U.S. National Security Adviser Matthew Pottinger is reiterating the theory that COVID-19 leaked from a Chinese government-run lab in Wuhan.

Pottinger made that claim in a recent Zoom meeting with British officials, according to a New York Post report.

Pottinger, a famous critic of Beijing, said that there is a growing evidence that the lab is likely the most credible source of the pandemic.

The security official stated the theory as the European Union made a new investment deal with China last week over protests from Pottinger.

The incoming Biden administration has also shown hesitance about the said investment. Pottinger is one of the first U.S. officials to raise alarms about the origins of the virus last year

He has reportedly suspected since the early days of the outbreak that the coronavirus originated in a Chinese lab.

Pottinger then ordered U.S. intelligence agencies to search for evidence to support its unsubstantiated theory that it originated in a government-run laboratory, as reported by The New York Times.

Was COVID-19 man-made?

Meanwhile, a Chinese virologist said that she did some of the earliest research on COVID-19.

The said virologist then claimed that COVID-19 was man-made and that the Chinese government covered up its dangers.

However, Western medical experts have refuted the theory. The World Health Organization has been investigating the source of the virus since the first case was reported last year.

Patient Zero has not been found. Pottinger went on to accuse that the WHO investigation is a ruse in the recent call with British officials.

The Trump administration has blamed China for the pandemic ever since it started. In part, this is to deflect criticism about the administration's alleged downplaying of the crisis in the country.

Anthony Ruggiero, a National Security official, said in one videoconference that the CIA was unable to get any theory of the virus' origin.

Former Tony Party leader official said that Beijing's hesitance to allow journalist visit the lab has increased suspicions that it was indeed the base ground of the virus.

"The truth is there are people who have been in those labs who maintain that this is the case," Iain Duncan Smith was quoted on a Daily Mail report.

Smith said that they do not know what they have been doing in that laboratory. Critics also fear that the probe will be a whitewash with China's influence on the WHO.

Pottinger said that MPs around the world have a moral role to play in exposing the WHO investigating the COVID-19 case as a Potemkin case.

Pottinger was referring to the fake villages created in the Crimea in the 18th Century for the purpose of convincing visiting Russian Empress Catherine the Great that the region was in good condition.

Meanwhile, the U.S. Security official went on to say that every establishment figures in Beijing have openly dismissed the wet market story.
