President Trump is giving the World Health Organization 30 days to commit to substantial changes in how it operates — or he will make his hold on U.S. funding permanent.

"The World Health Organization has repeatedly made claims about the coronavirus that were either grossly inaccurate or misleading," Trump wrote in the four-page letter to WHO Director-General Tedros Adhanom Ghebreyesus.
