Democratic States Sue Over Trump's Mail-In Voting Order

Two dozen Democratic-led US states have filed a lawsuit to stop the postal service from following part of President Trump's mail-in voting order.

Mail-in voting allows people to send their vote through the post instead of going to a voting location in person.

The lawsuit was filed just days after the supreme court lifted an injunction that had been blocking part of Trump's order.

An injunction is a court decision that temporarily stops an action from taking place until a further ruling is made.

By lifting the injunction, the supreme court allowed the blocked part of the order to move forward again.

The states, which are led by Democratic officials, disagree with how the order affects mail-in ballots handled by the postal service.

The Democratic Party is one of the two main political parties in the United States.

The postal service is the government agency responsible for delivering mail, including ballots sent by voters.

A ballot is the official paper or form that a person uses to cast their vote.

The states are asking the courts to step in again and stop the postal service from carrying out this part of the order.

This dispute is part of a wider ongoing disagreement between Trump's administration and Democratic-led states over how elections are run.

Elections are the process by which citizens choose their leaders through voting.

The case is expected to continue moving through the courts, and further rulings may follow in the coming days.
