President Trump announced a new 25% blanket tariff on all steel and aluminum imports. This tariff is part of a growing list of tariffs his administration has already threatened or imposed.

President Trump announced he is imposing tariffs on foreign steel and aluminum to a flat rate of 25 percent, stating that the change will happen "without exceptions or exemptions."

The president, who has threatened and delayed other tariffs, said he will announce the new measures Monday. Canada and Mexico are among the U.S.’s top steel suppliers.
