Donald Trump has been urged to fire US Secretary of Defence Pete Hegseth following the leak of highly sensitive war plans – as national security adviser Mike Waltz said he took “full responsibility” for organising the group chat.
The conversation on the messaging app Signal between US officials, including vice presidentJD Vance and Mr Hegseth, was leaked to American journalist Jeffrey Goldberg, who was added to the chat in error.
Mr Waltz –who had mistakenly added Mr Goldberg to the Signal discussion – said: “I take full responsibility…I built the group.”
Democratic congressman Hakeem Jeffries, minority leader of the US House of Representatives, described Mr Hegseth as “the most unqualified Secretary of Defence in American history” and called for him to be sacked.
“His continued presence in the top position of leadership at the Pentagon threatens the nation’s security and puts our brave men and women in uniform throughout the world in danger,” he wrote.

Speaking from the White House, Mr Trump downplayed the incident and said he believed the chat contained “no classified information”.
“They were using an app, as I understand it, that a lot of people in government use, a lot of people in the media use,” he told reporters.
Trump expressed support for Mr Waltz, telling NBC News his national security adviser “has learned a lesson, and he’s a good man”.

How serious is US chat breach?
The US president said officials would “probably” not use Signal any longer but did not agree to a full investigation of what Democrats have called a major security breach which required high-level resignations.
Included in the conversation on Signal were Mr Vance, Secretary of State Marco Rubio and Mr Hegseth.
Director of National Intelligence Tulsi Gabbard and CIA director John Ratcliffe – who were both also in the chat – testified before the Senate Intelligence Committee on Tuesday that no classified material was shared.

But Democratic senators have voiced scepticism, noting that the journalist, The Atlantic editor-in-chief Jeffrey Goldberg, reported Mr Hegseth posted operational details “including information about targets, weapons the US would be deploying, and attack sequencing”.
Republican majority leader, John Thune, said on Tuesday he expected the Senate Armed Services Committee to look into Trump administration officials’ use of Signal.
Meanwhile, the White House has mostly attacked the journalist responsible for the original story instead of admitting culpability. The integrity of Mr Goldberg has been repeatedly called into question.
Posting on X, White House press secretary Karoline Leavitt accused Mr Goldberg of sensationalising the story, and White House communications director Steven Cheung called the media coverage of the security breach a “witch hunt”.
If a British defence minister was found to have shared details about a live military operation in an unofficial messaging group with colleagues, they would be sacked.
That President Donald Trump has tried to dismiss the revelation that his top defence and security team not only did just that but accidentally included a journalist in the chat will be watched with deepening horror by US allies and growing glee by American enemies.
In public, the UK government is still insisting security ties with the US are as strong as ever.
But in private there will doubtless be horror – though perhaps not surprise – within Whitehall at this extraordinary lapse in the most basic operational security by the president’s national security adviser, defence secretary, national intelligence chief and even the boss of the CIA.
Any information about plans to – for example – launch bombing raids against Iranian-backed Houthi militants in Yemen would ordinarily only be shared on specially designated government systems that ensure classified information is secure.
The fact that Mike Waltz, the national security adviser, felt it was acceptable to set up a group on the commercial messaging app Signal – which does provide encryption but is only as secure as the device that it is being used on (so not secure at all if a mobile phone or laptop is compromised) – to discuss plans to attack the Houthis is bad enough.
The Atlantic has hit back, dismissing those claims. “Attempts to disparage and discredit The Atlantic, our editor, and our reporting follow an obvious playbook by elected officials and others in power who are hostile to journalists and the First Amendment rights of all Americans,” it said in a statement.
Mr Hegseth told reporters on Monday no one had texted war plans – prompting Mr Goldberg to call those comments a lie during an interview on CNN.

It remains unclear why the officials chose to chat via Signal instead of secure government channels typically used for sensitive discussions.
The Pentagon reportedly warned of a known vulnerability on the Signal chat app, in an email sent out prior to the publication of The Atlantic article, according to reports by Sky News’ US partner network NBC News.
The email reported: “Russia-aligned threat groups are actively targeting the Signal Messenger application of individuals likely to exchange sensitive military and government communications related to the war in Ukraine”.
Employees were told the vulnerability could be mitigated by updating to the latest version of the app and applying proper settings.
JD Vance has told Denmark it has “not done a good job” with Greenland during a visit to the territory – as President Donald Trump repeated his call for the US to take over the island.
Vice President Vance, his wife Usha and other senior US officials arrived at an American military base in Greenland, the semi-autonomous territory that has been a part of Denmark for more than 600 years.
“Our message to Denmark is very simple: you have not done a good job by the people of Greenland,” Mr Vance said.
“You have underinvested in the people of Greenland, and you have underinvested in the security architecture of this incredible, beautiful landmass filled with incredible people.
“We need to ensure that America is leading in the Arctic.”
Shortly before Mr Vance spoke from Greenland on Friday, Mr Trump continued his threats of taking over the territory, saying: “We need Greenland, very importantly, for international security.
“We have to have Greenland. It’s not a question of you think we can do without it – we can’t.”

‘We need Greenland’ says Trump
The one-day visit to the US Space Force outpost at Pituffik – located on the northwest coast of the territory – has avoided violating potential diplomatic taboos of a state sending a delegation to another country, without an invitation.
The trip had been scaled back after locals were angered that the original itinerary was made without consulting them – particularly in light of Mr Trump’s repeated claims that the US should control Greenland.
Speaking to soldiers at the US base, Mr Vance claimed Denmark – and Europe by extension – has failed to protect the region.

He said: “This place, this base, this surrounding area, is less secure than it was 30-40 years ago, as some of our allies have not kept up…
“Europe (has) not kept pace… with military spending, and Denmark has not kept pace in devoting the resources necessary to keep this base, to keep our troops, and in my view to keep the people of Greenland safe from a lot of aggressive incursions from Russia, China, and other nations.”
Mr Vance said Mr Trump was “a president of peace”, adding: “We respect the self-determination of Greenlanders, we believe in the self-determination of the population of Greenland.”
Asked if plans have been drafted to use military force to take over Greenland, he indicated the White House planned to wait for the people of the territory to vote for self-determination before acting.
“What the president has said… is that we need to have more of a position in Greenland,” he added.

Greenland is the world’s largest island, with a population of 57,000, and is also a founding member of NATO.
Straddling the Arctic circle between the US, Russia and Europe, the island offers a unique geopolitical advantage that America has eyed for more than 150 years.
Earlier this week, Russian President Vladimir Putin said he was not surprised the US wants control of Greenland given its long-time interest in the mineral-rich territory.
“It can look surprising only at first glance and it would be wrong to believe that this is some sort of extravagant talk by the current US administration,” Mr Putin said.
Two events this week will give Greenland and friends in Europe a juddering sense of alarm.
From the West, the US vice president JD Vance has landed for a controversial visit, despatched by a president openly talking of annexation.
From the East a speech from a Russian leader hinting at carving up the Arctic and its vast mineral wealth with Moscow’s new friends in Washington.

In a closely watched speech, Vladimir Putin seemed to give Donald Trump’splans to seize Greenland the green light.
They were “serious”, he said, and “have deep historical roots”.
Kremlin officials went further saying Russia was open to cooperating with America to exploit the Arctic with “joint investment”.
The Arctic is a huge prize. Its vast mineral wealth is increasingly accessible thanks to climate change.

Yet another challenge for Europe
The threat of Russia and America jointly exploiting the Arctic in a great power carve-up is yet another challenge for Europe in this new Trumpian world order. And Greenland is caught in the middle.
Mr Trump has said he thinks the American annexation of Greenland “will happen”.

What do Greenlanders make of Trump?
He said so with breezy nonchalance in front of NATO’s secretary general in the White House as if taking another alliance member’s territory was entirely normal.
Astonishingly NATO secretary general Mark Rutte did not push back at the idea.
But it seems the Trump administration is determined one way or another to acquire more territory and Greenland seems top of the list.
And its president may have been persuaded by Mr Putin it is in his best interests to share the world with Russia, whatever that means for America’s allies.
US congresswoman Marjorie Taylor Greene hit the headlines this week when she told Sky’s US correspondent Martha Kelner to “go back to your own country”.
It was the latest controversy in a political career for the Republican firebrand – a staunch supporter of US President Donald Trump and his Make America Great Again (MAGA) movement.
