In a final crescendo late Friday, Schiff recited the two articles of impeachment against Trump, declaring intermittently that each allegation “has been proved.” He also offered an extended appeal to "moral courage" — one aimed implicitly but squarely at the handful of Republican senators who say they're open-minded — by suggesting that true courage "comes not from disagreeing with your opponents but from disagreeing with your friends."

Schiff also used his final speech to run through a litany of anticipated defenses by Trump's lawyers, who begin their own defense on Saturday, and attempted to knock down each one. He told senators to ignore arguments that the House's impeachment was partisan or that it was procedurally defective, contending that such excuses were an attempt to distract from Trump's own conduct.

Moments before the clock struck 9 p.m., Schiff ceded the floor, concluding a three-day argument after delivering his most visceral remarks yet — a warning that Senate Republicans, too, could someday be targeted by Trump.

“I'll tell you something, the next time it just may be you. It just may be you,” Schiff warned. “Do you think for a moment that any of you, no matter what your relationship with this president, no matter how close you are to this president, do you think for a moment that if he felt it was in his interest, he wouldn't ask you to be investigated? And if somewhere deep down below you realize that he would you cannot leave a man like that in office when he has violated the constitution.”

On their final day of arguments, Democrats continued to toggle between exhaustive recitations of the evidence and appeals to senators’ consciences — saving their loftiest and most potent arguments for the primetime audience. They’re also making one last plea for Senate Republicans to call witnesses in the trial, most prominently acting White House chief of staff Mick Mulvaney and former national security adviser John Bolton. Other witnesses have described both as central players with firsthand knowledge of the events at the heart of the Ukraine scandal.

Democrats focused the remainder of their arguments on the charge that Trump obstructed Congress’ investigation of the Ukraine matter. He directed about a dozen high-level witnesses not to cooperate with the House’s probe, including Mulvaney, Bolton and senior officials in the White House budget office. Many of the 17 witnesses who testified before House investigators — including several senior White House and State Department officials — defied Trump’s orders.

Those witnesses provided the backbone of the allegations that Trump pressed Ukraine’s newly elected president, Volodymyr Zelensky, to investigate former Vice President Joe Biden, as well as a debunked conspiracy theory, promoted by Russia, that Ukraine — not Russia — hacked a Democratic Party server in 2016. Those witnesses provided evidence that Trump withheld $391 million in military aid to Ukraine and a White House visit for Zelensky amid Ukraine’s active war against Russian aggression, as part of the alleged pressure campaign.
