U.S. President Donald Trump said on Saturday he did not warn car industry executives against raising prices as tariffs on foreign-made autos come into force, telling NBC News he "couldn't care less" if they do. The White House has been preparing to impose new tariffs on a range of consumer goods on April 2, a move that has drawn criticism from international leaders and concerns about potential price increases for consumers. In the NBC News interview, Trump said his permanent tariffs on foreign-made automobiles would be a boost to U.S.-domiciled factories and was confident the move would lead to increased sales of American-made cars.
