The Justice Department’s special counsel investigating President Biden’s handling of classified documents has concluded his investigation and a report is expected to be released to Congress and the public soon, Atty. Gen. Merrick Garland told lawmakers in a letter Wednesday.

Garland did not provide details on the conclusions of special counsel Robert Hur’s report, but said he was committed to making as much of the document public as possible once the White House completes an investigation into possible concerns about executive privilege.

The yearlong investigation focused on Biden’s unlawful retention of classified documents from his time as a U.S. senator and as vice president. Documents were found in his Delaware home and in a private office he used between his service in the Obama administration and his presidency.

Garland appointed Hur, a former U.S. attorney for Maryland during the Trump administration, to handle the politically sensitive investigation, while another special counsel conducted a separate investigation into former President Trump’s storage of classified documents at his Mar. estate -a-Lago in Florida. The dual appointments were seen as a way to protect the Justice Department from claims of bias or conflict of interest.

The Trump investigation resulted in dozens of charges against the ex-president last year

including intentional retention of secret documents and conspiracy to pervert the course of justice

The outcome of the Biden investigation is expected to be different. Justice Department policy prohibits charges against a sitting president, and unlike the Trump investigation, no evidence has publicly emerged of a deliberate mishandling of government secrets or an attempt to prevent the return of classified documents.

The investigation’s looming conclusion was foretold last fall when Biden sat down with Hur’s team for a voluntary interview at the White House. Interviews with important topics in a study often take place towards the end.
