With rules set, the Senate hears opening arguments

The rules are set and the opening arguments began today in the impeachment trial of US President Donal Trump in the Senate. Also, did the Crown Prince of Saudi Arabia, Mohammed Bin Salman, hack into Amazon chief Jeff Bezos's smartphone? Two UN officials say that's exactly what happened. Saudi Arabia calls the allegation against its crown prince, "absurd." And, as world leaders prepare for a commemoration in Israel on Thursday to mark the 75th anniversary of the liberation of the Auschwitz concentration camp, the president of Poland is refusing to participate.
