Unlike his counterpart, Special Counsel Jack Smith, who has been aggressively prosecuting former president Donald Trump, Hur has virtually disappeared since his appointment to investigate President Joe Biden. Hur surfaced to interview Biden over his possession of classified documents, including some that go back to his time as a U.S. senator.

I have referred to Hur as a "neutron prosecutor" — a special counsel with no possible charge, under Justice Department policy barring the indictment of a sitting president. If that was not enough of a problem, Hur may have growing evidence that accounts offered by the White House over the discovery of the documents are false.

The new evidence could prove transformative, not only for the criminal but the impeachment investigation of the president.

This week, the House Oversight Committee released a new timeline on the discovery of classified documents in various locations associated with Biden. From the outset, many of us flagged problems with the account that had been given by Biden, who insisted that he had no knowledge or involvement in the removal or use of the documents.

The most glaring problem is that, after they were removed at the end of his term as vice president, the documents were repeatedly moved and divided up. Some were found in the Penn Center office used by Biden in Washington, D.C. Others were found in his garage and reportedly in his library. 

Biden made clear from the beginning that he expected the investigation to be perfunctory and brief. He publicly declared that he has "no regrets" over his own conduct and told the public that the documents investigation would soon peter out when it determined that "there is no 'there' there."
