A top Justice Department official told former President Donald J. Trump’s lawyers in recent weeks that the department believed he had not returned all the documents he took when he left the White House, according to two people briefed on the matter.
The outreach from the official, Jay I. Bratt, who leads the department’s counterintelligence operations, is the most concrete indication yet that investigators remain skeptical that Mr. Trump has been fully cooperative in their efforts to recover documents the former president was supposed to have turned over to the National Archives at the end of his term.
It is not clear what steps the Justice Department might take to retrieve any material it thinks Mr. Trump still holds.
