[Source: Reuters]A federal appeals court on Saturday declined to allow U.S. President Donald Trump’s administration to implement in ​23 states his executive order that aims to tighten rules for mail-in voting ahead of November elections that will decide control of Congress. The ‌Boston-based 1st U.S. Circuit Court of Appeals rejected the administration’s request to lift an injunction several Democratic-led states secured on June 25 from a lower-court judge who concluded that key parts of the Republican president’s order were unconstitutional. The ​appeals court, in a 2-1 ruling, rejected that argument. “The Plaintiff ​States have no practical choice but to respond to the (order) now.”‘
