 when we talk about the Secret Service and what happened and didn't happen. And I thought about you, and I want to sort of close on this, because you have been in those, thankfully not in a situation exactly like Saturday, but you've had to prepare for those before. Anytime you were anywhere with the president as chief of staff, you were outside at events at times, and you had to know what to do, and you know what the Secret Service is required to do in those situations. So what do you make of that?
