Have you forgotten about ‘due process’? Just because someone says something doesn’t make it true. To spread an unproven allegation as if it were proven fact is highly irresponsible!
(I’m not just trying to defend Biden here. I even defended Brett Kavanaugh, who I didn’t like, on the same grounds. The slippery slope towards giving consideration to every unproven allegation about everyone is a dangerous development, a grave threat to liberty and justice!)
