re: Can Republicans argue so what Ukraine was pressured,

I guess we're all just a little guilty of seeing what we want to see in these things, and of course we have carte blanche to interpret as we see fit. So in that vein, my response to the FBI question is this: I see the mentions of AG as equivalent to mentions of the Justice Department/FBI. As far as Trump "repeatedly asking Zelensky to investigate," I'm convinced Trump's overall point was to merely bring the issue to the forefront, then we'll have AG get with you on details as to who could do what in a cooperative endeavor.
