President Trump on Thursday officially ordered a 25 percent tariff on imported steel and a 10 percent tariff on imported aluminum, putting him at odds with traditional Republican economic priorities. The tariffs will take effect in 15 days, with carve-outs for Canada and Mexico under the condition that the North American Free Trade Agreement can be renegotiated. "You don't wanna pay tax? Bring your plant to the U.S.A.," Trump said during his announcement. Trump added that he is open to exempting certain countries "as long as we can make sure their products no longer threaten our security," referring to the national security provision that has allowed him to impose the new taxes.
