Former US President Donald Trump's impeachment directors from the House of Representatives made clear that the evidence against him is overwhelming and that there is no defense of his actions.
In a testimony, Democratic-led impeachment managers said Trump's incitement to revolt is "the most serious constitutional crime a president has ever committed."
Trump was accused of encouraging his supporters to go out on a march towards the Capitol on January 6, which turned into a storming of the building in which 5 people were killed.
For his part, a source said that Trump's second trial for inciting the bloody attack on the Congress building will begin Tuesday with a discussion about whether the procedures are unconstitutional because he is no longer president.
The source familiar with the discussions said Trump's trial for incitement to revolt would then include deliberations lasting up to 32 hours, starting at noon on Wednesday.
The nine Democratic lawmakers in the House of Representatives who will play the prosecution role hope to persuade the 100-member Senate to convict Trump and ultimately prevent him from holding public office again.
Two questions
Trump, the Republican, ended his 4-year term on January 20, after losing the November 3 presidential election to Democrat Joe Biden.
Trump supporters tried to drop the case against him, saying that holding a trial after the president left office was an unconstitutional move, but they failed to do so.
House invitees rejected this argument in their memo to the Senate last week, and presented their case to condemn Trump in order to protect American democracy and national security and to deter any future president who might consider inciting violence in pursuit of power.
To convict Trump, Democrats must persuade 17 Republicans to join them in the Senate in the vote.
Trump is the first US president to be held accountable twice, and the first president to face trial after leaving office.
