As more information has emerged in the days since FBI agents combed the former President’s private residence, current administration officials have become increasingly concerned about what Trump took and whether that information — some located in a basement-level storage facility at Mar-a-Lago — could potentially put the sources and methods of the US intelligence community at risk.

“There is a deep concern,” one senior administration official told CNN.

Intelligence officials have also expressed concern about what Trump might have taken, according to a source with direct knowledge of the matter. Intelligence community representatives have had discussions with the Justice Department, congressional intelligence committees, and the National Archives in recent months about potentially missing sensitive documents, the source said.
