US President Donald Trump warned that a court ruling against his proposed tariffs could lead to the “economic ruination” of the US, claiming it would allow foreign nations to exploit America.

The Trump administration has asked a U.S. appeals court to block a recent ruling declaring its sweeping tariffs illegal. The White House stated in an emergency motion to the D.C. Circuit Court of Appeals that stopping the tariffs poses a danger to crucial trade talks already underway with dozens of countries.
