Any source of the virus is a possibility. There has been no scientifically proven and accepted finding of the source. The fact is that the virus spread from Wuhan, the home to China's Virology Laboratory. Mere coincidence? Definitely worth digging into.
The Chinese Government will prevent a full and independent investigation of the source of the virus. So, we will never know.
FWIW, have no idea why any anti-Trump forces feel the need to exclude the possibility that COVID 19 was created and escaped from a Chinese lab (other than anything that comes from Trump must be wrong). The previous administration's bungled response and prolonged failure to develop a coherent national strategy to deal with Covid 19 killed Americans and destroyed businesses. Whether the virus was manmade by the Chinese Government or from a natural source, has no bearing on the failures of the Trump administration. Those trying too hard to exclude consideration of all possible sources just give more cover for the whacked-out conspiracy theorists.
