The bipartisan delegation said more conversations were necessary to avoid accidental “miscalculations and misunderstandings” that could lead to conflict.
Major medical groups say it is safe for pregnant women to take Tylenol, also known as Paracetamol
Trump officials are expected to link the use of pain reliever Tylenol in pregnant women to autism, according to US media reports.
At an Oval Office event on Monday, the US president will reportedly advise pregnant women in the US to only take Tylenol, known as paracetamol elsewhere, to relieve high fevers.
At the Charlie Kirk memorial service on Sunday, Trump said he had an "amazing" announcement coming on autism, saying it was "out of control" but they might now have a reason why.
Some studies have shown a link between pregnant women taking Tylenol and autism, but these findings are inconsistent and do not prove the drug causes autism.
Tylenol is a popular brand of pain relief medication sold in the United States, Canada and some other countries. Its active ingredient is acetaminophen, which is called paracetamol outside North America.
Tylenol maker Kenvue has defended the use of the drug in pregnant women.
In a statement to the BBC, it said: "We believe independent, sound science clearly shows that taking acetaminophen does not cause autism. We strongly disagree with any suggestion otherwise and are deeply concerned with the health risk this poses for expecting mothers."
Acetaminophen is the safest pain reliever option for pregnant women, it added, and without it, women face a dangerous choice between suffering through conditions like fever or use riskier alternatives.
The BBC has contacted the Department of Health and Human Services (HHS) for comment.
In April, the leader of HHS, Robert F Kennedy Jr, pledged "a massive testing and research effort" to determine the cause of autism in five months.
But experts have cautioned that finding the causes of autism - a complex syndrome that has been researched for decades - would not be simple.
The widely held view of researchers is that there is no single cause of autism, which is thought to be the result of a complex mix of genetic and environmental factors.
The American College of Obstetrics and Gynecology said doctors across the country have consistently identified Tylenol as one of the only safe pain relievers for pregnant women.
"[S]tudies that have been conducted in the past, show no clear evidence that proves a direct relationship between the prudent use of acetaminophen during any trimester and fetal developmental issues," the group has said.
The drug is recommended by other major medical groups as well as other governments around the world.
In August, a review of research led by the dean of Harvard University's Chan School of Public Health found that children may be more likely to develop autism and other neurodevelopmental disorders when exposed to Tylenol during pregnancy.
The researchers argued some steps should be taken to limit use of the drug, but said the pain reliever was still important for treating maternal fever and pain, which can also have negative effects for children.
"There is no robust evidence or convincing studies to suggest there is any causal relationship," said Monique Botha, a professor in social and developmental psychology at Durham University.
Dr Botha added that pain relief for pregnant women was "woefully lacking", with Tylenol being one of the only safe options for the population.
Autism diagnoses have increased sharply since 2000, and by 2020 the rate among 8-year-olds reached 2.77%, according to the US Centers for Disease Control and Prevention (CDC).
Scientists attribute at least part of the rise to increased awareness of autism and an expanding definition of the disorder. Researchers have also been investigating environmental factors.
In the past, Kennedy has offered debunked theories about the rising rates of autism, blaming vaccines despite a lack of evidence.
Watch: Alaa Abdel Fattah reunited with family following release from prison
British-Egyptian activist Alaa Abdel Fattah has been freed and reunited with his family after almost six years of imprisonment in Egypt.
One of the country's most prominent political prisoners, he was pardoned by President Abdul Fattah al-Sisi on Monday, reportedly after a request from the National Council for Human Rights.
Video of the blogger and pro-democracy activist, 43, at home after his release shows him grinning widely and jumping up and down as he celebrates with his sister and mother.
Laila Soueif, who went on extensive hunger strike during her son's imprisonment, said on his release: "Despite our great joy, the biggest joy is when there are no [political] prisoners."
Abdel Fattah was released from Wadi al-Natrun prison late on Monday and celebrated reuniting with his family at his mother's apartment in Giza.
"I cannot yet comprehend that this is real," his sister Sanaa Seif said.
The activist was arrested in 2019 during a crackdown on dissent and sentenced to five years in prison after being convicted of "spreading false news" for sharing a post about a prisoner dying of torture.
Two weeks ago, Sisi ordered the authorities to study the NCHR's petitions for the release of Abdel Fattah and six others, which the institution said it had submitted "in light of the humanitarian and health conditions experienced by [their] families".
His family said he should have been released in September 2024 but the two years he spent in pre-trial detention were not counted as time served by Egyptian authorities.
When Abdel Fattah was not released at the end of his five-year sentence, his mother Laila Soueif started an extensive hunger strike to call for his release.
She was hospitalised at St Thomas' Hospital in London and came close to death twice during the 287-day strike, which ended on 14 July after then-Foreign Secretary David Lammy told Parliament he "expected [Abdel Fattah] to be released" on 25 June.
Prime Minister Sir Keir Starmer had previously said he would secure Abdel Fattah's freedom and there has been widespread cross-parliamentary support for his release.
It is unclear if Abdel Fattah will be able to travel to the UK to be with his son, though his sister said on his release that his release would "feel more real" when "his son arrives here from travelling".
The activist first rose to prominence during the 2011 uprising in Egypt that forced long-time President Hosni Mubarak to resign.
He has spent most of his time in prison since 2014, the year after Sisi led the military's overthrow of Egypt's first democratically elected president, Muslim Brotherhood leader Mohammed Morsi.
Sisi has overseen what human rights groups say is an unprecedented crackdown on dissent that has led to the detention of tens of thousands of people.
Although Abdel Fattah acquired British citizenship in 2021, Egypt has never allowed him a consular visit by British diplomats.
In May, the UN Working Group on Arbitrary Detention - a panel of independent human rights experts – found that Abdel Fattah had been arbitrarily arrested for exercising his right to freedom of expression, had not been given a fair trial and had remained in detention for his political opinions.
According to the panel, the Egyptian government said he had been afforded "all fair trial rights" and that his sentence would be completed in January 2027.
"At what point did we become North Korea?" That was the question Nigel Farage posed when asked by a US congressional committee about limitations on freedom of speech in the UK.
He was condemning the "awful authoritarian situation we have sunk into", which he claimed had led to various arrests including that of Father Ted co-creator Graham Linehan over his views on challenging "a trans-identified male" in "a female-only space".
When I heard the question, I confess I thought that the leader of Reform UK had gone over the top.
Farage was comparing his country - my country - with a brutal dictatorship that murders, imprisons and tortures opponents.
And he was doing it in front of an influential audience of American lawmakers.

When I interviewed his deputy, Richard Tice on Radio 4's Today, I asked him whether he really believed that UK Prime Minister Sir Keir Starmer was the same as North Korean leader Kim Jong Un.
Three times I asked the question. Three times Tice swerved it, suggesting Farage was simply using "an analogy".
But Farage is not alone in questioning how far restrictions to freedom of speech have gone in the UK.
Tensions around the limits of free speech are nothing new and since the advent of social media in the mid-2000s, the arguments have been simmering.
Now, though, they're reaching a boiling point.

Farage lambasted the 'awful authoritarian situation we have sunk into'
During his recent visit, US Vice-President JD Vance said he did not want the UK to go down a "very dark path" of losing free speech.
The US business magazine Forbes carried an editorial this month that took this argument further still.
In it, editor-in-chief Steve Forbes condemned the UK's "plunge into the kind of speech censorship usually associated with tin pot Third World dictatorships".
He argues that, in stark contrast to the United States - where free speech is protected by the first amendment to the constitution, "the UK has, with increasing vigour, been curbing what one is allowed to say, all in the name of fighting racism, sexism, Islamophobia, transgenderism, climate-change denial and whatever else the woke extremists conjure up".
So, how exactly did we get to the point where the UK is being compared to a dictatorship and, given how inflamed the conversation has become, what - if anything - would it take to turn down the heat?
Big tech dialled up the debate
The case of Lucy Connolly has become a cause celebre to some in the UK and beyond.
The former childminder from Northampton, who is married to a Conservative councillor, had posted an abhorrent message on X, calling for people to "set fire" to hotels housing asylum seekers following the murder of three young girls at a dance class in Southport in July 2024.
It was viewed hundreds of thousands of times at a time when the threat of violence was very real.

Lucy Connolly was jailed for 31 months after calling for hotels housing asylum seekers to be set on fire
Connolly had pleaded guilty to inciting racial hatred by publishing and distributing "threatening or abusive" written material on X. And yet she was given the red carpet treatment at the Reform party conference, as "Britain's favourite political prisoner".
The length of her prison sentence - 31 months although she only served 40% before she was released - was questioned by many, including people who were appalled by what she had written.
It is just one case that highlights how much social media has changed the shape of the debate around free speech and made heroes and villains of ordinary people.
And I use the word "ordinary" deliberately because views similar to Connolly's will have been expressed up and down the land by others who might well have said, as she now does, "I was an idiot".
But while it's unlikely that any action would have been taken had she said what she did in a coffee shop or a bar, the fact she posted it on social media changed things.

Facebook founder Mark Zuckerberg has changed the rules for Facebook and Instagram
What's more, big tech firms have changed their approach in recent years.
After Musk bought Twitter, which he re-named X, he changed content moderation, which he regards as "a propaganda word for censorship" - and he talks a lot about people spreading "the woke mind virus".
Facebook founder Mark Zuckerberg has also changed the rules governing Meta and Instagram.
In the case of Connolly, her post was "accelerated by the algorithm" and spread far more widely, according to Lilian Edwards, an emeritus professor at Newcastle University.
Dilemma around policing speech
The arrest of Graham Linehan at Heathrow, too, raised further questions around policing freedom of speech - and put the way issues are handled under renewed scrutiny.
Commissioner of the Metropolitan Police Sir Mark Rowley has voiced his own concerns. "It's a nonsense to pretend that with all of the (online) content out there that enforcement is the answer to that," he has said.
What these cases both illustrate is the lack of consensus about what can and should be policed online in the UK, and by who.
And a lack of consensus too about how we can set apart the unpleasant, offensive, ugly and hateful things said online from those that are genuinely threatening or dangerous.

Sir Mark Rowley: 'It's a nonsense to pretend that with all of the content out there that enforcement is the answer'
In the UK, the Human Rights Act does give protection to free speech but as a "qualified right".
This means that "governments can restrict that right… provided that the response is proportionate - [or] 'necessary in a democratic society' is what people tend to say", according to Lorna Woods, professor of internet law at the University of Essex.
But some of the comments made at the protest in London earlier this month, billed by far-right, anti-Islam activist Tommy Robinson as a "free speech rally," demonstrate that, despite other controversies, that right isn't that qualified.
Like nailing jelly to the wall
"Violence is coming" and "you either fight back or die", the billionaire X owner Elon Musk told flag-waving protesters via video link.
Along with his call for the overthrow of the government, some might argue that his words at the rally were an incitement to violence.
But the UK's independent reviewer of terrorism legislation, the barrister Jonathan Hall KC, has said that Musk's words would not have broken the law.
"Politicians use martial language all the time, don't they?" he told BBC Radio 4's Today. "Metaphors such as fights and struggles are pretty normal. And he was talking about it contingently, wasn't he? He wasn't saying: 'Go out immediately.'"

Musk called moderation "a propaganda word for censorship"
Yet the fact both men were able to address a huge crowd in London is perhaps evidence that there is rather more leeway for free speech in this country than those likening the UK to a "tin pot dictatorship" suggest.
According to Essex University's Prof Lorna Woods, the lowest level of views that can be prosecuted in British criminal law are those deemed "grossly offensive or of an indecent, obscene or menacing character".
These are concepts that few people without a law degree could easily define, let alone agree upon.
It is the job of the police initially, but ultimately the courts, to try to nail that particular piece of jelly to the wall.

Former deputy PM Sir Nick Clegg says the the UK is "out of whack" with other countries on free speech
The UK is "out of whack" with other countries, according to Sir Nick Clegg, the former deputy prime minister who later became right-hand man to Zuckerberg. He believes the UK needs to "think long and hard" about "whether we've overdone it" on policing speech.
"Surely part of the definition of being in a free society is people say ghastly things, offensive things, awful things, ugly things, and we don't sweep them under the carpet," he has said.
Free speech versus 'me speech'
What the British public want is another story.
Earlier this month, in a survey by YouGov, 5,035 British adults were asked what was most important when it came to online behaviour: 28% said it was that people were able to express themselves freely but 61% prioritised keeping them safe from threats and abuse.
"People tend to prefer safety to free speech [online]," argues Anthony Wells, a director at YouGov.
What's more, there seems to be a generational divide.

In a new YouGov survey, 61% of Britons said keeping people safe online was more important than absolute free speech
In my conversations with young people in their 20s and 30s - the age of my own children - I often hear the view that far from being an ideal to be strived for, free speech is the cause of much of the anger, division and fear they live with every day.
In recent years a "cancel culture" has emerged in which those with "unacceptable" views can be hounded out of their jobs, no platformed as speakers or intimidated as students.
Even back in 2021, a YouGov poll of Britons found that a majority of those surveyed - some 57% - had sometimes stopped themselves from expressing political or social views because of the fear of being judged or negative responses.
For those who believe that free speech is under threat in the country, these figures can be used as evidence that decades of political correctness has had a chilling effect on people's ability to express their opinions.
"Our definitions of what constitutes hate speech, and I think a very broadened definition of what constitutes harm, is meaning that people feel like they are walking on eggshells and they're frightened - not just that they'll have the police around, but that they'll be cancelled if they say the wrong thing," the former Brexit Party MEP Baroness Claire Fox told the BBC's The World Tonight.
But dig deeper and this debate, like so much else, is also about politics and the deepening and, increasingly, angry and violent divisions in our society.
What can America teach us?
Even with its constitutional protection for free speech, plenty in the UK question what basis Americans have to lecture Britain on free speech, given the arguments they are having back at home.
The anger and division sparked by the assassination of the conservative firebrand Charlie Kirk in Utah this month ramped up the debate further on that side of the Atlantic over where the boundaries should lie between what is offensive, hateful and dangerous.

ABC has suspended talk-show host Jimmy Kimmel over comments about the killing of right-wing influencer Charlie Kirk
Trump's Attorney General Pam Bondi appalled many conservatives when she declared that, "There's free speech and then there's hate speech".
It seemed to take her into precisely the territory, which has caused so many problems here in the UK.
President Trump himself has threatened to sue the New York Times for $15bn (£11bn) over what he calls defamation and libel, adding to the long list of media outlets he has taken to the courts over stories - the newspaper has called it "intimidation tactics" - and he celebrated the sacking of the late-night TV host Jimmy Kimmel as "great news for America".
The US historian Tim Snyder, who is an outspoken public critic of the direction America is heading under Trump believes that free speech should be distinguished from what he calls "me speech".

"Me speech is a common practice among rich and influential Americans," writes Mr Snyder. "Practitioners of me speech use the phrase free speech quite a bit.
"But what they mean is free speech for themselves. They want a monopoly on it.
"They believe that they are right about everything, and so they should always have giant platforms, in real life or on social media.
"The people with whom they disagree, however, should be called out and intimidated in an organised way on social media, or subjected to algorithmic discrimination so that their voices are not heard."
As much about listening
This issue is one I've felt strongly about for as long as I can remember. My grandparents knew first hand what it was to be persecuted for who you were and what you thought or said. They were German Jews who fled the Nazis for what then was the relative security of China and later had to flee the Communists there.
As a child, I recall watching in reverential silence as each day, after lunch, my grandfather held a huge radio on his lap and turned the dial, skipping stations until he found the BBC World Service. There, he had learned, he would find news he could trust and speech which was free of political control.
So important was this to him that he had risked hiding with his wife and daughter (my mother) in a cupboard in their home in Shanghai to listen to it on a banned shortwave radio.
Nick says he finds it hard to accept comparisons between the UK and a dictatorship
That is why I find any comparison between the UK and a dictatorship a little hard to swallow.
What I learned as the grandchild of those who had fled not one but two murderous ideologies was that free speech was about listening as much as talking.
What mattered above all else is being able to hear both sides of an argument and learn the facts behind them - without having that information controlled by governments, rich and powerful media owners, or anyone else.

Staff at Jaguar Land Rover (JLR) will be out of work for at least another week as the business secretary prepares to meet suppliers of the car maker who are at risk of closure.
JLR's production lines ground to a halt in late August following a major cyber attack, and fears are growing that the company's suppliers could go bust without support.
Business Secretary Peter Kyle will visit JLR to meet firms in the supply chain for the beleaguered carmaker.
JLR said in a statement on Tuesday that it would not be resuming production until October 1 at the earliest, an extension from the previous date of September 24.
"Our focus remains on supporting our customers, suppliers, colleagues, and our retailers who remain open," the statement said.
"We fully recognise this is a difficult time for all connected with JLR and we thank everyone for their continued support and patience."
Industry minister Chris McDonald said he was visiting JLR alongside the business secretary to "host companies in the supply chain, to listen to workers and hear how we can support them and help get production back online."
He said in a statement: "We have two priorities, helping Jaguar Land Rover get back up and running as soon as possible and the long-term health of the supply chain.
"We are acutely aware of the difficulties the stoppage is causing for those suppliers and their staff, many of whom are already taking a financial hit through no fault of their own - and we will do everything we can to reassure them that the government is on their side."
Suppliers are anxious to be heard, according to Johnathan Dudley, the head of manufacturing for accounting and consulting firm Crowe UK. The firm is based in the West Midlands, which is where the Solihull and Wolverhampton plants are.
"Obviously, they're being very, very cautious because they don't want to create panic, and equally, they don't want to be seen to be criticizing people further up the chain," he said.
"It's not a blame game, but it is a cry for help, because there are businesses now seeing people not paying [staff]."
The halt in production had hit profits by about £120m already, and £1.7bn in lost revenue, according to David Bailey, Professor of Business Economics at the University of Birmingham.
