Doesn’t Comey serve at the pleasure of the sitting President?
He can be terminated for cause. What constitutes cause is a political question the courts won’t touch. So yes he can be fired.
DJT could have fired Comey right after his inauguration, but he didn’t.
Why?
He’s appointed FOR a 10 year term, and can be re-appointed, I presume... but there is no language that says he cannot be fired or impeached.
Even Supreme Court judges can be gotten rid of
