President Donald Trump announced Monday he is withdrawing the US from the World Health Organization, a significant move on his first day back in the White House cutting ties with the United Nations’ public health agency and drawing criticism from public health experts.

In 2020, Trump was highly critical of the WHO for being too "China-centric" in its tackling of Covid-19, and the organisation has since become a "target" of US conservatives over its work on a global pandemic treaty that they view as a "threat to American sovereignty", said the The New York Times.
