The GOP is flailing around significantly.
Trying to come up with exculpatory explanations for Trump's Ukraine policy/mess.
And trying to muddy the waters and discredit the House investigation however possible.
The process questions on their face are absurd. Graham wants the House process to be exactly like it was for Clinton and Nixon, only both those cases had independent special counsels to do fact finding and Graham knows exactly why there won't be one on Ukraine, and it has nothing to do with Democrats in the House.
And now Graham is making an equally absurd argument to discredit Ambassador Taylor's testimony, calling it "hearsay." The guy is the Ambassador of the United States to Ukraine. He's not a fucking waiter who overheard two people talking over lunch. If he was under the impression that this was a Quid Pro Quo the
only way that can be is if there was. And you can be damn sure that if Taylor had that impression, the Ukrainian's did too.
Unless Taylor is just straight up lying, but unfortunately for the GOPers trying to defend Trump, and eventually Trump himself, there are contemporaneous texts and (reportedly) copious notes that Taylor can or already has provided.
