Generic drug manufacturers must move production to the US or face a 100% import duty from August 2028, President Donald Trump said, threatening the supply of low-cost medicines that millions of Americans rely on. The move is aimed at "reshoring" generic pharmaceutical production in the US, and companies that don't build plants onshore will face levies that would then double, to 200%, in August 2029, Trump said in a social media post. Naomi Kresge, Bloomberg Health Reporter, joins to discuss.
