The Wall Street Journal is reporting the Energy Department has revised its assessment of the origins of COVID-19, saying the spread of the virus was likely an unintentional leak from a Chinese lab. The agency, however, has only “low confidence” in the theory, according to reports. The FBI has previously said it also believes with “moderate confidence” COVID-19 is the result of a lab leak. The latest news widens the split in the U.S. intelligence community as the National Intelligence Council and four other agencies have concluded COVID-19 was naturally transmitted by an infected animal.
