Trump to join White House press briefing
We’ll be hearing from White House press secretary Karoline Leavitt in a short while, where she will brief reporters on Donald Trump’s first year back in office and will no doubt face questions on his preoccupation with Greenland. Per the press pool, the president will also be there. We’ll bring you all the key lines here, so stay tuned.

There was no debate about record crowd sizes this time. With the temperature plunging to 27F (-3C) and a wind chill making it feel far colder, Donald Trump’s second inauguration was held in the rotunda at the US Capitol in Washington on 20 January 2025.
The great and the good of the political elite were there, including former presidents Bill Clinton, George W Bush and Barack Obama and outgoing president Joe Biden. So were tech oligarchs such as Jeff Bezos, Tim Cook, Elon Musk and Mark Zuckerberg. At 12.10pm, they listened intently as Trump began a half-hour-long inaugural address.
The 47th president painted a bleak picture of America as a country where government was suffering a crisis of trust, failing to defend national borders and stumbling from catastrophe to catastrophe abroad. Reflecting on how he had narrowly escaped assassination, Trump declared:
I was saved by God to make America great again.
He promised a flurry of executive orders and made bold promises about immigration, the economy and America’s standing in the world. Here is a review of 10 key pledges – and what happened in the year since:

Andrew Roth
California governor Gavin Newsom has decried Europeans for their “complicity” in failing to stand up to Donald Trump’s demands that he be allowed to buy or annex Greenland.
Newsom, a frontrunner among Democratic candidates for president in 2028, told reporters at the World Economic Forum in Davos earlier today that Europeans were being “played” by Trump and that their efforts to negotiate with him were “not diplomacy, it’s stupidity”.
It’s time to buck up, it’s time to get serious and stop being complicit. I can’t take this complicity. People rolling over. I should have brought kneepads for all the world leaders … this is pathetic.
Newsom regularly suggests that US politicians who cosy up to Trump should be given kneepads – making it easier to kneel – and he sells them on his website. “For all your groveling to Trump needs now in Republican red,” reads the advertisement for the kneepads, which bear a copy of Trump’s signature. “For the low low price of your soul.”

Jakub Krupa
Donald Trump has just posted on Truth Social claiming that “no single person, or president, has done more for Nato than president Donald J. Trump”.
He added:
“If I didn’t come along, there would be no Nato right now!!!
It would have been in the ash heap of History.
Sad, but TRUE!!! President DJT”
Somewhat confusingly, he also earlier “re-Truthed” a post claiming that China and Russia were “the boogeymen,” and “the real threat” was from the UN, Nato, and Islam.
Republican congresswoman officially launches Louisiana Senate bid after Trump’s endorsement
Louisiana congresswoman Julia Letlow officially announced her bid for Senate on Tuesday after receiving a “complete and total” social media endorsement from Donald Trump over the weekend.
Letlow, a Republican, is issuing a primary challenge to two-term GOP incumbent Bill Cassidy.
“I know Julia well, have seen her tested at the highest and most difficult levels, and she is a TOTAL WINNER!,” the president wrote on Truth Social, after hearing that Letlow was considering entering the Louisiana Senate race. “RUN, JULIA, RUN!!!”
A reminder that Cassidy, a former physician who serves as chair of the Senate health, labor and pensions committee, was one of seven senators who voted to convict the president of inciting an insurrection during his second impeachment trial after the 2021 Capitol riots.
In the year since Trump returned to the White House, Cassidy has sought to avoid the president’s ire by casting the deciding vote to confirmhealth secretary Robert F Kennedy Jr. This, despite the lawmaker’s numerous misgivings about Kennedy’s past comments undermining the safety and efficacy of vaccines.
Cassidy has since pushed back against Kennedy’s handling of the Department of Health and Human Services (HHS), including at a bipartisan committee hearing in September when the senator accused the health secretary of “effectively denying people the vaccine”, after the Food and Drug Administration (FDA) approved new Covid-19 inoculations but placed restrictions on who would be able to access them.
In a video announcement on Tuesday, explaining her decision to enter the race, Letlow said that in “a state as conservative as ours [Louisiana], we shouldn’t have to wonder how our senator will vote when the pressure is on.”
The lawmaker, who won a 2021 special election after her husband – Luke Letlow – died from complications of Covid-19 five days before he was set to be sworn into office, thanked Donald Trump for his backing and praised his policy agenda.
“Our president is keeping his promises,” she said. “I have fought alongside President Trump to put America first, standing up for our parents, securing our borders, supporting law enforcement, rooting out waste, fraud and abuse that drives up inflation, and fighting to fix an education system to focus on woke ideology instead of teaching.”
In response to Letlow’s announcement, Cassidy said that he had heard from the congresswoman this morning – when she called him to say she was running for office. “She said she respected me and that I had done a good job. I will continue to do a good job when I win re-election. I am a conservative who wakes up every morning thinking about how to make Louisiana and the United States a better place to live,” Cassidy said in a statement.

Three cardinals in the US Catholic church have criticized the Trump administration’s foreign policy, saying its push to obtain or otherwise seize Greenland, recent military action in Venezuela, and cuts to humanitarian aid risk “destroying international relations and plunging the world into incalculable suffering”.
“Our country’s moral role in confronting evil around the world, sustaining the right to life and human dignity, and supporting religious liberty are all under examination,” said a joint statement from Blase Cupich, Robert McElroy and Joseph Tobin, respectively the archbishops of Chicago, Washington DC, and Newark, New Jersey.
“And the building of just and sustainable peace, so crucial to humanity’s wellbeing now and in the future, is being reduced to partisan categories that encourage polarization and destructive policies,” it added.
Without naming Donald Trump, the statement on Monday continued: “We seek a foreign policy that respects and advances the right to human life, religious liberty, and the enhancement of human dignity throughout the world, especially through economic assistance.”
Supreme court does not issue decision on legality of Trump’s global tariffs
The supreme court did not issue a decision today on the legality of Donald Trump’s sweeping global tariffs.
It’s not immediately clear the next date the court will issue opinions.
Two boxes have been brought out at the supreme court, which means there could be up to four decisions released today.
As we wait on today’s opinions from the supreme court, it’s worth remembering that justices on the bench appeared skeptical of the administration’s arguments justifying the use of the International Emergency Economic Powers Act (IEEPA) to slap duties on dozens of countries, citing a national emergency. A reminder that the ability to institute taxes is a power normally only afforded to Congress.
Per my last post, my colleagues Jakub Krupa and Yohannes Lowe are reporting the latest developments out of Europe at our dedicate live blog. While Graeme Wearden is providing updates from Davos on our business blog.
Graeme notes that at an earlier press conference today, treasury secretary Scott Bessent said that there are four “fantastic candidates” for Federal Reserve chair. He expects the Trump administration to make an announcement “maybe as early as next week”.
In a spree of Truth Social posts overnight, Donald Trump posted an altered image of himself, planting a US flag in Greenland, alongside JD Vance and secretary of state Marco Rubio.
In another post, also featuring a doctored photo, it shows Trump behind the resolute desk speaking to European leaders while he shows off a map that shows an American flag covering the US, Canada and Greenland.
Trump’s campaign to acquire the autonomous territory, that remains part of the Kingdom of Denmark, has reached fever pitch in recent days after he threatened tariffs against allied countries who have spoken out against his moves on Greenland. We can expect more friction as the president heads to Davos today.
Earlier, European Commission president Ursula von der Leyen repeatedly criticized Trump for his levy threats, saying they would be “a mistake” and could send the relations into “a downward spiral” that benefits geopolitical rivals. She also pledged her solidarity and support with Denmark and Greenland.
Second man dies at Texas ICE detention facility in two weeks
Victoria Bekiempis
A second man being held at a US immigration detention facility in Texas has died in two weeks, US Immigration and Customs Enforcement (ICE) said on Monday.
Victor Manuel Diaz, 36, originally from Nicaragua, was found “unconscious and unresponsive in his room” on 14 January at the Camp East Montana detention facility in El Paso, ICE said in a press release.
“They immediately notified contract medical staff on site to conduct life saving measures,” it said, adding that emergency medical technicians arrived to the facility but could not revive Diaz, who was pronounced dead just after 4pm. ICE asserted that Diaz “died of a presumed suicide” but that the “official cause of his death remains under investigation”.
Diaz was detained on 6 January during the Trump administration’s controversial deportation blitz in Minneapolis, Minnesota. He initially entered the US through the Mexican border in March of 2024, when border patrol agents picked him up and he was given a court date with an immigration judge, then released on parole.
On 26 August of last year an immigration judge ordered Diaz’s removal “in absentia”. ICE detained him on 12 January in order to deport him. The extensive tent facility is located on the Fort Bliss military base in El Paso …
Another man, Geraldo Lunas Campos, 55, who immigrated to the US from Cuba, died in the same detention camp on 3 January. ICE said Campos was “experiencing medical distress” and that staff provided emergency treatment in the hopes of saving him. His death is potentially being investigated as a homicide.

Judge refuses to block new DHS policy limiting Congress members’ access to ICE facilities
Yohannes Lowe
In other news, a federal judge has refused to temporarily block the Trump administration from enforcing a new policy requiring a week’s notice before members of Congress can visit – and thereby inspect – immigration detention facilities.
Judge Jia M. Cobb of the Federal District Court for the District of Columbia concluded that the Department of Homeland Security (DHS) didn’t violate an earlier court order when it reimposed a seven-day notice requirement for congressional oversight visits to Immigration and Customs Enforcement (ICE) facilities (you can read her judgment here).
Judge Cobb, an appointee of Democratic former president Joe Biden, had blocked a virtually identical policy by the DHS last month, citing a clause in the appropriations law that funds the department and requires facilities to be open to congressional scrutiny.
However, ICE reestablished the visitation policy on 8 January 2026, with the homeland security secretary, Kristi Noem, ordering the DHS to re-impose the seven-day notice requirement – but “exclusively with money appropriated by the (One Big Beautiful Bill Act),” not regular appropriations, effectively bypassing the previous court order.
The background to this is that last June, a dozen House Democrats who were blocked from visiting immigration detention facilities sued the Trump administration, accusing it of unlawfully obstructing their efforts to visit federal immigration detention centers.
Members of Congress had tried to visit the facilities amid reports of inhumane and unsanitary conditions. Thirty-two people died in ICE custody last year, the highest number of fatalities in two decades. At least five people have reportedly died in ICE custody so far this year.
In her ruling on Monday, Judge Cobb said the plaintiffs’ attorneys representing Democratic members of Congress used the wrong “procedural vehicle” to challenge the new policy and said the lawmakers would need to revise their complaint. She did not rule on the legality of the policy.
Donald Trump will head to the World Economic Forum in Davos, Switzerland later today.
He’ll be joining several of the ally countries that he’s been lambasting, and threatening with tariffs, in recent days over his longstanding goal to annex Greenland.
The president is due to leave the White House after a closed-door signing. We’ll bring you the latest in case he decides to speak to the press before he heads off.
Later today we’ll also hear from Karoline Leavitt when she holds a briefing for reporters at 1pm ET. We’ll be covering that and provide updates here.
US supreme court to hear challenge to Hawaii’s strict gun law
Eric Berger
Hawaii, which has some of the strictest gun laws in the United States, will see its regulations challenged before the supreme court on Tuesday.
The court will consider the legality of the state’s law that bans people from bringing firearms on private property open to the public unless they have permission from the property owner.
The case, Wolford v Lopez, was brought by three Maui residents with concealed-carry permits and a local gun group.
US supreme court ruling on Trump’s tariffs could come as early as Tuesday
Yohannes Lowe
Good morning, and welcome to our live coverage of US politics. The much-anticipated US supreme court ruling on the legality of Donald Trump’s tariffs is expected in the coming weeks, and possibly as early as Tuesday, according to the Reuters news agency.
Those challenging the tariffs, which include some small businesses and US states, argue the president exceeded his authority when imposing the sweeping levies last year.
Two lower courts have already found that the president did not have the authority to impose global tariffs, which were brought in using emergency powers allowing the president to issue immediate orders and bypass Congress.
The supreme court, which is dominated by conservative justices, could throw out the tariffs – the cornerstone of Trump’s economic agenda – and force the president to send refunds to the US importers that paid them.
But if the supreme court does rule Trump overstepped his authority under the International Emergency Economic Powers Act, or IEEPA, to impose the tariffs, the White House has other ways it can bring in import taxes.
In a 15 January interview with the NY Times published on Monday, the US trade representative, Jamieson Greer, said the administration would “start the next day” to replace the tariffs with other levies if the ruling went against Trump.
“The reality is the president is going to have tariffs as part of his trade policy going forward,” Greer said. Last week, Trump said it would be “a complete mess” if the court were to strike down his trade tariffs, which he said would be difficult to reverse because businesses and countries could claim refunds.
