Impeachment Conviction is the removal, and no Presidents have been subjected to an Impeachment Conviction.
Disagree. Impeachment is a process possessing both the bringing up of charges and removal upon conviction: a process with two major elements.
The writers of the Constitution included both elements in the context delegating the initiating element to one body and the concluding element to a separate body. If they had left out one or the other element, the process would have been meaningless and therefore omitted.
