worked and giuliani was running point on it with the president. giuliani was saying this yesterday, i've been thinking about what this means all day. i want to get both your feed book. the investigation i conducted concerning 2016 ukrainian collusion and corruption was done solely as a defense attorney to defend my client against false chajs that kept changing one after another. what does that mean and what does that mean in a legal or constitutional sense as we enter impeachment? >> talk about changing explanations, it's giuliani's before he was rooting out corruption in favor of him. what he's trying to do there is make a play for privilege, but i think it won't work. and boy is he tailor made to be the villain here. the fact he's there makes it so clear that of course he's acting for trump's personal interest and not for any broader anti-corruption in ukraine. so he's front and center.
