First of all, Mr. Chair and Mr. Comartin, let me apologize for that incident. That's unacceptable.
Our members should have.... Again, once the visit has ended and perimeters are down, there's free access, so that should not have occurred.
With respect to why they were still there, that's a good question. Again, depending upon the circumstances and the timing of when the motorcade departed, we usually, for different reasons, keep the site secure upon departure, and then we stand down our members.
