President Donald Trump announced Monday he is withdrawing the US from the World Health Organization, a significant move on his first day back in the White House cutting ties with the United Nations’ public health agency and drawing criticism from public health experts.

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.

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.

As he signed an executive order, President Donald Trump said that the World Health Organization had "ripped us off."

Trump initially removed the U.S. from the WHO in 2020, but Biden reversed his action before it went into effect.

How America's legacy of combating threats to global health security - including at home in the United States - is at risk.

The U.S. has traditionally been the most generous benefactor of the WHO. A Trump executive order to cut ties with the WHO could pose a threat to global public health.

The World Health Organization called on the US to reconsider a decision to leave the agency, suggesting the move could undermine global health security.

By withdrawing from the World Health Organization and overhauling aid, Trump's new executive orders endanger Americans and the globe, researchers warn. The move also cedes U.S. power to other nations.

Wednesday on the RealClearPolitics podcast, Carl Cannon offered this question about the limits of Trump's isolationist tendencies: "Is Donald Trump going to keep the U.S. in the United Nations?"

President Trump in his first four days of a second term, made headlines with actions that altered US policies. From cracking down on immigration to reshaping energy and foreign relations, these moves set the stage for a contentious term.
