 We're talking to Dr. Ronny Jackson, congressman from Texas, also was the White House medical doctor, know him very well, was on a lot of Secret Service advances. Doc, you just said something. When he mentions a walkthrough, by the way, folks, what happens is when the advance is done and the plan is relatively complete, a Secret Service supervisor and some supervisors from the military, they'll come in and we'll do a walkthrough. Well, we'll basically walk through the event in exactly the footsteps the president would take. And sometimes you notice stuff. And the doc here, the good doctor, just said something, which is interesting.
