Donald Trump threatens 25% tariffs on cars, pharmaceuticals and semiconductors

Trump has announced a broad range of levies on some of the biggest US trading partners since taking office in January, arguing that they will help tackle unfair practices -- and in some cases using the threats to influence policy.

He recently pledged 10 percent duties on all goods coming from China, and 25 on steel and aluminum imports.

At his Mar-a-Lago resort in Florida, he told reporters that tariffs on the automobile industry will "be in the neighborhood of 25 percent," with specifics to come around April 2.
