I know this might be inappropriate to say, but if I’d been standing next to Biden when he said that, I would've wanted to choke him out. "DO YOU HAVE ANY IDEA WHAT IS AT RISK!?! DO YOU EVEN REMEMBER HILLARY!?!?!" Go sit yo punk ass down!!".
You do realize that he does not care? He is pissed off at Kamala for throwing him out of running for the second term
I doubt that. I think he saw he was falling behind in the polls and wasn’t making any significant progress. Plus, with the DNC and public opinion pushing for him to step down due to poor performance, it was what it was. I highly doubt he did this intentionally; he was just trying to help but handled it poorly.
