We asked him to get to the bottom of why the Prime Minister of Canada has done interviews with so many American podcasts. Because we have a limited time slot we couldn't share that full interview with you in our broadcast edition. But we really liked what Aaron had to say, and thought you would too. So here is the full conversation.
