"Oh yes how dare people yell things out at JA while he is trying to do his job…oh wait. Isn't it JA who routinely yells stuff at the President while he is doing his job? Hmmm."
Great advice-spend travel time condensing your possible on air message to a 5-7 second sound bite. If you are asked another question or given more time, restate your core message. If you are with others, they should do the same with their core message or reemphasize what you say.
Be pithy–no bloviating.
Leastwise, that was the training I got.
