In a stark repudiation of Donald Trump’s legal arguments, a federal appeals court on Wednesday permitted the Justice Department to resume its use of classified records seized from the former president’s Florida estate as part of its ongoing criminal investigation.

The ruling from a three-judge panel of the U.S. Court of Appeals for the 11th Circuit amounts to an overwhelming victory for the Justice Department, clearing the way for investigators to continue scrutinising the documents as they consider whether to bring criminal charges over the storage of top-secret records at Mar-a-Lago after Trump left the White House. In lifting a hold on a core aspect of the department’s probe, the court removed an obstacle that could have delayed the investigation by weeks.
