There is a very short video (a couple of seconds is what I've heard, though I have not sought nor viewed it) in which Tim Walz holds Gus by the arm and takes Gus off-stage. I've criticism of it, and I've heard comments to the effect that what he did is not unusual for parents and caretakers of neuro-divergent kids, both from conservative people. The latter POV I heard from parents with experience with such kids, so I'm inclined to believe them.
