Democratic state attorneys general are seeking to block President Donald Trump’s proposal for an overhaul of U.S. elections in a case that tests a constitutional bedrock — the separation of powers.

A federal judge appeared open on Friday to blocking enforcement of U.S. President Donald Trump's sweeping executive order overhauling elections that calls for requiring voters to prove they are U.S. citizens and barring states from counting mail-in ballots received after Election Day.

A federal appeals court on Friday ruled that the Trump administration may ban the Associated Press from the Oval Office and other limited spaces for now, pausing a judge’s order to return the wire service’s access.
