Mitch Rapp and Politicians
In the books Thomas Stansfield and Irene Kennedy began bringing Mitch to briefings because they recognize he had an ability to cut through all the BS and wasn't afraid to go head to head with politicians and senators. Mitch was politicaly lethal. More and more politicians began to realize that to go up against Mitch Rapp was a good way to get their careers ended.
I hope they at least set the stage for this side of Mitch. It's what makes him such a unique person, no matter what situation he faces when he knows he is right he is fearless and will not compromise.
