Donald Trump has said he is considering “taking away” the US citizenship of actress and comedian Rosie O’Donnell, despite a Supreme Court ruling that expressly prohibits a government from doing so.

In a post on Truth Social on Saturday, the US president said: “Because of the fact that Rosie O’Donnell is not in the best interests of our Great Country, I am giving serious consideration to taking away her Citizenship.”

He also labelled O’Donnell, who has moved to Ireland, as a “threat to humanity” and said she should “remain in the wonderful country of Ireland, if they want her”.

O’Donnell responded on Instagram by posting a photograph of Mr Trump with Jeffrey Epstein.

“You are everything that is wrong with America and I’m everything you hate about what’s still right with it,” she wrote in the caption.

“I’m not yours to silence. I never was.”

O’Donnell moved to Ireland with her 12-year-old son in January after Mr Trump had secured a second term.

She has said she’s in the process of obtaining Irish citizenship based on family lineage and that she would only return to the US “when it is safe for all citizens to have equal rights there in America”.

O’Donnell and the US president have criticised each other publicly for years, in an often-bitter back-and-forth that predates Mr Trump’s move into politics.

This is just the latest threat by the president to revoke the citizenship of someone he has disagreed with, most recently his former ally Elon Musk.

But the two situations are different as while Musk was born in South Africa, O’Donnell was born in the US and has a constitutional right to American citizenship.

Amanda Frost, a law professor at the University of Virginia School of Law, said the Supreme Court ruled in a 1967 case that the fourteenth amendment of the constitution prevents the government from taking away citizenship.

“The president has no authority to take away the citizenship of a native-born US citizen,” he added.

“In short, we are nation founded on the principle that the people choose the government; the government cannot choose the people.”

It is “shameful” that black boys growing up in London are “far more likely” to die than white boys, Metropolitan Police chief Sir Mark Rowley has told Sky News.

In a wide-ranging interview with Sunday Morning with Trevor Phillips, the commissioner said that relations with minority communities are “difficult for us”, while also speaking about the state of the justice system and the size of the police force.

Sir Mark, who came out of retirement to become head of the UK’s largest police force in 2022, said: “We can’t pretend otherwise that we’ve got a history between policing and black communities where policing has got a lot wrong.

“And we get a lot more right today, but we do still make mistakes. That’s not in doubt. I’m being as relentless in that as it can be.”

He said the “vast majority” of the force are “good people”.

However, he added: “But that legacy, combined with the tragedy that some of this crime falls most heavily in black communities, that creates a real problem because the legacy creates concern.”

Sir Mark, who also leads the UK’s counter-terrorism policing, said black boys growing up in London “are far more likely to be dead by the time they’re 18” than white boys.

“That’s, I think, shameful for the city,” he admitted.

“The challenge for us is, as we reach in to tackle those issues, that confrontation that comes from that reaching in, whether it’s stop and search on the streets or the sort of operations you seek.

“The danger is that’s landing in an environment with less trust.

“And that makes it even harder. But the people who win out of that [are] all of the criminals.”

The commissioner added: “I’m so determined to find a way to get past this because if policing in black communities can find a way to confront these issues, together we can give black boys growing up in London equal life chances to white boys, which is not what we’re seeing at the moment.

“And it’s not simply about policing, is it?”

Sir Mark said: “I think black boys are several times more likely to be excluded from school, for example, than white boys.

“And there are multiple issues layered on top of each other that feed into disproportionality.”

‘We’re stretched, but there’s hope and determination’

Sir Mark said the Met is a “stretched service” but people who call 999 can expect an officer to attend.

“If you are in the middle of a crisis and something awful is happening and you dial 999, officers will get there really quickly,” Sir Mark said.

“I don’t pretend we’re not a stretched service.

“We are smaller than I think we ought to be, but I don’t want to give a sort of message of a lack of hope or a lack of determination.”

“I’ve seen the mayor and the home secretary fighting hard for police resourcing,” he added.

“It’s not what I’d want it to be, but it’s better than it might be without their efforts.”

‘Close to broken’ justice system facing ‘awful’ delays

Sir Mark said the criminal justice system was “close to broken” and can be “frustrating” for police officers.

“The thing that is frustrating is that the system – and no system can be perfect – but when the system hasn’t managed to turn that person’s life around and get them on the straight and narrow, and it just becomes a revolving door,” he said.

“When that happens, of course that’s frustrating for officers.

“So the more successful prisons and probation can be in terms of getting people onto a law-abiding life from the path they’re on, the better.

“But that is a real challenge. I mean, we’re talking just after Sir Brian Leveson put his report out about the close-to-broken criminal justice system.

“And it’s absolutely vital that those repairs and reforms that he’s talking about happen really quickly, because the system is now so stressed.”

Giving an example, the police commissioner went on: “We’ve got Snaresbrook [Crown Court] in London – it’s now got more than 100 cases listed for 2029.”

Sir Mark asked Trevor Phillips to imagine he had been the victim of a crime, saying: “We’ve caught the person, we’ve charged him, ‘great news, Mr Phillips, we’ve got him charged, they’re going to court’.

“And then a few weeks later, I see the trial’s listed for 2029. That doesn’t feel great, does it?”

Asked about the fact that suspects could still be on the streets for years before going to trial, Sir Mark conceded it’s “pretty awful”.

He added: “If it’s someone on bail, who might have stolen your phone or whatever, and they’re going in for a criminal court trial, that could be four years away. And that’s pretty unacceptable, isn’t it?”

Challenge to reform the Met

The Met chief’s comments come two years after an official report found the force is institutionally racist, misogynistic and homophobic.

Baroness Casey was commissioned in 2021 to look into the Met Police after serving police officer Wayne Couzens abducted, raped and murdered Sarah Everard.

She pinned the primary blame for the Met’s culture on its past leadership and found stop and search and the use of force against black people was excessive.

At the time, Sir Mark, who had been commissioner for six months when the report was published, said he would not use the labels of institutionally racist, institutionally misogynistic and institutionally homophobic, which Baroness Casey insisted the Met deserved.

However, London Mayor Sadiq Khan, who helped hire Sir Mark – and could fire him – made it clear the commissioner agreed with Baroness Casey’s verdict.

A few months after the report, Sir Mark launched a two-year £366m plan to overhaul the Met, including increased emphasis on neighbourhood policing to rebuild public trust and plans to recruit 500 more community support officers and an extra 565 people to work with teams investigating domestic violence, sexual offences and child sexual abuse and exploitation.

A leading NHS hospital has warned measles is on the rise among children in the UK, after treating 17 cases since June.

Alder Hey Children’s Hospital in Liverpool said it is “concerned” about the increasing number of children and young people who are contracting the highly contagious virus.

It said the cases it has treated since June were for effects and complications of the disease, which, in rare cases, can be fatal if left untreated.

“We are concerned about the increasing number of children and young people who are contracting measles. Measles is a highly contagious viral illness which can cause children to be seriously unwell, requiring hospital treatment, and in rare cases, death,” the hospital said in a statement to Sky News.

In a separate open letter to parents and carers in Merseyside earlier this month, Alder Hey, along with the UK Health and Security Agency (UKHSA) and directors of Public Health for Liverpool, Sefton and Knowsley, warned the increase in measles in the region could be down to fewer people getting vaccinated.

The letter read: “We are seeing more cases of measles in our children and young people because fewer people are having the MMR vaccine, which protects against measles and two other viruses called mumps and rubella.

“Children in hospital, who are very poorly for another reason, are at higher risk of catching the virus.”

It comes after a Royal College of Paediatrics and Child Health (RCPCH) report released earlier this month determined that uptake of vaccines in the UK has stalled over the last decade and is, in many cases, declining.

It said none of the routine childhood vaccinations have met the 95% coverage target since 2021, putting youngsters at risk of measles, meningitis and whooping cough.

The MMR vaccine has been available through the NHS for years. Two doses gives lifelong protection against measles, mumps and rubella.

According to the latest NHS data, Liverpool was one of the cities outside London with the lowest uptake of the MMR vaccination in 2023-2024.

By the time children were five years old, 86.5% had been give one dose, decreasing to 73.4% for a second dose.

The RCPCH report put the nationwide decline down to fears over vaccinations, as well as families having trouble booking appointments and a lack of continuous care in the NHS, with many seeing a different GP on each visit.

In the US, measles cases are at their highest in more than three decades.

Cases reached 1,288 on Wednesday this week, according to the US Centres for Disease Control and Prevention, with 14 states battling active outbreaks.

The largest outbreak started five months ago in communities in West Texas, where vaccination uptake is low. Since then, three people have died – including two children in Texas and an adult in New Mexico – with dozens more in hospital.
