Ever wonder how White House Press Secretary Jay Carney determines how long his daily press briefings go?
Typically it's not his decision to make.
Tradition dictates that a press briefing reaches its conclusion only after the senior wire reporter in the room says "thank you" to the press secretary.
If you look at the transcripts, you will notice the final question, while not always, is often simply a "thanks" to the briefer – unless the press secretary voluntarily decides to take on more grilling.
