speaking on hypotheticals

let's say that through investigation there is found to be conclusive evidence that there was treasonous collusion between the current administration and foreign entities

everyone is talking about impeachment but would there also be another 'emergency', or expedited, general election?

it would seem to me that if trump were to be removed then the entire cabinet and all of its subsequent decisions would need to be removed as well

pence, gorsuch, any bills and executive orders

these would in effect be policy and decisions made under treasonous intent and by an administration being led on by foreign entities so should be treated as such
