the last few months, affected the way he's going to approach this? >> i think he is going to approach this as unpersonally as possible. i think it's the president who wants to make this look like it's a person score that's being settled, that this is all given driven by partisan politics and i think it's incumbent on nadler if he wants to have any hope of persuading more americans that impeachment is legitimate to keep the personality stuff out of this. but donald trump is going to continue to talk about how nadler has been at him for years, and he's going to continue to portray this whole thing as a sham no matter what happens. so regardless of the actual roles and opportunities republicans have to participate, donald trump believes that anything run by the house democrats is a sham. they're bought into that argument and not going to legitimize the house proceedings by participating. the president has tweeted he's waiting -- this will be on our turf soon meaning the senate.
