On his first day in office, Donald Trump froze foreign aid funding, ordering an immediate review into USAID, the government agency which was running programmes in around 120 countries. The review was swift and the cuts severe. President Trump’s team concluded that tens of billions of dollars were being spent in ways which “did not serve” or “harmed" US interests. We hear from USAID employees who describe the shock of suddenly losing their own jobs, and the grim anticipation of the impact the cuts will have on people around the world. We also hear from people running treatment centres around the world, and about the impact on HIV provision in Africa.
