What happens if Trump committed treason? [duplicate]

Question

According to the NYTimes post "There’s a Smell of Treason in the Air",

Now the F.B.I. confirms that we have had an investigation underway for eight months into whether another presidential campaign colluded with a foreign power so as to win an election. To me, that, too, would amount to treason.

If treason is confirmed and Trump were to be ousted as POTUS, would that apply to all those in his party/administration or that he appointed during his illegitimate time making such decisions?

• If the answer is no, then I don't understand how it works and "common sense" would tell me it'd not benefit deterring future corruption at this level (of a whole political party) otherwise if the VP took over as POTUS and everything else the illegitimate POTUS did or appointed at his sole discretion stayed the same. If he's a treasonist, then don't leave those in office positions he appointed or if he had great influence in getting them there.

Answer 1

In the hypothetical situation that a president's election were found to have been effected by treasonous acts, it would be too complicated to nullify everything that president had achieved while in office. More to the point, there is no constitutional mechanism for doing it. Conviction on articles of impeachment ends a president's tenure in the office; it doesn't undo the election.

Instead, it would be for the president's successor to undo any executive actions deemed to be tainted by the treason, and it would be for Congress and the new president to repeal any laws, just as it is when any president leaves office. Similarly, any judicial appointments tainted by the treason would have to be undone with separate impeachment proceedings brought against the judges or justices in question.

As to the deterrent, if the vice president were also implicated in the treason, then the vice president would also be subject to impeachment and conviction. Perhaps this could be done concurrently with the president, allowing the speaker of the House of Representatives to assume the presidency. But if the whole government is involved, then really all you can do is wait until the next election, or get the states to call a constitutional convention.
