> “If I did something wrong,” Brennan continued in March, “I will go to the president, and I will explain to him exactly what I did, and what the findings were. And he is the one who can ask me to stay or to go.”
Notice how brazen they are. "I didn't do anything, but even if I did, I'd have to be the one determining that. And even then, there is nothing you can do about it, since I work for the President and only he can fire me".
That was n 2014 and Brennan was in office till 2017.
