US President Donald Trump has attracted condemnation from health experts, after he sought to claim there was a link between the widely used painkiller Tylenol and autism.
Accompanied by his Health Secretary Robert F Kennedy Jr, Trump said doctors would soon be advised not to recommend the drug - called paracetamol in some other countries, including the UK - to pregnant women.
The claims have been attacked by medical experts. The American College of Obstetricians and Gynaecologists said the announcement was "unsettling" and not based on "reliable data", while the UK's National Autism Society called Trump's statement "dangerous, it's anti-science and it's irresponsible".
BBC Verify has looked at some of the allegations Trump and Kennedy made during their news conference at the White House.
During the event, Trump listed a number of statistics which he said showed autism diagnoses in the US have risen rapidly over the past two decades.
