I remember hearing a story about a Senator who cast the deciding vote not to impeach Andrew Johnson, even though he despised Andrew Johnson, because he didn't think Johnson was guilty and it would set a bad precedent. In the story I heard, he was deathly ill but was brought back to Congress just to make this vote.
I did a search and could not find any evidence that this ever happened. I started to think that maybe it had nothing to do with Andrew Johnson and that I'm confusing different stories, because Johnson avoided being impeached by a single vote.
Anybody know what I'm talking about?
