Now with the historic impeach vote coming, battle lines being drown drawn. President trump railing against Democrats, calng it an impeachment hoax. A top Democrat accusing Mitch Mcconnell of complete subversion for coordinating with the white house over the trial. And now a freshman democratic congressman threatening to switch parties.
