Trump had started the process of leaving the World Health Organization in his first term but was not able to complete it.

By Patrick Wingrove, Jennifer Rigby and Emma Farge NEW YORK/LONDON/GENEVA (Reuters) -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.

The World Health Organization said it "regrets" US President Donald Trump's decision to withdraw his country from the UN agency.

Donald Trump's decision will have an even greater impact on the WHO, as the US is the main funder of the UN organization. This situation is likely to complicate many health policies, including the fight against future pandemics.

World leaders congratulated President Donald Trump on his inauguration Monday, with many urging stronger alliances or continued cooperation between their countries and the United States, in carefully crafted social media posts and statements.

One of President Trump’s first executive orders removes the U.S. from the global health organization, which experts say is “cataclysmic.”

As expected, President Donald Trump hit the ground running on Monday, signing scores of executive orders on various topics ranging from immigration to social issues. Among the policies implemented by Trump on his first day back in the White House were orders to withdraw the United States from two key international institutions.

President Donald Trump announced Monday he is withdrawing the US from the World Health Organization, in a significant move that drew criticism from public health experts on his first day back in the White House.

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 World Health Organization ( WHO) has responded to President Donald Trump 's recent executive order withdrawing the U.S. from the organization, warning that this move may undermine its core mission.

Trump announced he was granting pardons, commutations, and case dismissals to nearly 1,600 defendants charged over the Jan. 6 Capitol riot.
