Make sure you watch the whole thing. That MSNBC anchor, whomever she is (nope, I didn't look it up), was in PHYSICAL PAIN during that clip. She wanted more than anything to not have to jump in and betray her blatant bias by finishing Biden's sentence for him as though he were a small child. But eventually she had no choice. She dove in there and saved him.
