WASHINGTON (AP) — President Donald Trump’s impeachment now heads toward a historic Senate trial, perhaps as soon as next week. In a remarkable scene, senators will be serving not only as jurors but witnesses and victims of the deadly Capitol siege. The trial could begin as soon as Inauguration Day, when Democrat Joe Biden will take the oath of office. But the date has not been set and some Democrats suggest waiting. Trump faces a single charge of “incitement of insurrection.” In pursuing conviction, House impeachment managers will be making the case that Trump’s incendiary rhetoric before last week’s mob attack was not isolated. Rather, they will say, it was part of an escalating campaign to question the integrity of the U.S. election and overturn the results.
