If anything, CNN tried to mitigate his freezes by “cutting him off” when he locked up. He’d have sat there frozen for longer had then not interjected with “thank you Mr. President” the moment they detected a freeze.
What did him in was incoherent rambling.

Lol.
I think the “mic cutoff” feature was not intended for Trump, it was intended for Biden in case he became too incoherent
