WASHINGTON – The Trump administration has officially begun to withdraw the United States from the World Health Organization, even as the COVID-19 pandemic continues to grip the globe and infections spike in many states across the U.S.

Congress received formal notification of the decision on Tuesday, more than a month after President Donald Trump announced his intention to end the U.S. relationship with the WHO and blasted the multilateral institution as a tool of China. The White House said the withdrawal would take effect on July 6, 2021.

Democrats said the decision was irresponsible and ill-considered, noting it comes as the pandemic is raging and international cooperation is vital to confront the crisis.

“This won’t protect American lives or interests – it leaves Americans sick & America alone,” Sen. Bob Menendez, the top Democrat on the Senate Foreign Affairs Committee, tweeted after receiving the White House’s notification. “To call Trump’s response to COVID chaotic & incoherent doesn’t do it justice.”

Joe Biden, the presumptive Democratic presidential nominee, said he would rejoin the WHO immediately if he wins.

“Americans are safer when America is engaged in strengthening global health. On my first day as President, I will rejoin the @WHO and restore our leadership on the world stage,” the former vice president tweeted.

Tarik Jasarevic, a spokesman for the WHO, said the organization had received reports of the United States’ formal notification. “We have no further information on this at this stage,” he said.

The formal withdrawal comes as the United States nears 3 million reported coronavirus cases and more than 130,000 deaths, according to Johns Hopkins University data. Globally, there have been 11.6 million cases and almost 540,000 deaths.

Trump and his advisers have blasted the WHO for failing to press China to be more transparent about the scope and severity of the COVID-19 outbreak, which began in Wuhan, China.
