The more I hear of Comey's testimony and analysis of it the worse things look for Trump.
So many of the most important questions in the matter Comey stated that it could not be answered in an open session.
-Was Flynn part of the Russia investigation? Closed session
-Why did the AG recuse himself? Closed session
-Did Trump's administration create a back channel with Russia? Closed session
-Was Trump personally under investigation? Closed session.
-Do you believe Trump colluded with Russia? Closed session.
That is a lot of red flags for me. If the answer were simply no, that Trump was not under investigation, then why not just say so? Maybe, just maybe there are perfectly reasonable answers to all of these that just can't be made public but I don't know how probable that is.
Now some will say that Comey told Trump multiple times that he was not under investigation but I consider that relatively meaningless given Comey's job and the nature of such an investigation. Law enforcement officers are allowed to lie to people for starters and in an investigation such as this is would make perfect sense that you would need to keep the investigation secret. If you are investigating someone, especially someone with the country at their fingertips, you do not want to let them know they are under investigation.
The public testimony certainly did not clear Trump, it just left us knowing that most of the biggest questions were not answered publicly. I think Trump's request to drop the investigation is both incredibly unethical and borderline illegal. Depending on what the answers were in the closed session, I think it may be conceivable that there is enough to impeach the president. Heck, we impeached Clinton over a lie about a sex scandal, why not Trump for something much more serious?
Now I do say this all with the reservation that the answers in the closed setting could change my position. Like I said, if the whole picture is viewed it might all make perfect sense but I doubt that is the case and right now the testimony makes me suspect Trump more, not less. When it comest to the question of whether Trump obstructed justice, I get that it comes down to he said/she said but it would seem that incident is just the tip of the ice berg. Heck, in a lot of criminal investigations it comes down to the cops word vs the accused word but generally the cop's word is accepted as true over the accused given the nature of the whole thing.
