Gates noted that “the world needs WHO now more than ever.”

“Halting funding for the World Health Organization during a world health crisis is as dangerous as it sounds. Their work is slowing the spread of COVID-19 and if that work is stopped no other organization can replace them. The world needs @WHO now more than ever,” Gates said.

Trump announced Tuesday he is halting funding to the WHO while a review is conducted into its handling of the coronavirus pandemic.
