One interesting thing to watch in the impeachment proceedings:
Will Hurd is a smart, principled former CIA officer on the House Intel Committee - who is not seeking re-election. You can seek his reasons for yourself, but one of the reasons he gives is, by his words, "I want to make sure there's 15, 20 folks like me that are in Washington, DC. ... I left the CIA in order to help my country in a different way. In addition to collecting intelligence I had to brief members of Congress and I was pretty shocked by the caliber of our elected officials."
With that being said, he is proceeding with his questioning in the impeachment hearings in an entirely different manner than the rest of the Republican participants. For instance, in the Yovanovich hearings he was intent on figuring out what Giuliani's motivations were, presumably because they were either not at all or not entirely directed toward the purposes of the impeachment hearings. Now, he did not have enough time to complete this line of inquiry - but it's also a legitimate line of inquiry (which may or may not exonerate the President) - but none of the rest of the Committee has much interest in a legitimate line of inquiry. That line of inquiry may also be beyond the capability of the House Intel Committee without the participation of a large part of the intelligence community, and that investigation is probably being performed currently with Giuliani under criminal investigation, but it is at least an example of a Republican using the hearings to actually extract new information from the witness that pertains to the subject. I will be checking in to Hurd's questioning in each of the hearings just to see what they SHOULD look like on the Republican side. I will not be paying attention to the deliberate stunts like the one pulled today where the Republicans tried to have a committee member speak who was not authorized to speak - a rule that applies equally to the Democratic members - just for it to be put up as red meat on FOX News' website without any context added.
IF the President were innocent, the Republicans would need several Will Hurds on the committee to protect the American people from falsely impeaching a President due to incompetence on the part of the Committee members. Unfortunately, we do not currently have that protection. Luckily, the idea that Trump didn't have corrupt intent - or, at the very least, "proceeded with such negligent due diligence as to be impossible interpreted as anything other than corrupt" - doesn't pass the laugh test.
(As has been touched on multiple times in the hearings, it is essential that investigations into corruption be conducted in a holistic manner and not selectively to avoid the appearance of preferential treatment, and it is essential that investigations into political opponents be handled entirely independently of those who stand to personally benefit in order to avoid the appearance of impropriety, and Trump violated both of these principles in his request, along with many, many other principles which are essential to avoid the appearance of impropriety. Oh, and much, much more...)
