A federal judge has temporarily blocked the US Postal Service from carrying out a plan that could limit mail-in voting. The judge's order was sought by Democratic states and voter advocacy groups challenging the Trump administration's guidelines for the US Postal Service.

The plan in question involves the US Postal Service's refusal to send mail-in ballots to eligible voters unless states or local election officials submit their ballot envelopes and return envelopes for approval.

Further details about the case and the judge's order are available from the source, including the specific ruling and its implications for the upcoming election.
