I appreciate your theory, but I don’t think trump found out anything or would remotely care. He’s so dementia addled, this guy’s execution was no more than jangly keys for a moment, and he couldn’t even tell you the guy’s name. He doesn’t even know the guy is in a wheelchair, because that would require more than a fleeting glance at what’s going on.
Ask him later today and he’ll have forgot this guy exists at all. It’s some dude who doesn’t matter at all because he’s not an investor or his daughter. Trump’s brain is literally Swiss cheese at this point. The people around him may be oppressing the disabled, but trump can’t because he’s forgot they exist at all.
