Although many Senate Republicans have signaled their intentions to acquit former President Trump of impeachment charges, Democratic Senator Chris Murphy thinks the trial should proceed anyway. "Ultimately we have a constitutional responsibility in the Senate to process these articles…you can't skip the accountability phase for a President who tried in the final days of his presidency to lead either a non-violent or a violent insurrection against democracy." If the situation was reversed, Murphy adds, and it was a president from his own party being impeached, he would still want to hold that president accountable. Sadly, he concludes, the same cannot be said about many of his colleagues across the aisle.

Murphy's conversation with Ian Bremmer is part of the latest episode of GZERO World, in which Bremmer is also joined by freshman Republican Congresswoman Nancy Mace. The episode will start airing on public television nationwide beginning this Friday, January 29th. Check local listings.
