Not for a Presidential appearance.
-PJ
I’ve given my share of presentations too and the only one who “reviewed” my slide show ahead of time was me. This was put on by a bunch of college kids, not a major corporation that has people to review and double check to make sure that the presentation was in line with corporate interests.
I’ve also been at a number of events involving the secret service in a variety of contexts, they focus on the President’s safety, not whether a student is going to put a practical joke image on a laptop or thumb drive. That’s not their job.
