@SW-User No President has ever been removed from office. Not because they were innocent but because it makes the country look bad.
Imagine the loss of credibility we suffer if Congress declares the President is a crook and convicts them. No one would cut deals with us or believe us again.
So the way Presidential politics works is no President is removed by Congress. They may get impeached but what actually happens is Congress puts a halt to their agenda.
@SW-User Well Nixon would have been removed if it came to that. He knew neither he nor the country could survive the embarrassment. But that's only because he was exposed by the media and the evidence provided to the public. That's the one time the evidence got into the hands of the public.
