"Well, here we go again. Markwayne Mullin proving that common sense isn't so common in Washington. The guy literally challenged a witness to a fistfight during a Senate hearing. What kind of example is that for our kids? Meanwhile, our roads are crumbling and gas prices are through the roof. Maybe focus on fixing the potholes instead of flexing your biceps in a suit, Mr. Mullin. This isn't a wrestling ring, it's a committee room. Absolute embarrassment for Oklahoma."
