On Monday, the White House hit back at the latest challenge to Trump's tariffs, arguing the government move was legal. "Section 301 tariffs have proven to be a legally durable tool since the President's first term, and they remain so now." "The Plaintiff States oppose forced labour in all its forms and support protections for workers around the globe. But the Administration cannot use forced labour as a pretext to continue its illegal tariff scheme." Trump's separate sector-specific tariffs – imposed under different legal authorities on steel, automobiles and other goods -- have been unaffected by recent legal challenges.
