attorney General Karl Racine has joined six other state attorneys general in a lawsuit against the U.S. Postal Service, alleging that Postmaster General Louis DeJoy is attempting to undermine the November election by limiting Postal Service operations.

The lawsuit, filed Friday in the Eastern District of Pennsylvania by Pennsylvania Attorney General Josh Shapiro, claims that the Trump administration’s and DeJoy’s changes to the USPS violate the U.S. Constitution by “interfering with states’ ability to manage their own elections, disproportionately preventing seniors from voting, failing to efficiently deliver mail, and failing to give required notice of nationwide service changes.”

The suit also names Robert M. Duncan, chairman of the Postal Service Board of Governors, as a defendant. Attorneys general from Maine, Massachusetts, North Carolina, Deleware, and California are also part of the filing.

The accusations stem from DeJoy’s recent operational changes to the Postal Service — including a ban on employees working overtime and making extra trips, and the removal of mail boxes — that have caused delays and backlogs in delivery, threatening mail-in ballot initiatives for the election. DeJoy claimed the measures were necessary as the Postal Service faces a billion dollar shortfall, but recently suspended any changes to service until after the election, to “avoid even the appearance of any impact on election mail.”

A Postal Service representative declined to comment on the suit, and referred DCist/WAMU to DeJoy’s statement about suspending changes.

“Americans need a safe, secure, and reliable way to cast their ballots as COVID-19 continues to spread. Allowing everyone the choice to vote by mail — as President Trump himself has done in several recent elections — is the obvious answer,” Racine’s press release about the suit reads. “Our coalition of state attorneys general is working to undo the damage already done and make sure everyone’s ballot is counted in November.”

Racine filed the lawsuit along with the attorneys general of Pennsylvania, California, Delaware, Maine, Massachusetts, and North Carolina. Earlier this week, Maryland and Virginia joined a separate, complementary suit with 13 other states. On Friday, Virginia Attorney General Mark Herring wrote a letter to the Department of Justice demanding answers about service disruptions at processing centers in the in the state.

Racine’s entrance into the latest litigation against Trump and DeJoy (a major Trump donor) follow weeks of mounting concerns about mail-in ballot delivery in November, and months of poor service for some local residents. The cuts to mail services have already impacted residents in D.C.’s Ward 8, who reported delivery issues in May that stemmed from personnel shortages. Earlier this month, residents in the ward told WJLA that they had been waiting weeks, or even months, for their mail.

If you are a voter in D.C., Maryland, or Virginia, there are a number of ways to vote early and ensure that your ballot is counted on time.
