Last year I had a similar experience searching for CNN's interview with Biden and Harris. In that case, I cound only find CNN Brasil's release of the full interview (with Portuguese spoken over it). Some of what he says is embarrassing, but those parts are difficult to find on YouTube.
Yes, it’s worth noting that this town hall was also a CNN affair, and the only full video I was able to find was not posted by them. It’s on some other random channel. Someone at CNN and/or YouTube decided this was bury worthy.
