Both conservative and liberal US supreme court justices have voiced skepticism over the Trump administration’s justification for tariffs

• US supreme court appears skeptical over legality of Trump tariffs

Here’s a look at some of the pictures from New York, as Zohran Mamdani was elected the next mayor of the city.

In a short while, we’ll hear from Donald Trump when he hosts a breakfast with Republican senators at the White House. As we noted earlier, the president had choice words about Mamdani’s victory in New York, and other Democratic wins across the country – including the gubernatorial races in Virginia and New Jersey.

Looking ahead, on Wednesday, the supreme court will hear arguments on whether Donald Trump’s sweeping tariffs on dozens of countries are legal. It’s set to be one of the most consequential rulings on the expanse of Trump’s presidential power in his second term.

My colleague, Eduardo Porter, has this helpful breakdown on the question at the heart of this case. A dozen states have challenged the president’s contention that the International Emergency Economic Powers Act (IEEPA) of 1977 gives him the power to impose tariffs on imports from every country in the world to defend the nation from a several “threats” facing the US.

Justices will focus much of their attention on whether IEEPA authorizes the president to levy a tariff – a word that is not mentioned in the text of the law and is, moreover, a form of taxation, over which, per the constitution, Congress has exclusive power.

IEEPA gives the president authority “to deal with any unusual and extraordinary threat, which has its source in whole or substantial part outside the United States, to the national security, foreign policy, or economy of the United States, if the president declares a national emergency with respect to such threat”.
