So rather than merely pardoning his son for the gun crimes for which he was convicted and the tax crimes for which he pleaded guilty, the president’s pardon covers all “offenses against the United States which he has committed or may have committed or taken part in” from Jan. 1, 2014, through Dec. 1, 2024. That language mirrors the language in Ford’s pardon of Nixon, which did not merely cover the Watergate scandal but extended to “all offenses against the United States” that Nixon “has committed or may have committed” between Jan. 20, 1969, and Aug. 9, 1974 — the exact span of Nixon’s presidency.
