Biden's team seems to have tried to scrub this video from the web almost entirely. It used to be easily available on YouTube, but it was replaced with a shortened version which cuts off the part where he just goes off the rails about Xi Jinping. I guess then they can just blame it on his "stutter".
Anyway, I found it on an old Facebook post from a year ago, so enjoy, and save it to your devices folks lest it be permanently memory holed.
Ok apparently it is still available on YouTube, it was only showing up with the shortened version when I looked earlier.
In any event, still an amazing gaffe.
Edit: PolitiFact: Joe Biden described America as “the foothills of the Himalayas with Xi Jinping.”FALSE Five Pinocchios ! 
Edit2: I replaced the stupid Zuckerberg URL with the regular YouTube one as pointed out by comrade @dead@hexbear.net because apparently I don't know how to use a search bar
Yeah I tried linking the direct .mp4 but it doesn't work without the spying code.
I enjoyed the video and saved it, for what it's worth!
Thanks for posting it!
