[Ed. – Don’t surprised if more Dems jump ship.]
Whenever an impeachment trial takes place, it’s the House’s job to gather evidence, obtain documents and hear witnesses before presenting the case to the Senate. The Senate’s job is to hear the case and be impartial. They’re essentially the jurors and decide whether or not the president is removed from office.
Although the Senate is supposed to be impartial and open, the votes thus far have come down on party lines. Sen. Joe Manchin (D-WV), a Blue Dog Democrat, is actually following the impartiality factor.
Before Saturday’s opening statements from the president’s defense team, Manchin said he took his “oath to the Constitution to protect and defend and [his] oath of impartiality.”
After Saturday’s hearing, Manchin gave President Trump’s team kudos for making him think about the House’s case and their lack of witnesses.
