Five Republicans join vote for witnesses in Trump Senate trial –video

Five Senate Republicans voted with the Democrats on Saturday, that the Senate should call witnesses in the impeachment trial of Donald Trump.

Before the 55-45 vote, Trump's impeachment lawyer Michael van der Veen warned senators that if Democrats wished to call a witness, he would ask for at least 100 witnesses and insist they give depositions in person in his office in Philadelphia - a threat that prompted laughter from the chamber.
