More speech highlights:

1. The seriousness of Trump's offenses:
--“And really, corrupting an election process in a democratic republic is about as abusive and egregious an act against the Constitution—and one’s oath—that I can imagine. It’s what autocrats do.”

2. Dismissing the "no actual crime!" defense:
--“The historic meaning of the words 'high crimes and misdemeanors,' the writings of the founders and my own reasoned judgment convince me that a president can indeed commit acts against the public trust that are so egregious that while they’re not statutory crimes, they would demand removal from office. To maintain that the lack of a codified and comprehensive list of all of the outrageous acts that a president might conceivably commit renders Congress powerless to remove such a president defies reason."

3. Dismissing the unfounded allegations against both Bidens:
--"Given that in neither the case of the father nor the son was any evidence presented by the president’s counsel that a crime had been committed, the president’s insistence that they be investigated by the Ukrainians is hard to explain other than as a political pursuit."

Even more speech highlights:

4. On the need for more evidence at trial:
--"I sought to hear testimony from John Bolton, not only because I believed he could add context to the charges, but also because I hoped that what he might say could raise reasonable doubt and thus remove from me the awful obligation to vote for impeachment."

5. Acknowledging the political repercussions to himself:
--"I am aware that there are people in my party and in my state who will strenuously disapprove of my decision, and in some quarters, I will be vehemently denounced. I’m sure to hear abuse from the president and his supporters. Does anyone seriously believe that I would consent to these consequences other than from an inescapable conviction that my oath before God demanded it of me?”

6. Taking the long view:
--"Were I to ignore the evidence that has been presented and disregard what I believe my oath and the Constitution demands of me for the sake of a partisan end, it would, I fear, expose my character to history’s rebuke and the censure of my own conscience."
--"I will only be one name among many, no more, no less, to future generations of Americans who look at the record of this trial. They will note merely that I was among the senators who determined that what the president did was wrong, grievously wrong.We are all footnotes at best in the annals of history, but in the most powerful nation on Earth, the nation conceived in liberty and justice, that distinction is enough for any citizen.”
