Good evening. I'm Jeff Bennett. And I'm Omna Nawaz. On the news hour tonight, businesses are hit by new tariffs that the United States is slapping on Mexico and Canada in what's become a global trade war.

Canadians are reasonable and we are polite, but we will not back down from a fight.

Ukraine scrambles to salvage its fractured alliance with the U.S. after the White House suspends military aid to the country at war.

And President Trump prepares to give his first address to Congress since returning to office as he slashes the federal workforce

Speaking directly to President Trump, Canadian Prime Minister Justin Trudeau announced

It may well be short-term price movements, but in the long term, it's going to be completely

different.

Commerce Secretary Howard Lutnik defended the tariffs on CNBC and said they could be lifted later on.
