Does Biden Hold Any Responsibility for COVID-19?

With Biden’s ties to China coming to light, I can’t help but wonder what he may have known prior to the COVID-19 outbreak. He is obviously close to the CCP & the are pushing for him to win the election. Did the CCP release this virus to hurt Trumps re-election chances? Did Biden have any knowledge about this if so? His potential foreign relationships are bringing up so many questions.
