US Senator Lindsey Graham (R-SC) makes no bones about his position on the likely upcoming impeachment trial of US president Donald Trump. "I am trying to give a pretty clear signal I have made up my mind," he tells CNN International's Becky Anderson. "I'm not trying to pretend to be a fair juror here." Well, okay, then. Graham has publicly disqualified himself as, and should be excused from serving as, a juror.
