If they zing him enough, maybe he will lose it. If he trips...he falls.
Unfortunately, the procedure of these hearings doesn’t lend itself to the likelihood of that happening.
5 minutes Repub, 5 minutes of Dem softball, duck and cover defense. Nearly useless.
Now, if they arranged it to give 3 Repub members-— say, Issa, Burton, Chaffetz.... we might get somewhere. :-)
