On April 15, 2020, President Trump stated the US will freeze World Health Organisation (WHO) funding for 60-90 days, pending a formal investigation into the global health agency’s response to the global COVID-19 pandemic. Trump repeatedly signaled the move after accusing the WHO of having a bias in favor of China.
On July 7, 2020 President Trump took the first formal step toward withdrawing the U.S. from the WHO by submitting a “notice of withdrawal” to the United Nations secretary-general, making the parting effective July 6, 2021. Withdrawing from the organization requires a one-year notice before becoming final.
On September 2, 2020, Trump cancels $62M of US funding for World Health Organization, “which was slated to receive $120 million in the 2020 fiscal year from the United States.” In 2019 the US contributed $450 million, accounting for 15% of it’s total budget.
In January 2021, Biden stopped this move and rejoined the US to the WHO.
