The conservative majority of United States supreme court justices has been widely criticized for granting Donald Trump an increasing amount of leeway to wield his presidential power. On Wednesday, the court questioned one avenue of the president’s authority: his ability to impose sweeping global tariffs.
Justices heard oral arguments on the legality of the tariffs, with conservative justices expressing skepticism of the strength of the Trump administration’s position.
“The vehicle is the imposition of taxes on Americans, and that has always been a core power of Congress,” said Chief Justice John Roberts.
The arguments center on the International Emergency Economic Powers Act, or IEEPA, a 1977 law which in some circumstances grants the president authority to regulate or prohibit international transactions during a national emergency. Trump cited the law as he slapped steep duties on imports into the US.
About 40 legal briefs have been filed in opposition to the tariffs, including from the US Chamber of Commerce, the largest business lobby group in the US.

They appeared to be artificially generated, but the Guardian could not independently confirm.
Democrats celebrate while Republicans stew over Mamdani’s win
Left-leaning Americans awoke to a rare recent moment of political celebration with Democratic victories in several elections across the country, led by the election of Zohran Mamdani as the next mayor of New York, while Republicans breathlessly hailed the end of the country. Many Republicans’ immediate reaction was to attribute Mamdani’s win to an electorate overrepresented by immigrants, snidely implying they were not “real” Americans.
