this revelation, how could this revelation impact the impeachment inquiry, or this tick tock leading up to this phone call with the ukrainian president? >> it fleshes out some of the grounds for the impeachment inquiry. but any evidence that there was, as you say, pressure on the ukraine, i did it again, ukraine, long before the phone call of july, tens to show or could show that there was no quid pro quo, there was no this for that in the phone call. no demand, no pressure. but owner, it really doesn't matter under federal law how separate the quid pro quo is, it could be months earlier and a benefit not necessarily received by each of the parties but somebody important to them so traditional notions of quid pro quo have been so expanded by federal criminal law, that just because the pressure may have come at a different time, or the parties were not direct recipients, doesn't rule out the notion i guess of quid pro quo.
