I remember when Biden campaigned on the promise of addressing COVID by following the science.
Instead he got rid of mask mandates and there is serious discussions about banning masking in US states, biobot is no longer recording COVID data, and COVID is surging in the US.
Also there was apparently a massive antivax campaign being done by the pentagon that continued for like almost a year under his administration. I know it started under Trump but still....drug his feet stopping it.
