Re: To be honest ...
Er... impeached, but not convicted, in that case. No US president has been impeached and convicted, so none has been removed by impeachment.
Johnson was found guilty by a majority but it fell a vote short of conviction. Clinton was found not guilty by a small majority on one charge; the vote was split 50/50 on the second. You know what happened with Trump.
Nixon resigned before he could be impeached.
