President Joe Biden has by executive order reversed the decision by the Trump administration to withdraw from the World Health Organization. This is part of steps being taken by the President to reengage with the (WHO), reversing a decision the Trump administration made in July, several months into the coronavirus pandemic.

White House press secretary Jen Psaki said Biden signed an executive order Wednesday to stop the U.S.’s departure from the organization, fulfilling a promise he made during the campaign.

Formal withdrawal requires a year’s notice, so former President Trump’s decision would not have taken effect until July 6.

As part of the move, Anthony Fauci, the nation’s top infectious diseases expert, will head the U.S. delegation to WHO and participate in the organization’s executive board meeting Thursday.
