Never-seen-before security video of Capitol riot to open Trump ...

"It will show that Donald Trump surrendered his role as commander in chief and became the inciter in chief," effectively committing, "the greatest betrayal of the presidential oath in the history of the United States."Next, Rep. Joe Neguse, D-Colo., another manager, said that chronology proved that Trump's statements were a "call to arms" and "not rhetorical" statements.The managers have 16 hours over two days to make their presentations and then Trump's attorneys begin their defense with the same amount of time allotted — proceedings that will take the trial into the weekend and likely beyond.House managers, however, aren't likely to use the full 16 hours, the senior aides on the impeachment manager team said.When opening arguments are done, senators will be able to question the two sides for a total of four hours by submitting written questions to Sen. Patrick Leahy, D-Vt., the Senate president pro tempore, who is presiding over trial and who will read them aloud.Wednesday's proceedings follow a riveting first day of the trial that started with a chilling 13-minute video montage of the devastating events of the riot at the U.S. Capitol on Jan. 6 and ended with a vote declaring that trying a former president is constitutional and allowing it to continue.That 56-44 vote capped debate that took up much of the first day of arguments from the House impeachment managers and Trump's legal team.
