A search of documents taken to Mr. Biden’s house in Delaware later turned up several more such documents, and in January Attorney General Merrick B. Garland appointed Mr. Hur, a former Trump-era U.S. attorney for Maryland, as a special counsel — a prosecutor with a degree of day-to-day autonomy to handle sensitive investigations — to investigate the matter.
The inquiry has played out against the charged backdrop of another special counsel investigation, into former President Donald J. Trump’s handling of classified documents he took to his Florida club and residence, Mar-a-Lago, and his refusal to give them all back even after being subpoenaed for them.
The prosecutor in that case, Jack Smith, has charged Mr. Trump with unauthorized retention of national security secrets and obstruction, among other counts. By contrast, Mr. Biden’s team has sought to portray itself as being completely cooperative with the investigation.
Mr. Hur’s investigation has played out relatively quietly. Unlike Mr. Trump’s case, there have been no known fights before a grand jury over claims of executive privilege. But Mr. Hur appears to have been exhaustively interviewing everyone with a line of sight onto how the documents were packed up and moved, as well as how Mr. Biden’s team handled their discovery.
In his statement, Mr. Sams said little more, referring further questions to the Justice Department, which has consistently declined to comment on substance of the inquiry.
