* The press secretary (or President, or whoever) makes a statement
* He or she chooses a journalist to ask a question
* Journalist asks question
* Press secretary answers question in as much or as little detail as he/she wants
* Press secretary calls another journalist
* This goes on for maybe 20-30 minutes, and it's over.
How does this even help at all? It's not like the press secretary is going to answer a question that he/she doesn't want to answer anyway.
