Anthony Fauci told Congress the NIH 'has not ever and does not now fund gain-of-function research in the Wuhan Institute of Virology.'

Scientists at Wuhan created chimeric coronaviruses that reproduced far more quickly than originals in engineered mice. EcoHealth was recommended for criminal investigation and debarment.
