US President Donald Trump warned Sunday that no country would be "getting off the hook" on tariffs, as his administration suggested exemptions seen as favoring China would be short-lived.

President Trump’s “Liberation Day” tariffs came under their first major legal challenge Monday, brought by a libertarian public-interest firm that argues the president overstepped his authority. Trump’s April 2 announcement imposed a baseline 10 percent tariff on imports and targeted dozens of countries with higher “reciprocal” tariffs.
