Trump withdraws US from dozens of international organizations, White House says

On January 7, US president Donald Trump promised to withdraw the US from 35 international organizations and 31 UN agencies:

The Memorandum orders all Executive Departments and Agencies to cease participating in and funding 35 non-United Nations (UN) organizations and 31 UN entities that operate contrary to U.S. national interests, security, economic prosperity, or sovereignty.

Unverified: then the White House deleted the announcement from their website (personal note: I did receive 404 on it for a while).

Correction: announcement is still up or has reappeared. An archived copy is also available in case they change their mind.
