Yesterday, the Supreme Court underscored a principle that's in part of the Constitution of the United States of America from the very beginning.

Even the most powerful president in the world cannot rewrite the Constitution to win an argument about economics.

24 hours ago, President Trump suffered a significant legal defeat on one of the defining

policies of his political identity, his tariffs. For years, Donald Trump described tariffs as a kind

of economic superpower, a way to punish foreign countries and rich Americans and raise money

for the government at the same time.

He said repeatedly that other nations were paying us trillions of dollars.

In his telling, tariffs were not just policy, they were proof that America could act alone

and quickly solve complicated global trade problems.

Yesterday, the Supreme Court rejected the legal basis for a specific group of those tariffs,

the sweeping import taxes that the president imposed using emergency economic powers.

These tariffs covered familiar goods like many everyday imported products and auto-related parts.

But in this case, the authority Trump used to impose those tariffs was designed for real emergencies

that allow a president to act quickly during a sudden economic or national crisis.

The court said those emergency powers cannot be stretched into a long-term substitute for Congress writing tax policy.

These were not traditional tariffs passed by Congress through normal trade laws.

Instead, they were broad taxes placed on many imported goods based on the president's claims of emergency authority.

In simple terms, the court concluded that emergency powers can't be used to impose what are essentially taxes unless Congress clearly allows it.

Donald Trump responded quickly, saying he's got a backup plan.

He initially said he would impose an additional 10% global tariff,

and he had some choice words for the Supreme Court justices who ruled against him.

Today I will sign in order to impose a 10% global tariff under Section 122 over and above are normal tariffs
