How did they manufacture the audio? Deep fakes are easy to make, but audio like that (multi minute speech) identical to Trump's voice isn't.
The truth is, Trump cucked out because every "legal option" was blocked and he doesn't have the mindset to kick off a revolution to preserve freedom and the Republic.
I'm sure they could do it if they poured many resources and a long time to perfect it, but not on the fly like that
The simple reality though, is Trump was not abducted. His family would be screaming about it right now. The reality is, he gave up.
