the course of this weekend and what we heard in the public hearings, help us understand how pivotal that testimony is likely to be on wednesday. >> i think of all the witnesses we'll see, gordon sondland is most anticipated because he's changed his testimony so far. he testified behind closed doors in a deposition. in the interim, the other witnesses that have come forward offering conflicting testimony that he has now had to adjust to. i now recall he says telling a ukrainian official they needed, in fact, to announce these investigations in order to unlock suspended security aid. all eyes i think will be on gordon sondland. there is that episode and the episode with the phone call in ki kiev. he puts us into the room with the president. every other republican so far, as republicans made clear, is offering their experiences and understanding through a distance. none of them had actually talked to president trump this week.
