behind closed doors? >> there's so many and i think he's going to spend a long time in there. first of all the documents are really important. giuliani held up his phone, he read some text message dollars ba messages with volker. i want to to go through everything about his communications with the ukrainians related to biden or the company. there's another piece of that this that i'm curious about. there's a part that says the ukrainians had knowledge that the money was being withheld and so that's something i would want to know from volker, how did the ukrainians know that? and also that they were told in sort of a pregame of the president's conversation with zelensky that the president wanted to talk about biden and this investigation into biden. so i am very curious to know who made that call to the ukrainians? was it the white house? was it state? what knowledge does volker have of know of those actions?
