It is a long-established principle that presidential impeachment is an appropriate remedy only for “high Crimes and Misdemeanors” of a public nature (with the possible exception of private crimes so heinous that the President “cannot be permitted to remain at large”). The crux of this Essay's argument is that the President's affair with Monica Lewinsky was a private matter that was not rendered “public” simply because Mr. Clinton lied about it. With its vote against removing the President, the Senate seemed to agree.
