The allegations are contained in a letter written to the CIA by House Coronavirus Subcommittee Chairman Brad Wenstrup (R-Ohio) and House Intelligence Committee Chairman Mike Turner (R-Ohio).

The whistleblower is described as a "multi-decade, senior-level, current Agency officer. He told Congress that the CIA assigned seven officers to a "COVID Discovery team," which consisted of "multi-disciplinary and experienced officers with significant scientific expertise."

"According to the whistleblower, at the end of its review, six of the seven members of the Team believed that intelligence and science were sufficient to make a low confidence assessment that COVID-19 originated from a laboratory in Wuhan, China," Wenstrup and Turner wrote.

"The seventh member of the Team, who also happened to be the most senior, was the one officer to believe COVID-19 originated through zoonosis."
