The House impeachment managers opened their prosecution of Donald J. Trump on Wednesday with a meticulous account of his campaign to overturn the election and goad supporters to join him, bringing its most violent spasms to life with never-before-seen security footage from the Jan. 6 Capitol riot.
Filling the Senate chamber with the profane screams of the attackers, images of police officers being brutalized, and near-miss moments in which Vice President Mike Pence and lawmakers came steps away from confronting a mob hunting them down, the prosecutors made an emotional case that Mr. Trump’s election lies had directly endangered the heart of American democracy.
