Federal prosecutors investigating former President Donald J. Trump’s handling of classified material have a recording of Mr. Trump from 2021 discussing a sensitive military document he had kept after leaving the White House, two people briefed on the matter said.
In the recording, Mr. Trump suggested he knew the document was secret and had not declassified it, one person briefed on the matter said.
The existence of the recording could undermine Mr. Trump’s repeated claim that he had already declassified material that remained in his possession after he left office. Prosecutors are scrutinizing whether Mr. Trump obstructed efforts by federal officials to retrieve documents he took with him after leaving office and whether he violated laws governing the handling of classified material.
