Brennan’s answer to Gowdy’s inquiry demonstrates that he was caught off off guard and unprepared to respond.
Yep - Gowdy obviously knows something and Brennan realized that as he stuttered his “I kinda sorta don’t really recall such” and it was obvious he was a bit nervous with the question and the way it was posed. I think Gowdy may finally redeem himself in the eyes of those who keep slamming him for not doing things he didn’t have the power to do - his teeth are in full bite mode.
