U.S. President Donald Trump is expected to find a workaround after suffering a major blow to a core part of his economic agenda.

A US federal court has blocked President Donald Trump's sweeping tariffs, in a major blow to a key component of his economic policies. The Court of International Trade ruled that an emergency law invoked by the White House did not give the president unilateral authority to impose tariffs on nearly every country.

The Administration has filed an appeal after it was dealt a major blow that would invalidate most of its global tariffs.
