The state department will revoke B1 and B2 visas issued between 2016 and 2026, whose holders have sought or are now seeking asylum

Donald Trump’s administration said on Monday it planned to revoke the non-immigrant visas of foreigners who have applied for or are currently seeking asylum status in the US, marking its latest step in a sweeping immigration crackdown.

A state department spokesperson said it was coordinating with the Department of Homeland Security (DHS) “to identify and revoke the non-immigrant visas of foreigners who have come to the United States claiming to be short-term visitors, but then file for asylum to stay here permanently”.

Justices’ ruling comes after lower courts had blocked president’s election order ahead of November midterms

The US supreme court sided with Donald Trump on Monday in his effort to crack down on mail-in voting, though it remains unclear if his administration can take action ahead of the midterm elections in November.

Justices on the court voted 6-3 along ideological lines to lift an injunction from June that a judge in Massachusetts placed on an executive order issued by the president. But a second injunction remains in place and the ruling leaves room for legal challenges.

Move is latest deterioration in trade relations between neighbors with historically strong economic ties

Donald Trump announced a new 50% tariff on automobiles and crucial raw materials from Canada, the latest deterioration in trade relations between the two neighbors with historically strong economic ties.

The US president said that the increased tariffs would start on 1 January 2027 on all cars, trucks, automobile parts and steel. He also derided the nation’s tariffs on American farmers, writing on social media that Canada has been “ripping off” the US “for years”.

Prime minister praised for rejecting US trade proposal as Trump shows little interest in retreating from dispute

• Are you a Canadian boycotting US products? We’d like to hear from you

Mark Carney said on Monday that while American negotiators saw the French language in Canada as an “irritant … in Quebec, these are rights,” days after receiving widespread praise from political leaders for rejecting a US trade proposal that many perceived as weakening the country’s Francophone culture.

The prime minister’s remarks came hours after the US president, Donald Trump, showed little interest in retreating from the spat, posting on social media that Canada had been “ripping off the United States of America for years” and threatening a swath of new, economically devastating tariffs on cars and trucks.

Exclusive: internal correspondence reveals USCIS anti-fraud officers shifted on to two ‘high-priority’ initiatives

All US immigration officers working for a key anti-fraud unit have been reassigned by the Trump administration to focus on screening South African refugees and alleged “unlawful” voters.

Fraud Detection and National Security Directorate (FDNS) immigration officers have been shifted full-time on to two “high-priority” initiatives, according to internal correspondence seen by the Guardian, leaving US Citizenship and Immigration Services (USCIS) unable to provide officers to train asylum officers in “the near future”.

The president’s border wall plan could damage or destroy ‘the oldest-known books in North America’

On an overcast summer morning, Carolyn Boyd, an archeologist at Texas State University, stood at the foot of a cave in west Texas, looking up toward a series of towering murals painted on a rock wall. Three massive human-like figures soared toward an overhang that had sheltered the painting from the elements since they were drawn here perhaps 4,000 years ago.

An artist herself, Boyd knows how hard it would have been to paint these long, crisp lines. Before starting, the bands of Indigenous hunter-gatherers who lived in this west Texas valley, where the Pecos River empties into the Rio Grande, would have spent weeks pulverizing gypsum, hematite, limonite and manganese to make paint. They would have gathered massive quantities of sotol stalks to fold its fibers into scaffolding. The painting itself would have required teamwork and precision, with people at the bottom guiding artists on the wall as they painted figures stretching up to 30ft tall.

The US is scooping up treasury bonds in an effort to raise their price and push yields down – but it’s not working

The bond market is driving the Trump administration crazy. Last week, the treasury secretary, Scott Bessent, announced that the government would sharply ramp up its purchase of treasury bonds, in an effort to raise their price and thus push down their yield, which amounts to the interest rate the government pays on its debt.

It didn’t quite work as planned. Yields on treasurys fell after Bessent’s bond market intervention but soon bounced back. By Friday afternoon, the yield on the 10-year treasury was back near where it was before the secretary’s announcement. The yield on the 30-year bond was again trading around its highest level in 20 years or more.
