Get over it.
The hearing is not over until Cummings gets to put in his 2 cents worth for the TV cameras. Assholes like Cummings live for these moments. John McCain is similar. The older they get the more vain they get. The more they love the TV cameras
Cummings blew up because he had his little prepared speech for the TV cameras and Issa cut off his mike. POS Cumming had been waiting for weeks for this moment.
