A federal appeals court in Boston has rejected President Donald Trump's administration's attempt to implement an executive order aimed at tightening mail-in voting rules across 23 states ahead of the November elections.

The 1st Circuit Court of Appeals ruled 2-1 against the Department of Justice's request to lift an injunction imposed by a lower court, which found key parts of Trump's order unconstitutional.

The court emphasized that states must comply with the order's deadlines while ensuring voters understand the rules, leaving no practical choice but to respond immediately.The decision comes after a similar effort by Democrats to block the order was also rejected by a Washington, D.C.judge.

Trump's executive order, signed in March, directed federal agencies to compile citizenship lists and restrict ballot delivery, but judges have consistently blocked his attempts to overhaul election procedures.

The ruling underscores the legal challenges facing Trump's efforts to influence voting rules, with critics arguing the order seeks to intimidate election officials and suppress voter access.
