New details have emerged about minders who sat in on 9/11 Commission interviews during a fact-finding trip to Canada. Commission heads Tom Kean and Lee Hamilton mentioned the minders generally in interviews during the panel’s lifetime, but a memo recently found in the National Archives and blogged here a couple of weeks ago showed how prevalent they were.

Another document, again found by History Commons contributor paxvector, provides more details of how the minders worked during a trip to Canada. The commission, which eventually recommended taking part of the CIA director’s responsibilities away and giving them to a Director of National Intelligence, was considering changes to the intelligence community and sent a team to Canada to examine how its intelligence services were organised and report back.
