It was the last thing they could hang on Trump before he left office, and just like everything else they tried to hang on Trump, the truth has emerged and is vindicating Trump. From James Bovard at mises.org:
The Senate impeachment trial of former president Donald Trump confirms historian Henry Adams’s adage a century ago that politics “has always been the systematic organization of hatreds.” The impeachment process was a farce that should fortify Americans’ disdain for Washington. Considering how Democrats are using the January 6 clash at the Capitol to justify enacting a new domestic terrorism law, Americans need to recognize the frauds that permeated this process from the start.
At last week’s trial, House impeachment manager Jaime Raskin (D-MD) boasted to the Senate, “I think we have done an exceedingly thorough and comprehensive job with all the evidence that was available.” But the House Democrats did not bother accumulating evidence before the trial. Instead, House impeachment managers showed up at the Senate with video clips and tweets and a bunch of overheated rhetoric and thought that should suffice. House impeachment manager Ted Lieu summarized the proceedings: “Trump is receiving any and all process that he is due.”
Shortly before the Senate was expected to cast the final vote on the trial, Raskin announced that the House team wanted to call an actual witness. Democratic senators first voted to call witnesses and then, a couple of hours later, Senate Majority Leader Charles Schumer (D-NY) announced that, instead of witnesses, they would simply add one news article based on hearsay to the official record. Unfortunately, the only laughter that erupted on the Senate floor occurred when Trump’s lawyer threatened to summon witnesses for depositions to his law office in “Philly-delphia.” (His house was vandalized after the trial ended.)
