There is a code/keypad lock on the camera feed. IIRC, when the revolt began, the cameras came back up shortly after then went down because (I think it was) Rep. Shadegg just at random hit the correct sequence of keys for the camera feed to go back live.
The Speaker of the House controls the camera access to the chamber, and MADAME does not want the "great unwashed" to have news of the revolution. No one else can turn the feed back on legally (and the Dem Speaker has the code/control physically). MADAME Pelosi wants $5 a gallon gas as a means of enviro-nazi social engineering. Folks won't be able to afford gas therefore consumption (in her mind pollution) goes down. Typical limousine liberal's "Let them eat cake" attitude.
You’re right, it was Shadegg. He was having a blast friday saying it’s usually boring but this was a kick. lol
