President Donald Trump's decision to exit the World Health Organization means the U.N. agency is losing its biggest funder. For the two-year budget ending in 2025, the U.S. is projected to be WHO’s largest single contributor by far.

Ooh, that’s a big one,” Donald Trump said Monday as he signed an executive order – one of dozens during his first hours as president – to withdraw the United States from the World Health Organization.

The United States will leave the World Health Organization, President Donald Trump said on Monday, saying the global health agency had mishandled the COVID-19 pandemic and other international health crises.

Public health experts say U.S. withdrawal from the W.H.O. would undermine the nation’s standing as a global health leader and make it harder to fight the next pandemic.

This afternoon, the Associated Press is reporting that United States officials have officially ordered all public health officers to cease working at the World Health Organization just days after President Donald Trump signed an executive order pulling the United States out of the World Health Organization.

The World Health Organization is shaped by its members: 194 countries that set health priorities and make agreements about how to share critical data, treatments, and vaccines during international emergencies.
