Tom, Bill Taylor had first-hand knowledge via conversations with White House aides, national security officials and Trump’s point people in Ukraine that there was a concerted effort to force Ukraine into a quid pro quo. Over the course of several months, he talked to high-level officials at the National Security Council, officials in Ukraine’s presidential office and two of the “three amigos” designated by Trump to handle Ukraine policy outside the normal diplomatic channels. “I was in the regular channel” of diplomacy, Taylor testified, “but I was also in the irregular one.” He also testified that his aid had first-hand knowledge of what Trump said and we also learned that she will be testifying under oath to that first-hand knowledge.
Schiff did not lie, but I will entertain your point given you are doing better than Don Diego and you actually made a substantive argument in part of your post. Even if he did, it isn't relevant to what Trump did. It is a ludicrous argument to make. Devin Nunes and Gym Jordan's pants were on fire today. Is their telling of lies evidence that Donald Trump did the things that he is accused of? In court, a judge would say what Gym Jordan, Devin Nunes and Adam Shiff said are irrelevant to the proceeding as they have no probative value. Such claims would be inadmissible. If you want to start a thread about Adam Shiff lying, and then provide evidence to make your point do so, but it is unrelated to Trump's guilt or innocence.
Don Diego, see my answer to Tom's questions.
Oh, I almost forgot. If you want more first-hand evidence of what happened or what Trump said or did, tell Trump to quit obstructing justice and allow those with first-hand knowledge to testify. Hell, Trump can testify himself. I hope when the charges are prepared to send to the Senate a count of Obstruction of Justice is added for every witness that was subpoenaed but didn't appear because Trump instructed them to break the law.
