Tonight on The ReidOut, Joy Reid invites you to revisit Justin Trudeau’s infamous 2019 hot mic moment mocking Donald Trump, the same year as a notable display of affection with Melania Trump. Fast forward to today, and Trump is joking about annexing Canada and demoting Trudeau to governor after the Canadian Prime Minister's failed appeasement trip to Mar-a-Lago. Meanwhile, the case of a wealthy, young valedictorian accused of murdering a healthcare CEO has sparked debate among conservatives over when killing is condemned and when it is excused. Plus, Senator Elizabeth Warren joins Joy to discuss Trump’s attacks on regulations and consumer protections, as well as Dr. Oz’s controversial proposals targeting Medicare.
