Canadian Prime Minister Justin Trudeau broke down in tears Sunday during his farewell speech during a Liberal Party conference.

Both Trudeau and his replacement as Liberal leader, Mark Carney, blasted U.S. President Donald Trump in their speeches and vowed to fight back against Trump’s tariff threats.

Trudeau announced he would resign in January amid cratering poll numbers, dire election forecasts for the Liberal Party, a growing sense among both Liberals and the general electorate that he could not go toe-to-toe with Donald Trump, and a severe crisis within his party.
