God bless the internet and video immured roughly forever now.  Watch as Mr Obama stammers uncontrollably.  What truly happened?

Mr Obama is so overtaken by an adrenaline dump because of his hatred for Trump that he momentarily loses the ability to speak.  On the other hand, no one ever accused Obama of being the world’s finest extemporaneous orator.

My guess?

The TelePrompter broke.
