WASHINGTON — A federal judge on Monday permanently barred the release of a report by special counsel Jack Smith on his investigation into President Donald Trump’s hoarding of classified documents, a prosecution that was once seen as the most perilous of the four criminal cases the Republican faced.

U.S. District Judge Aileen Cannon, who was nominated to the bench by Trump, granted a request from the president to keep under wraps the report on an investigation alleging that Trump stored sensitive documents at his Mar-a-Lago estate after he left the White House following his first term and that he obstructed government efforts to get them back.

Smith and his team produced a two-volume report on the classified documents investigation and a separate probe into Trump’s efforts to overturn the 2020 presidential election after he lost to Democrat Joe Biden. Both investigations produced indictments that were abandoned by Smith’s team after Trump’s November 2024 election win in light of longstanding Justice Department legal opinions that say sitting presidents cannot face federal prosecution.

Attorney General Pam Bondi had already determined that the report was “an internal deliberative communication that is privileged and confidential and should not be released” outside the Justice Department, according to court papers. The Trump administration has characterized Smith’s investigation as politically motivated and said in recent court papers that the report belongs in the “dustbin of history.”

Cannon’s order blocking the release also applies to Bondi’s successors at the Justice Department. Cannon, who in 2024 dismissed the case after concluding that Smith was unlawfully appointed after multiple other favorable rulings for Trump, said the release of the report would present a “manifest injustice” to the president and his two co-defendants.

“Special Counsel Smith, acting without lawful authority, obtained an indictment in this action and initiated proceedings that resulted in a final order of dismissal of all charges,” she wrote. “As a result, the former defendants in this case, like any other defendant in this situation, still enjoy the presumption of innocence held sacrosanct in our constitutional order.”

Chioma Chukwu, executive director of American Oversight, said it “will continue using every tool available to force this information into the open and to defend the public’s right to the truth through the release of this report.”
