In late April, the source says, a federal grand jury began deliberating whether there was a violation of the Presidential Records Act or whether President Trump unlawfully possessed national security information. Through the grand jury process, the National Archives provided federal prosecutors with copies of the documents received from former President Trump in January 2022. The grand jury concluded that there had been a violation of the law, according to the Justice Department source.

In the past week, the prosecutor in the case and local Assistant U.S. Attorney went to Florida magistrate Judge Bruce Reinhart in West Palm Beach to seek approval for the search of Donald Trump's private residence. The affidavit to obtain the search warrant, the intelligence source says, contained abundant and persuasive detail that Trump continued to possess the relevant records in violation of federal law, and that investigators had sufficient information to prove that those records were located at Mar-a-Lago—including the detail that they were contained in a specific safe in a specific room.
