Mitch McConnell, in explaining why he voted to acquit Drumpf, specifies that the House managers made their case and that Drumpf was responsible for the crimes on January 6th.
This is not an exaggeration or a mischaracterization of what he said. 
""There's no question, none, that President Trump is practically and morally responsible for provoking the events of the day," he said on the Senate floor. "The people who stormed this building believed they were acting on the wishes and instructions of their president. And having that belief was a foreseeable consequence of the growing crescendo of false statements, conspiracy theories, and reckless hyperbole which the defeated president kept shouting into the largest megaphone on planet Earth.""
He explains that his vote to acquit is because he doesn't believe the Senate has the power to convict him. His logic is strained when it's not flat-out mischaracterization.
He claims that the standard by which the Impeachment was brought would result in the Senate being able to impeach any citizen. This is an absurd reading of the Constitution. It's not ambiguous as he claims here. Anybody who has held public office can be impeached for their conduct in office.
But honestly, it makes sense that he would interpret the Constitution this way. It favors the corrupt politician. By punting on the Senate's responsibility to Impeach public servants he's taking away one more way in which he and his cronies could potentially be punished.
""President Trump is still liable for everything he did while in office," he said. "He didn't get away with anything yet. We have a criminal justice system in this country. We have civil litigation.'""
Based on our history with McConnell it's worth looking for the lie and manipulation in this sentence. In this case, the Federal criminal justice system is generally headed by the DOJ. Although the DOJ tries to appear independent it as an arm of the executive. In that vein the Executive and Legislative branches are responsible for this.
This is a style of lie McConnell uses a lot, and pulled in this speech when he repeats the lie that the House chose not to deliver the Impeachment articles while Drumpf was still in office. He flashes the left hand while the right hand has already signed the paperwork saying it won't happen. Biden says he doesn't want to prosecute and you can bet your ass that McConnell's not going to pressure the DOJ into prosecuting Drumpf for this.
We come here in search of a place to express our thoughts outside of the direct control and surveillance of unaccountable, mega-corporations. There is no common theme that binds us other than these being the bonds we've chosen rather than those that have been chosen for us.
