Highlights of the opening arguments in President Donald Trump's impeachment trial and what's ahead.
'CORRUPT SCHEME'
* Adam Schiff, the lead Democrat prosecutor, spoke for more than two hours, laying out the case House Democrats made in weeks of hearings last year.
* Schiff, chairman of the House Intelligence Committee, said Trump had pursued a "corrupt scheme" to abuse his presidential power and then obstruct Congress' investigation.
* He appealed to senators not to be "cynical" about the politics of impeachment, asking them to draw on the intent of the nation's Founding Fathers.
* The founders "feared that a president could subvert our democracy by abusing the awesome power of his office for his own personal or political gain," Schiff said. "And so they devised a remedy as powerful as the evil it was meant to combat: Impeachment."
FIDGETY SENATORS
* The challenge before Schiff and other House managers was clear, as they tried to win over not just fidgety senators sitting silently in the chamber but a divided American public. Senators were especially restless on Wednesday, as lawmakers convened less than 12 hours after a marathon session that stretched to nearly 2am.
* Jason Crow, a Democrat from Colorado and House impeachment manager, had trouble holding the attention of senators, who by Senate rules were sitting in silence without access to phones or other electronics. Many senators left their seats and headed to nearby cloak rooms, or stood in the back or openly yawned as Crow talked about Trump's hold on military aid to Ukraine. At one point, more than 10 senators' seats were empty.
* Crow, a military veteran who tried to emphasise the importance of the delayed aid to Ukraine, noticed the unusual level of activity, telling Chief Justice John Roberts at about 5pm that he saw a lot of senators moving about. He wondered aloud if the Senate wanted to take a recess. No such luck. Roberts urged him to continue, and McConnell announced the Senate would not break until 6:30pm.
A TRUMP TWEETSTORM
* As Democrats presented their case, Trump blasted the proceedings from afar, joking that he would face off with Democrats by coming to "sit right in the front row and stare at their corrupt faces."
* Trump, who returned Wednesday from a global leaders conference in Davos, Switzerland, set a presidential record for activity on his favourite social media platform, sending at least 124 tweets in a single day, according to Factbase, a service that compiles and analyses data on Trump's presidency.
DEMONSTRATOR REMOVED
* Just before dinner, Capitol police swiftly grabbed and dragged out of the chamber a man in the visitors' gallery who was yelling. As he was being held in a hallway outside the chamber, the grey-haired man could be heard shouting, "Dismiss the charges!"
WHAT'S AHEAD
* Democrats will continue arguments continue through Friday under rules approved by the Senate. Trump's lawyers will then have up to three days to rebut the Democrats' case.
* While polling suggests widespread agreement that Trump should allow top aides and former aides to appear as witnesses at the trial, that possibility seems remote.
* In wrangling over rules for the trial that stretched into the early morning hours, Republicans shot down, one by one, Democratic efforts to get Trump aides to testify, including former national security adviser John Bolton, Secretary of State Mike Pompeo, and acting chief of staff Mick Mulvaney.
* While some Republicans have expressed openness to new witnesses, it is unclear if four GOP senators will join Democrats to allow new testimony.
