I believe that the word salad version was in the promo and the more concise version was in the aired interview.
It looks like they put a longer version in the promo that made her look bad - with the goal of enticing Pubs to watch? - and then edited and showed a much more concise version in the televised interview.
It's a really, really stupid thing for CBS to do.
But if CBS were really trying to be in the tank for Kamala, they'd have used the edited version in both places. Instead, they've created a controversy where otherwise there was merely an inartful answer.
