Political strategists Melanie Paradis, Susan Smith, and Kim Wright debate this week's developments on foreign election interference. Polling analyst Eric Grenier (The Writ) joins Michael Serapio to analyze what Canadians think of the interference issue. And Jean-Pierre Kingsley, Canada's chief electoral officer from 1990 to 2007, offers his view on the allegations -- and on David Johnston's appointment as independent special rapporteur.
