OTTAWA - U.S. President Donald Trump remained resolute about using tariffs to fill America's coffers hours after starting a North American trade war that rattled markets and was described by ºÃÉ«tv Prime Minister Justin Trudeau as "very dumb."

"Tariffs are about making America rich again and about making America great again … there will be a little disturbance, but we're OK with that," Trump said during a marathon address to a joint session of Congress Tuesday evening.
