Sources Thiessen talked to, however, argued that the process of engaging with intelligence briefers couldn’t “be replicated on paper.”
“According to former officials who have detailed knowledge of the PDB process, having the daily meeting — and not just reading the briefing book — is enormously important both for the president and those who prepare the brief,” Thiessen wrote.
“For the president, the meeting is an opportunity to ask questions of the briefers, probe assumptions and request additional information. For those preparing the brief, meeting with the president on a daily basis gives them vital, direct feedback from the commander in chief about what is on his mind, how they can be more responsive to his needs, and what information he may have to feed back into the intelligence process. This process cannot be replicated on paper.”
