Only Trump, however, has been pursued prosecutorially after leaving office
Three Presidents have been criminally investigated while in office, Richard Nixon, Bill Clinton, and Donald Trump. Only Trump, however, has been pursued prosecutorially after leaving office. Nixon would have been, one might suggest, but about a month after taking office President Gerald Ford pardoned Nixon, granting, “a full, free, and absolute pardon…for all offenses against the United States…committed or may have committed or taken part in.” The pardon likely saved Nixon from protracted and expensive legal battles that would have likely never found impartial juries.
The United States Constitution, the Supreme Law of the Land, is where the real hammer against going after a President lies. At the end of Article I, Section 3 the Constitution discusses punishment for conviction of impeachment, and the language provided is clear:
Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States; but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law.
Impeachment is a political trial. If an individual is convicted of an impeachment, they are not walked out of office in handcuffs and an orange jumpsuit. According to the clause in Article I, Section 3 of the United States Constitution the worse punishment if convicted by impeachment is removal from office and the inability to hold office ever again.
