Donald Trump's historic impeachment second trial, on a charge of inciting last month's deadly storming of the U.S. Capitol, began on Tuesday, making the Republican the first former U.S. president to be tried in the Senate.
"The Senate will convene as a court of impeachment," said Democratic Senator Patrick Leahy, who is presiding, at the outset of the proceedings.
Trump was impeached by the Democratic-led House of Representatives last month for his role in the Jan. 6 attack on the Capitol by a mob of his supporters. He made a fiery speech to a crowd of supporters in Washington that day, repeating false claims that his Nov. 3 presidential election defeat was the result of widespread voting fraud and encouraged supporters "to fight like hell."
