A coalition of 24 attorneys general and the state of Pennsylvania filed a lawsuit against the U.S. Postal Service on Wednesday challenging a final rule on mail-in ballots the agency issued last week. They allege the rule illegally interferes with their constitutional authority to administer elections because it allows the USPS to reject mail.

“Ballots are an extension of our voices and we’re asking the court to ensure that every person has the right to make theirs heard,” California Attorney General Rob Bonta said in a statement announcing the lawsuit.

Also on Wednesday, a federal judge lifted a major obstacle to President Donald Trump’s executive order limiting mail voting, but the decision will only clear the path for more legal challenges.

On Friday, the USPS released a rule that requires states to collect basic voter information, such as a person’s name and home address, and enter it into a federal ballot mail portal before it can be accepted by the mail service.

The amendment to the mailing standards of the agency regarding the transmission of mail-in or absentee ballots for federal elections requires a unique barcode for every mail-in ballot that is distributed but does not authorize the inspection of ballots’ contents, review of voters’ eligibility or auditing of state voter rolls, the agency said.

The rule follows an executive order Trump signed in March, titled “Ensuring Citizenship Verification and Integrity in Federal Elections,” which directed the Department of Homeland Security, in partnership with the Social Security Administration, to develop an approved list of mail-in and absentee voters. It also directed the USPS to only send mail-in ballots to voters on the list and ordered U.S. attorney general to investigate ballots it deemed to be wrongfully distributed.

Wednesday’s lawsuit is the second that the coalition of Democratic state attorneys general have filed against the Trump administration over the executive order. Their first was filed in April, resulting in a temporary injunction to prevent any changes to mail-in ballots while the lawsuit continues.

While the new USPS rule said the Postal Service “will not take actions to implement the rule specifically for the 2026 election unless and until the government obtains relief from those injunctions,” it said it would mmediately implement the new rule if the injunctions are lifted.

On Monday, the Supreme Court granted the Trump administration’s emergency request to temporarily pause the injunction that had blocked some provisions of the executive order from being implemented before the November elections in the 23 states that filed the prior lawsuit, saying the states had filed their challenge too early. The ruling said the coalition can still challenge the USPS rule, which is what the new lawsuit seeks to do.

In addition to the lawsuit, the AG coalition said it is filing a motion for a temporary restraining order and a preliminary injunction to block the rule from being implemented while the lawsuit continues.

The USPS did not respond to a request for comment about the new lawsuit before this story was published.

U.S. District Judge Indira Talwani in Boston, an appointee of former Democratic President Barack Obama, agreed Wednesday to remove her previous injunction that prohibited the Postal Service from carrying out Trump’s order for November’s elections. Talwani said the Supreme Court’s Monday decision “compelled” her to toss out the injunction.

On Tuesday, Talwani ruled that the Trump administration violated her previous order, but she did not sanction it.

Bonta co-led Wednesday’s lawsuit with the attorneys general for Massachusetts, Nevada and Washington. Arizona, Colorado, Connecticut, Delaware, the District of Columbia, Hawaii, Illinois, Maine, Maryland, Michigan, Minnesota, New Jersey, New Mexico, New York, North Carolina, Oregon, Rhode Island, Vermont, Virginia, Wisconsin and the governor of Pennsylvania are also parties to the litigation.
