President Trump’s top economic adviser said Wednesday that despite imposing new tariffs against close allies, Trump will champion free trade during a weekend trip to Canada for a summit of the G-7 group of wealthy industrialized countries.

“I regard this as much like a family quarrel. I’m always the optimist,” Kudlow told reporters at a briefing that previewed the trip, during which Trump will have meetings with Canadian Prime Minister Justin Trudeau and French President Emmanuel Macron.
