Senate Minority Leader Charles Schumer told reporters on Tuesday that he would be an impartial juror in the forthcoming impeachment trial of President Donald Trump, claiming that he had not yet made up his mind and wanted to hear from additional witnesses -- who did not appear in the House -- before he made a formal decision. He and fellow Democrats have accused Republicans of prejudging the outcome, even though most Senate Democrats -- including several presidential candidates -- have already said that Trump should be removed from office.
