“Disclosure of the government’s affidavit at this stage would also likely chill future cooperation by witnesses whose assistance may be sought as this investigation progresses, as well as in other high-profile investigations,” the Justice Department wrote. “The fact that this investigation implicates highly classified materials further underscores the need to protect the integrity of the investigation and exacerbates the potential harm if information is disclosed to the public prematurely or improperly.”
The DOJ said details in the affidavit that lay out the argument that investigators made to Federal Magistrate Judge Bruce Reinhart explaining the probable cause it had to search Trump’s Mar-a-Lago estate last week. The search, documents show, was an evidence-gathering step in a national security investigation about presidential records at Mar-a-Lago. Trump owns the sprawling estate, and it is his primary residence as well as a members-only club and resort.
