The Constitution limits grounds of impeachment to "Treason, Bribery, or other high Crimes and Misdemeanors".
[2] The precise meaning of the phrase "high Crimes and Misdemeanors" is not defined in the Constitution itself.
The notion that only criminal conduct can constitute sufficient grounds for impeachment does not comport with either the views of the founders or with historical practice.[1] Alexander Hamilton, in Federalist 65, described impeachable offenses as arising from "the misconduct of public men, or in other words from the abuse or violation of some public trust."
[3] Such offenses were "
political, as they relate chiefly to injuries done immediately to the society itself."
[3] According to this reasoning, impeachable conduct could include behavior that violates an official's duty to the country, even if such conduct is not necessarily a prosecutable offense. Indeed, in the past both houses of Congress have given the phrase "high Crimes and Misdemeanors" a broad reading, finding that impeachable offenses need not be limited to criminal conduct.
