President Trump announced Thursday that next week he will formally impose a tariff of 25 percent on steel imports and 10 percent on aluminum imports — news that sent the Dow Jones Industrial Average tumbling more than 500 points, or more than 2 percent.
Treasury Department officials had been concerned about the market reaction during debates Wednesday night over announcing the tariffs, although by late Thursday morning it appeared critics of the plan had temporarily stalled such a public declaration, Politico reports. Trump then made the announcement during a listening session, and tweeted: "We must not let our country, companies, and workers be taken advantage of any longer. We want free, fair, and SMART TRADE!"
