Willie Brown is saying this now because he is an emissary of the Biden campaign to set the stage for Kamala Harris NOT being the choice for VP. It’s called easing her out of contention gently and in public to soften the blow when she is not the chosen one. She undoubtedly already knows this anyhow. It’s called prepping for her being set aside in public.
My close relative I now believe was right in saying that it will be Susan Rice, as Rice will be Obama’s watchdog, and his entree into controlling Biden’s every move. Biden is and will be Obama’s puppet. It is the price Obama has exacted from Biden for backing him in his run for President, that which Biden could not do without. Obama is Biden’s controller and Rice is his courier pigeon that has now landed on Biden’s political VP doorstep.
