Donald Trump’s second impeachment trial started on Tuesday with extensive video footage of the deadly January 6 siege on the US Capitol, as Democrats made the case that the former president should be convicted for inciting an insurrection.

Following four hours of debate over whether it is constitutional to put a former president on trial in the Senate, lawmakers voted to let the trial proceed.

Jamie Raskin, the Democratic congressman from Maryland who is the lead impeachment manager and de facto chief prosecutor, began the hearing with the often graphic 10-minute video. The compilation of clips of the attack, as seen from outside and inside the Capitol, included a snippet of Trump encouraging the crowds to “fight like hell” and march on the legislature. Raskin wrapped up the prosecution’s arguments on Tuesday with an emotional speech, in which he reminded lawmakers that he buried his 25-year-old son, who died at the end of last year by suicide, just one day before the Capitol siege. Raskin also had his daughter and son-in-law with him at the Capitol on the day it was attacked, as the family grieved together.

Following the Maryland lawmaker’s remarks, Bruce Castor, Donald Trump’s lawyer, denied Donald Trump was responsible for the riot in a meandering opening statement in which he heaped praise on senators and shared a variety of philosophical musings. (FT, NYT, Bloomberg, Politico)
