Today, the fourth day of the Impeachment, the house managers wrap up their case. They close their arguments on Trump’s first article of impeachment, and then turn to the second--obstruction of Congress. Today is their last chance to speak before the President’s counsel presents their case. The managers have left everything they have on the gallery floor. For the past three days, they have spoken for eight hours or more, trying to convince the senators before them that Trump should be removed from office.
