The latest video from Trump was a rather poor deepfake. The tweets after his 12 hour ban are not characteristic of him.

Video:

• His hair glitches vertically in the first 4 seconds of the video
• His neck line is a glitchy mess throughout the video
• His hands are never fully visible
• Video quality is not good
• He uses strange phrases such as "seat of democracy", he doesn't say he won, he doesn't even mention the 14 yr airforce vet that died

Tweets:

• Why would he be tweeting about the inauguration, which is 12 days from now? Trump never makes absolute statements, he keeps his options open. He wouldn't be thinking 12 days from now, he's be thinking about what moves he's going to be making 24 hrs from now. And the only thing he's saying is that he will NOT appear in public.
• His tweet before that is comically stupid, and is clearly not him.

Something has happened to Trump, whether he's being held or has been physically harmed, I don't know.
