President Donald Trump has thrown the Justice Department’s Jan. 6 Capitol riot prosecutions out the window. But a week before Trump became president, the Department essentially did the same to its own investigation of Trump. The Department’s hand-picked Trump prosecutor, Jack Smith, quit and released a report on the investigation that resulted in the indictment of Trump on four counts involving the 2020 election and Jan. 6. The report did not have a lot of new information in it — Smith has poured out his evidence in filing after filing for more than a year — but it did contain Smith’s assessment that he could have convicted Trump had Trump not won the presidency and is thus no longer subject to federal prosecution.
