HADLEY interview on NPR

Why should NPR have run out of time interviewing Stephen HADLEY, the National Security Advisor, about Iran two days ago? Shouldn't we expect NPR to change its schedule when there is something as important as this with someone as close to the "action" as is HADLEY? I would expect NPR to do this, and - perhaps most surprising - I would have thought that they would have continued the interview off air but on line if that was the only option. To do less than that, as was the case, is a big disappointment.
