22 but that last one is also a trick question, they were never actually kicked out of office! 
No trick. Impeachment is a big word (politically speaking), but it just means indictment. As well as the fact that the Congress thinks you are a crook. The standard is preponderance of the evidence. Conviction (in the Senate) means you're gone. That requires proof beyond a reasonable doubt. The Constitution doesn't spell this out, but its the way its been interpreted through a fair few numbers of lesser office holders. The idea is that any decent politician, judge or whomever would resign after being impeached, or "take the honorable way out". No such luck here.
