Article 2, Section 4 of the US Constitution states:
The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.
This clause apparently lays out the requirements for removing a US Office, and requires that the Officer being impeached commit "treason, bribery, or other high crimes and misdemeanors".
Does that clause mean that that the FULL EXTENT AND LIMIT of impeachable offenses are those listed?
For example suppose a Party managed to gain control of 2/3 of the Senate and the House and they decided to impeach a sitting President of another Party for purely political purposes. I.e. the President did nothing, but the Congress impeached anyway, or the Congress invented some specious charge to justify the impeachment.
In that case could the Supreme Court overturn an Impeachment?
