The president has claimed any decision against him would ‘destroy’ the ‘financial fabric of our country’

Donald Trump has upended the global economy, imposing steep tariffs on US allies and rivals, dismissing fears of higher prices, and promising his strategy will yield a new “golden age”. All the president needs to do now is prove he’s allowed to do it.

Legal experts say he may face an uphill battle.

In May, the US court of international trade ruled that the bulk of Trump’s tariffs “exceed any authority granted to the president”. And last Friday, the US court of appeals for the federal circuit ruled that Trump’s levies “assert an expansive authority that is beyond the express limitations” of the law his administration has leaned on.

Now Trump is taking the case to the supreme court, claiming any decision against him would “destroy” the US.
