What is President Donald Trump's approval rating today in the U.S.? Here's what polls say Americans think of Trump's job performance and recent tariffs.

President Donald Trump has sent letters this week outlining higher tariffs countries will face if they don’t make trade deals with the U.S. by Aug. 1.

Trump wrote to Carney to inform him that, from August 1, Canada will face a 35 percent import tariff after the two sides failed to reach a deal during the recent pause. The American leader said he would consider revising the 35 percent tariff "if Canada works with me to stop the flow of Fentanyl".
