Hello and welcome to the US politics live blog.

A second ⁠federal ⁠judge has prevented ⁠Donald Trump’s administration from implementing ⁠a ​new ‌US ‌Postal Service ‌rule that would tighten mail-in voting requirements.

However, ‌the US Supreme Court is ​still weighing the administration’s ⁠request to ​overturn a separate ​order ​blocking the ​rule. Late on Sunday, District Judge Carl J Nichols in Washington, DC, handed down a similar hold on the rule, which was issued 21 August.

“Plaintiffs have demonstrated that, absent an injunction, there is an increased risk that a significant number of otherwise appropriate absentee or mail-in ballots will ultimately not be counted in the upcoming elections,” Nichols wrote in issuing the preliminary injunction.

“The public has a strong interest in ensuring that doesn’t happen.”

Nichols in May had refused to issue an injunction because he ruled the lawsuit seeking one was brought too early. That was the high court’s reasoning late last month when it lifted an earlier freeze by Talwani.

But because the administration had just issued its rule to move ahead with Trump’s plan, the plaintiffs in Boston and Washington, DC, refiled their lawsuits. Talwani was nominated by former president Barack Obama and Nichols was nominated by Trump.

The new Postal Service regulations stem from an executive order Trump issued earlier this year. Election officials say it would be impossible to implement the changes this close to a general election.

In other developments:

• Trump on Sunday called on Ukrainian president Volodymyr Zelenskyy to halt strikes on Russian oil refineries and other infrastructure used to produce and distribute diesel, saying the attacks are causing a global shortage. He spoke after diesel prices in the US hit a record on Friday, soaring past $6 a gallon on average.

• British ministers face calls to act after US authorities secretly flew out of the UK a diplomat accused of possessing indecent images of children. US officials reportedly raided the diplomat’s London flat in August before taking him to an American airbase and flying him out of the country, without warning the Metropolitan police.

• A newly unveiled statue of the rightwing activist Charlie Kirk was vandalized at the Turning Point USA headquarters in Phoenix, Arizona. The statue was found with red spray-paint. A nearby poster memorial in front of the statue was vandalized with red paint as well.

• A coroner in Pennsylvania announced the death of a 40-year-old woman associated with the state’s ongoing measles outbreak. The death appears to mark the third in the US state’s ongoing outbreak. Two previous deaths in the state were in infant children. In one case, the infant was born with a genetic defect that made her vulnerable to infection. The second infant child was infected with measles, and died of a ruptured spleen.

• A Republican congressman said he had to swim to safety after a plane he was traveling in made an emergency landing in a lake late Saturday. Representative Tom Tiffany says he was returning from the La Crosse county Lincoln Day Dinner when the light aircraft lost power as it approached Wausau downtown airport. The pilot made an emergency landing in Lake Wausau. They both ended up in the water and swam to safety.

• Barack Obama urged Democrats to prioritize a “public conversation” about AI management and safety in a closed-door Manhattan fundraiser last week. The comments by the former US president reportedly urged the party to create a sweeping framework for everything from a safety “slow-down” to domestic job losses and children’s wellbeing.
