WHO’s constitution, drafted in New York, doesn’t have a clear exit method for member states. A joint resolution by Congress in 1948 outlined that the U.S. can withdraw with one year's notice. This is contingent, however, on ensuring that its financial obligations to WHO “shall be met in full for the organization’s current fiscal year.”

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.

This isn't the first fight Trump has picked with the WHO. His administration began the removal process in July 2020 during the first year of the COVID-19 pandemic. Former President Joe Biden halted the exit in one of his first actions when he started his presidential term in 2021.
