Evan Mecham was impeached in the early 90's. He was removed from office.

There was also a Recall Drive. They had enough petition signatures for a Recall, but the Impeachment beat them to it.
Evan Mecham's 1986 election with about 35% of the vote was the inspiration for a new law requiring a run-off election if the candidates didn't get 50%+1, and that law went away after a couple of election cycles.
Later, there was a criminal case, but all the evidence was despoiled by the Dems' Impeachment trial and he was acquitted.
