-- I believe Comey would come under the heading of "inferior officer" which doesn't require Congressional impeachment and removal. --

Does Congress have the power to impeach and remove the Director of the FBI? If so, the Director of the FBI is subject to impeachment and removal by Congress; and can be removed by the president.

Does the president have the power to fire the Attorney General?

FWIW, the line between "inferior" and "superior" is a little murky. But I take your positions as:

• Superior officers cannot be (constitutionally) removed from office except by impeachment and conviction.
• It is unconstitutional for the executive branch to investigate a superior officer for criminal wrongdoing.
• Only Congress may take legal action against a superior officer, see Article I impeachment, trial, penalty on conviction.

I think your summary of my positions look pretty accurate and fall in line with the text of relevant constitutional clauses “cited”.
