counselor to president obama where he oversaw climate policy in the white house. thanks for coming on. you did serve under obama. let me ask, why couldn't he ever get a deal like this on a huge issue like this? is today's win a product of joe biden being an ex-senator who gets along with republicans? is it as some might argue because he isn't a black man accused of being born in kenya? >> look, i think there's a lot in that question. it's good to be back on with you. thanks for the country. i think that what biden had was both a decade of lack of progress on infrastructure behind him and a dedication to try to find bipartisan solution. often during the obama administration, when you needed to make a final deal, it was joe biden that went up to the hill to negotiate with mitch mcconnell or the republican leadership in the house to see if they could find common ground.
