House Intelligence Committee Republicans released a report on the coronavirus pandemic on Wednesday and pointed the finger directly at the Wuhan Institute of Virology, arguing there is “overwhelming circumstantial evidence” supporting the hypothesis COVID-19 originated in the lab.

Officials from both the Trump and Biden administrations have said the Chinese government worked for over a year to thwart an independent investigation into the origins of the virus. Both administrations cast doubt on the manner in which a joint study from China and the World Health Organization was conducted earlier this year. Though the WHO-China report said a jump from animals to humans was most likely, numerous Trump officials have pointed to an accidental escape from the Wuhan lab as a highly plausible, or the most likely, origin for the pandemic.
