FBI Director James Comey once said this:
I James Comey do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies,
foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation
or purpose of evasion; and that I will well and
faithfully discharge the duties of the office on which I am about to enter.
So help me God.
