In 2015 Obama gave a grant to the same lab that made the virus in Wuhan. That same year Nancy Pelosi traveled to Wuhan to talk to someone in person. We don't know what she said or who she said it to, that's why she went in person. If she were to write a letter or email, there would be a record of what she said and who she said it to. Plus that letter or email would be goverment property. I think Obama sent Pelosi to Wuhan to make a deal with the CCP and that lab first. Then Obama gave the grant of $3.7million once they made the deal. They also had to wait to release the virus during an election year.
