A study released by the House Republicans on Monday, Aug. 2, concludes that the coronavirus that caused the COVID-19 pandemic leaked from the Wuhan lab in China.

The Republicans on the House Foreign Affairs Committee, led by Rep. Michael McCaul (R-Texas), released their report of the investigation into the origins of COVID-19, which points to problems with the Chinese research facility in question.

The report cited “ample evidence” that Wuhan Institute of Virology (WIV) scientists—aided by U.S. experts and Chinese and U.S. government funds—worked to modify coronaviruses to infect humans. Such manipulation could be hidden, according to Reuters.

“As we continue to investigate the origins of the COVID-19 pandemic, I believe it’s time to completely dismiss the wet market as the source of the outbreak,” Rep. McCaul said, defying some experts who suspect the pandemic was caused by an animal virus likely transmitted to humans at a seafood market near the WIV.

“Instead, as this report lays out, a preponderance of the evidence proves that all roads lead to the WIV. We know gain-of-function research was happening at the WIV and we know it was being done in unsafe conditions. We also now know the head of the Chinese CDC and the director of the WIV’s BSL-4 lab publicly expressed concerns about safety at PRC labs in the summer of 2019,” he said.

The communist regime has repeatedly denied that coronavirus leaked from the Wuhan lab, but more evidence surfaced backing claims previously called a conspiracy theory.

McCaul alleged that the Chinese Communist Party officials tried to cover up the coronavirus origin and its outbreak.

“It is our belief the virus leaked sometime in late August or early September 2019,” he said. “When they realized what happened, Chinese Communist Party officials and scientists at the WIV began frantically covering up the leak, including taking their virus database offline in the middle of the night and requesting more than $1 million for additional security. But their coverup was too late – the virus was already spreading throughout the megacity of Wuhan.”

“Within a month, satellite images show a significant uptick in the number of people at hospitals around the WIV with symptoms similar to COVID-19. At the same time, athletes at the Military World Games became sick with symptoms similar to COVID-19. Some of them carried the virus back to their home countries – creating one of the earliest super spreader events in the world, and explaining how countries who participated in the games had reported cases as early as November 2019,” he continued.

McCaul called for Congress to sanction the Wuhan scientists and the Chinese Communist Party officials involved in the alleged cover-up.

“This was the greatest coverup of all time and has caused the deaths of more than four million people around [the] world, and people must be held responsible,” the top Republican on the House Foreign Affairs Committee said.
