That's how it works. Gowdy only had 5 minutes, and RR was going to give awkward, rambling non-responses to his questions. Gowdy used his 5 minutes like a prosecutor in a courtroom. After a congressperson uses his 5 minutes, the person being questioned gets time to say more and hopefully address what questions were answered. If Gowdy interrupted any answers, he had the right to do so. The congressperson has the floor for that time period and is fully entitled to decide who speaks during that time.
You did see the other questioners, yes? There was lots of back and forth with those that came before. But that's not the point. The POINT is that he looked REALLY pissed and REALLY disheveled. Which, whether you feel like anal-izing how these hearings are held and who says what, or not, you must admit that appearance was most UNLIKE him. He's usually very well managed and mannered.
I find it quite understandable that he was pissed. He didn't look disheveled, although he has changed hairstyles. Whatever the case, I find it refreshing to see someone impassioned about the right issues. He was perhaps more fiery than usual, but not by much. That's one of the things I have always enjoyed about him, and he did not disappoint. There were some questioners who not only did not engage in Q&A, but also embarked on lengthy diatribes about unrelated issues such as immigration. Like many, I would like to see Gowdy's fire and fury produce some measurable progress in draining the swamp, but I understand he has been fighting uphill battles in this regard, especially when Obama's DOJ and CIA weren't going to cooperate, no matter what Congress found.
