WASHINGTON, June 19 (Reuters) – The United States has backed down on a threat to halt funding for the World Health Organization (WHO) over its handling of the coronavirus pandemic, after coming under pressure from world leaders, including the head of Germany’s government. “Germany is convinced that the WHO needs to be strengthened, not weakened,” German Chancellor Angela Merkel said on Friday, adding that she had discussed the issue with U.S. President Donald Trump. .
