And the president delivered a blunt warning from the White House: “Nobody’s going to be able to do a damn thing about it.”
The International Olympic Committee cannot have been surprised.
Trump had been riffing off this intentionally inflammatory rhetoric throughout the campaign, complaining transgender women competing in women’s events are cheating and endangering rivals.
This East Room ceremony – surrounded by female athletes – turned the policy pledge into reality through an executive order.
“This is one of the big reasons that we all won,” he said, between meandering into how he could have built a bigger ballroom for the occasion.

For now this US order only directly impacts education institutions receiving federal funding.

Trans athlete ban ‘is common sense’
But Trump is putting pressure on the IOC, which leaves eligibility rules to each sport to determine.
“In Los Angeles in 2028 my administration will not stand by and watch men beat and batter female athletes,” Trump said.
“We’re just not going to let it happen and it’s going to end and it’s ending right now.”
How many athletes would this policy have impacted at the Paris 2024 Olympics?
Technically, none.

There was a trans man fighting who was female at birth. And two non-binary athletes competing in their assigned sex at birth categories. They are not in Trump’s sights.
Secretary of State Marco Rubio has been told to “make clear to the International Olympic Committee… that America categorically rejects transgender lunacy”.
Trump added: “We want them to change everything to do with the Olympics and this absolutely ridiculous subject.”
Maybe this was the moment the IOC started regretting awarding 2028 to Los Angeles. Trump boasts about winning that Olympic vote during his first term having never anticipated being in power for the Games themselves.
While protecting women’s sport is the mission, the inclusive, unifying and celebratory messaging promoted by the Olympics is being undercut.
The Department of Homeland Security was ordered “to deny any and all visa applications made by men attempting to fraudulently enter the United States while identifying themselves as women athletes”.
There has not been a widespread distortion of competition by transgender women with physical advantages but it is a growing challenge confronting sports leaders.
Widely shared clips of some American college sports events being won by trans women have fed into wider culture war with Trump siding against “woke lunacy”.
The messaging resonated with voters believing the fairness of competitions is being distorted by trans athletes by having skeletal advantages from puberty after being male at birth.
Those physical advantages can pose a safety threat – particularly in combat sports.
Activists advocating for LGBT+ rights in sport decried the targeting of another marginalised community by the Trump administration.
Athlete Ally said in a statement: “Our hearts break for the trans youth who will no longer be able to know the joy of playing sports as their full and authentic selves.”
But many across the United States are sure to endorse Trump delivering on his “common sense” agenda.
“You’ve been waiting a long time for this,” he said, before signing the “No Men in Women’s Sports” executive order into law.
Donald Trump has responded after Elon Musk said some of his recent social media posts about the US president “went too far”.
The Tesla and SpaceX boss shared a series of posts on his X social media platform last week, including one which described Mr Trump’s sweeping tax and spending bill as a “disgusting abomination”.
Posting on X this morning, Mr Musk said: “I regret some of my posts about President @realDonaldTrump last week. They went too far.”
In response, the president is quoted as telling the New York Post: “I thought it was very nice that he did that.”
The publication said it spoke to Mr Trump in a brief phone conversation.

Musk and Trump’s bust-up
The White House dismissed Mr Musk’s Epstein claims at the time, with press secretary Karoline Leavitt saying: “This is an unfortunate episode from Elon, who is unhappy with the One Big Beautiful Bill [a Republican tax and spending bill] because it does not include the policies he wanted.
“The president is focused on passing this historic piece of legislation and making our country great again.”
Mr Musk did not specify which posts he regretted.

A curfew has come into force in Los Angeles as officials attempt to “stop the vandalism and stop the looting”.
Mayor Karen Bass said the restrictions will be in force in downtown areas of the city from 8pm to 6am local time (4am to 2pm UK time) – and will likely be repeated in the coming days.
She confirmed that a local emergency had been declared as “we reached a tipping point”, with 23 businesses looted on Monday night.
Ms Bass said “graffiti is everywhere”, with “significant damage” to properties as a result of the protests.

Jim McDonnell, the chief of the Los Angeles Police Department, described the curfew as a “necessary measure to protect lives” as “unlawful and dangerous behaviour” had been escalating in the last few days.
On Tuesday alone, 197 arrests were made by the force, and he warned anyone violating the curfew without a valid reason would be detained.
Residents, people who are homeless, those travelling to and from work, credited media as well as public safety and emergency personnel, will be exempt from the curfew.

The protests are in response to raids carried out by the US Immigration and Customs Enforcement agency (ICE).
US President Donald Trump has activated 4,000 National Guard troops – the federal reserve force – to protect ICE officers carrying out raids as well as federal buildings in LA, despite objections by California Governor Gavin Newsom, who called the deployments unnecessary, illegal and politically motivated.
Mr Trump also sent 700 marines, who are expected to start operating in the LA area on Wednesday, according to the US Northern Command.

State officials said Mr Trump’s response was an extreme overreaction to mostly peaceful demonstrations, with California senators Adam Schiff and Alex Padilla saying the domestic mobilisation of active-duty military personnel should only happen “during the most extreme circumstances, and these are not them”.
Mr Trump defended his decision in a speech to soldiers at the Army base in Fort Bragg, North Carolina, saying his administration would “liberate Los Angeles”.

Trump: ‘We will liberate Los Angeles’
“Generations of Army heroes did not shed their blood on distant shores only to watch our country be destroyed by invasion and third-world lawlessness,” Mr Trump said.
“What you’re witnessing in California is a full-blown assault on peace, on public order and on national sovereignty, carried out by rioters bearing foreign flags.”

Gavin Newsom launched a blistering response in an address on Tuesday evening, saying the deployment of the National Guard without consulting Californian officials was a “brazen abuse of power by a sitting president”.
He said it “enflamed a combustible situation, putting our people, our officers and even our National Guard at risk”.
“That’s when the downward spiral began. He doubled down on his dangerous National Guard deployment by fanning the flames even harder – and the president, he did it on purpose,” Mr Newsom said.
Newsom takes the fight to Trump
California Governor Gavin Newsom’s televised address to the nation felt presidential as he took the fight to the man in the Oval Office, with a series of scorching putdowns.
He made a compelling case that Donald Trump’s extraordinary decision to send troops to LA against his wishes had put the country on the brink of authoritarianism.
He spoke the day after the Pentagon announced 700 marines were being deployed to join 4,000 National Guard troops ordered to the streets of LA by Trump.
But there has been no evidence so far that local law enforcement is being overwhelmed by the size or might of this resistance movement.
The head-to-head between Trump and Newsom is a compelling one.
The governor is known to harbour presidential ambitions for 2028 and is something of a MAGA bogeyman.
Newsom presides over a blue state, the biggest in the country, and is growing his brand with a podcast and – now – Trump has effectively put him in the national spotlight by bringing this political battle to his door.

The governor accused Mr Trump of choosing escalation and “theatrics over public safety”, as the situation was “winding down” before the president deployed the troops.
Mr Newsom added: “When Donald Trump sought blanket authority to commandeer the National Guard, he made that order apply to every state in this nation.
“This is about all of us, this is about you. California may be first, but it clearly won’t end here; other states are next. Democracy is next. Democracy is under assault before our eyes.”

Homeland Security said on Monday that ICE had arrested 2,000 immigration offenders per day recently, which significantly exceeds the 311 daily average in the fiscal year 2024 under former president Joe Biden.
The protests over the immigration raids have started to spread across the US, with demonstrations in cities like Seattle, Austin, Chicago and Washington, DC.
While chaos in Los Angeles continues, with a curfew in place in the city to prevent further unrest, Donald Trump spent the day hunkered down in a bunker with helicopters soaring above and drones buzzing by at a celebration of the US army’s birthday.
US correspondents Mark Stone in Washington DC and Martha Kelner in LA discuss the parallels between the president’s display of military celebration, and sending troops in to restore law and order against protesters.
Plus, as US and Chinese negotiators meet in London to try and resolve the ongoing trade war between the two nations, Mark and Martha ask what’s at stake.
