US trade representative Jamieson Greer has a level-headed reputation but commerce secretary Howard Lutnick and White House adviser Peter Navarro also have key roles

Having reportedly read Victor Hugo’s Les Misérables, in French, during a military tour of duty in Iraq, Jamieson Greer considered himself an unlikely target for accusations of francophobia.

But Donald Trump’s US trade representative, hitherto one of the president’s less high-profile cabinet members, found himself in that uncomfortable position amid the acrimonious collapse of bilateral trade talks with Canada that now threatens to degenerate into an all-out trade war between the two close trading partners whose economies are tightly intertwined.

Meanwhile, Trump posts video of himself kicking over a Lake Ontario sign and replacing it with Lake America sign

Donald Trump and Canada continued a verbal duel on Saturday over the US government’s administrative renaming of Lake Ontario, with the Ontario premier erecting a giant sign saying “Lake Ontario. Now and Always” – and the American president posting a video of him tearing down an avatar of that sign, erecting a replacement saying Lake America, and dancing to YMCA.

Rhetoric over the naming of Lake Ontario is the public face of an escalating trade dispute between the US and its northern neighbor involving a 50% US tariff on Canadian steel and retaliatory tariffs from Ottawa.

There’s little optimism about treasury secretary’s ability to handle Trump’s tariffs, Iran sanctions and colossal US debt

History remembers Gen Dwight Eisenhower, the supreme commander of the allied forces in Europe during the second world war, for his role in the D-day invasion of Normandy. Whether Scott Bessent will achieve similar posterity as the face of the “economic D-day” in Iran remains to be seen.

The US treasury secretary, already trying to manage a $40tn national debt pile, this week took charge of Donald Trump’s effort to reverse-engineer his war of choice. Whereas the US would typically take on an adversary with diplomacy, sanctions and military force, in that order, the US president started with a six-month bombing campaign and now hopes that economic isolation can finish the job.

Ignore Iran, the Epstein files, and your wallet – not to mention Trump’s plummeting approval ratings

Don’t mention the war! Or the economy, for that matter. Or the Epstein files. Or Natalie Harp. Or “affordability”, which, as Donald Trump recently said at a rally, is a word that was “never used” by the media before he took office. Best not to talk about anything that affects ordinary people or embarrasses the president, really. Instead, let’s all rejoice in Trump’s latest triumph: renaming Lake Ontario, which is shared by Canada and the US, as Lake America.

On Thursday, Trump signed an executive order directing federal agencies to America-fy the lake’s name on US maps and documents, which is an excellent use of time and resources. I suppose we can at least be thankful that the president, who is trying to slap his own name on everything from airports to the Kennedy Center, didn’t decree that the body of water be called Lake Trump.

Avoiding US goods and services – from tech to whisky to air travel – has forced many to find a new way of living

For William McDonald, 38, a diesel mechanic from Thunder Bay, Ontario, “Canadian is always the first choice,” even if it means his weekly bills are higher.

“As soon as Trump started putting those tariffs on in February [last year], I started boycotting US goods,” he said. “Avoiding American products has driven my costs up, and I’m still happy to do it.

US president says US will have ‘majority’ control of 65bn barrels of proven oil reserves

Donald Trump announced Friday a new US oil agreement with Venezuela’s interim president Delcy Rodríguez, saying the US will have “majority” control of 65bn barrels of proven oil reserves.

The terms of the agreement remain to be seen, but the US president said on his social-media platform that it had been brokered “through a partnership with ⁠private business” by his secretary of state, Marco Rubio, and defense secretary, Pete Hegseth.

President Trump dismissed suggestions that the CIA director was sent to Moscow over concerns that Russia could test NATO’s resolve

Terrified of being seen as a loser, Donald Trump is nonsensically lashing out – even against our old friend Canada

I’m still grieving Dolly Parton. I never met her and always wanted to. She was almost exactly my age and my height and had values I deeply admired. Her death leaves a hole in the firmament.

Which brings me to the person whose values are as far from Dolly Parton’s as any human could possibly be and still claim to be human. I’m referring, of course, to the current occupant of the Oval Office.

Unpopular new policy comes as midterms loom and control of Congress could be decided by several Michigan races

Every day $1bn worth of goods crosses the river dividing Detroit, Michigan, and Windsor, Ontario, two largely blue-collar US and Canadian cities that have come to act as one in the creation of North America’s auto industry.

News this week of Donald Trump’s escalating trade spat with Canada has everyone worried. Political and economic leaders and observers labeled the move an act of “hubris” , blamed Trump’s “ego”, and called the escalation “insanity”.

Mark Carney rejects attempt to rename lake as did several US governors, with Tony Evers mocking the move

• US politics live – latest updates

Donald Trump signed an executive order on Thursday directing the federal government to rename Lake Ontario, making it Lake America, amid his escalating trade war with Canada.

The order directs federal agencies to adopt the name-change on US maps, documents and databases. But Trump has no authority to rename Canada’s portion of the lake, nor to compel Canada, international legal bodies, international mapmakers, or the rest of the world to adopt a new name.

The US president expected Ottawa to bow to tariff demands, but Canada is striking back – and it could cost Americans

Earlier this year, a survey found that Canada, along with Switzerland, was the best-liked country in the world. We all know this kind of polling is about as scientific as a high school popularity contest, but at least anecdotally, Canadians have a reputation for being friendly and welcoming, respectful and polite. Many people would find it difficult to dislike Canadians.

But not Donald Trump, who in a “hold my beer” moment this week demonstrated that he, at least, finds it easy to resent Canadians. The US president called the country “difficult and unreasonable”, and in a particularly hysterical moment, threatened to rename a lake, after trade talks collapsed.

The quiet-spoken Canadian prime minister has spoken unutterable truths

Is it perhaps a sign of the times that Mark Carney, the prime minister of Canada, has become a thrilling orator? A sober banker, he speaks calmly, without many vocal inflections. We expect Canadians to be somewhat flat; even a little boring, and yet Carney has already delivered two remarkable speeches in 2026, and the year is far from over.

The first, at Davos, described a “rupture in the world order”, and “the end of a pleasant fiction”. By that, he meant that the world could no longer depend on the United States to lead the Pax Americana that has largely kept the peace since the end of the second world war.

Paper products among hardest-hit sectors after trade negotiations broke down, with 25-50% tariffs estimated

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

Using the bathroom or having a cry is about to become more expensive for North Americans as the US and Canada enter a full-fledged trade war that threatens to flush away decades of peaceful trading between the two nations.

After trade negotiations broke down between the two countries last weekend, Mark Carney, the Canadian prime minister, vowed to match US tariffs “dollar for dollar” and unveiled a list of nearly 900 American goods that will face 25% to 50% tariffs starting on 8 September.

Cristy Maryori Villafranca-Trejo, deported to Honduras, is latest military spouse to face removal amid Trump 2.0

The wife of an active-duty US soldier was deported on Monday to her native Honduras, according to her family and the federal Department of Homeland Security (DHS).

Cristy Maryori Villafranca-Trejo is at least the seventh spouse or parent of an active-duty US soldier to be deported under the immigration crackdown during Donald Trump’s second presidency.

Announcement of tariffs on $20bn worth of US goods follows through on Mark Carney's vow to match US tariffs 'dollar for dollar'

US president has been obsessed with restricting the ability to vote by mail, despite using it himself. Plus, why we are still fascinated with Meg from the White Stripes

Good morning. The US supreme court has sided with Donald Trump in his effort to crack down on mail-in voting, though it is unclear whether or not his administration will be able to take action before the midterm elections in November. The court’s justices voted 6-3 along ideological lines to lift an injunction that a judge in Massachusetts had placed in June on an executive order issued by the president. But a second injunction remains in place, and the ruling leaves room for legal challenges.

Trump has repeatedly likened voting by mail to cheating, despite his own use of it and overwhelming evidence that the system is secure. In March he ordered the government to create a “state citizenship list” of eligible voters, requiring that mail-in ballots only be delivered to people on that list. He also directed the justice department to prioritise investigations and prosecutions of state and local election officials who issue ballots to people deemed ineligible to vote in federal elections.

What did the dissenting judges say? In a blistering dissent, Justice Ketanji Brown Jackson wrote that the decision “needlessly injects chaos and uncertainty into the upcoming midterm elections”.

How have rights organisations reacted? The president of the National Association for the Advancement of Colored People, Derrick Johnson, said: “Let this ruling be a reminder that democracy is never, ever guaranteed. We have to fight for it, we have to fight to keep it and we have to protect the rights we do have within it … they are trying to do everything they possibly can to make it difficult for you to vote.”

How has Canada reacted? The country’s prime minister, Mark Carney, told reporters that Trump’s announcement was largely expected. “It’s not a surprise for us that the US would take some form of reprisal to our response to their unjustified tariff,” he said. Carney has vowed to match the American tariffs “dollar for dollar”, and said Canada could not accept any proposed trade deal that would weaken French language protections.

A fundamental rupture in the values that have united North America is not a problem that can be wished away: this is a warning to the western alliance

The Canadians are exceedingly angry. I realise this can sometimes be difficult for foreigners to deduce, given our national struggle to express the full range of human emotion outside ice hockey riots. However, let me assure you that the prime minister Canadians saw take the stage on Saturday morning in the wake of the collapse in trade negotiations with the US was a Mark Carney practically vibrating with fury.

“You’re at war when you get attacked. We got attacked,” he said, in a rare press conference that was as candid and clear as he ever tends to be. “That’s fine … We’ve got the reserves, we’ve got the resilience, we’ve got the plan, we’ve got the focus. We’re gonna respond, we’re going to focus on what we can control and what we’re going to build.”

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.

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.

Breakdown shows Washington now prioritises its own interests over any semblance of shared economic ground

• ‘No more!!!’: Trump lashes out after US-Canada talks devolve into trade war

The calamitous collapse of trade negotiations between Canada and the United States is a warning to nations worldwide that pursuing any kind of dialogue with the current US administration is doomed at the outset, according to observers who say this recent episode indicates seeking a fair deal is futile.

Andrea Lawlor, an associate professor of political science at McMaster University in Ontario, said: “No matter the closeness of the historical relationship, the American administration has signalled that it now prioritises its interests above those of some sort of global economic coordination or harmony.

Audio recording of US vice-president apparently made at New York fundraiser and shared with Canadian Press

Leaked audio from a private event has reportedly captured the US vice-president, JD Vance, mocking Canada for apparently capitulating in a trade deal and taunting the prime minister, Mark Carney, for trying to “out-tough” Donald Trump.

The recording, which was reportedly made at a fundraiser and shared with the Canadian Press, comes in the last stretch of a difficult negotiation in which the US president has threatened to impose 50% tariffs on Canada.

With plentiful jobs and community support, one Mexico City neighbourhood has become a haven for those who have lived much of their lives in the US

With its wide avenues lined with tall palm trees, its quaint cafes and old-school cantinas, as well as the mix of English and Spanish spoken on the street, the Tabacalera neighborhood in downtown Mexico City has a certain US feel – so much so that it is has become known as Little LA.

The nickname is about more than appearances, however. In recent years, this corner of the metropolis has become a haven for many Mexicans deported from the US, particularly those who spent years or decades living across the border and for whom Mexico feels like a foreign country. In Little LA, they have found a more familiar place to belong.

US president delays 50% tariffs by three days, and says contentious oil project ‘may be awoken from the grave’

Canada has temporarily avoided a bruising 50% US tariff, reaching a Tuesday-evening agreement with Trump administration officials hours before a hike that would have affected $20bn worth of goods was set to take effect.

Donald Trump posted late on Tuesday on social media that he had paused the tariffs for three days “based on the fact that Canada and the USA, subject to the finalization of documents, have a DEAL!”

Conor Kennedy said he was ‘willing to die’ in Ukraine after signing up to fight in 2022. Four years later he has been accused of acting as a mercenary by a Russian court
