Can a president still be impeached after he/she leaves office?

Question

as wikipedia points out (so it must be true:-) A typical misconception is to confuse it with involuntary removal from office; in fact, it is only a legal statement of charges, paralleling an indictment in criminal law.

Answer 1

wikipedia is the WEAKEST source

Answer 2

No, he can't.

Impeachment simply causes removal from office.

Once out of office, he can't be removed again.

Answer 3

I take the info from wikipedia as a grain of salt. you need a relaible source.

Stop hating on the president.
