President Donald Trump on Tuesday signed a memorandum directing the immediate declassification of all FBI files related to the controversial Crossfire Hurricane investigation.

The probe, which Trump has repeatedly criticized as politically motivated and corrupt, centered on alleged ties between his 2016 campaign and Russian officials.

White House Staff Secretary Will Scharf confirmed the directive, which mandates federal agencies release all documents tied to the 2016 investigation. Trump described the investigation as “total weaponization” and a “disgrace,” adding that the documents would now be declassified for public scrutiny. He criticized the FBI and Department of Justice for their actions, calling the investigation a hoax.

The investigation, launched during the Obama administration, was aimed at determining Russian interference in the 2016 election but failed to uncover evidence of criminal conspiracy. Trump also pardoned Devon Archer, a former business associate of Hunter Biden, who had testified about the Biden family’s overseas dealings.
