Legally, can President Trump withdraw the US from membership of the WHO?

– The WHO Constitution is a treaty.
– Membership of WHO requires signing the WHO Constitution & completing state domestic ratification processes (art 4).
– US has ratified the treaty.

*From WHO side*
WHO Constitution does not set out an express withdrawal process. This is not unusual and it is generally accepted that States are free to withdraw from international treaties & institutions (principle of state sovereignty, enshrined in Vienna Convention)

*US side*
Legally it& #39;s murky if the President can withdraw. While Exec has power to sign treaties, ratification follows advice & consent of Senate.
– Some argue Exec thus retains power to exit treaties
– Others argue it requires Congress consent:

PS The question of legality is only one angle (inc what it means for other int laws for #covid19: eg can be a party to the IHR but not a WHO Member).
Politics likely matters more (& extent would impact any legal review). Also, it& #39;s not clear what was intended by "terminating".
An important addendum:

Precisely because the WHO Constitution is silent on withdrawing, the US Congress included a provision that the US must pay any outstanding dues before withdrawing.

For the law wonks: here& #39;s the text of the Joint Resolution of US Congress (1948) [62 Stat 441] with the US& #39;s Understanding regarding withdrawal on ratification of WHO Constitution.
