Tears on the Senate floor. Shocking footage of the insurrection. A bumbling and widely panned performance by Donald Trump’s legal team. The former president’s second impeachment has now moved to trial, and House Democrats came prepared. A little over one month after a riotous mob laid siege to the very chamber in which the trial was now taking place, Democrats presented such a damning trail of evidence that that it caused one GOP senator, Bill Cassidy, to change his vote on the trial’s constitutionality.

Mother Jones national political reporter Pema Levy joins Jamilah King from DC to recap and explain what went down on Day One. Pema explains how the House impeachment managers, led by Rep. Jamie Raskin, a constitutional scholar, will set out to prove Trump responsible for the deadly attack. Meanwhile, Republican Senators are expected to try to wiggle out of the toxic political shadow of their former president by sticking to an argument that the proceedings are unconstitutional, letting Trump get off scot-free. Trump’s acquittal is all but a foregone conclusion, and the trial is expected to be an unusually swift one. But as Pema explains, what happens over the next week or so will still be incredibly consequential and perhaps even more damaging for Republicans than Trump’s first impeachment.
