Before poo pooing this as fake news, I can remember back during the H5N1 scare, as Safety, Health, and Environmental Manager of my petrochemical facility, I was on a Pandemic Response Plan task force, developing contingency plans for many facilities. There was significant DHS coordination, and I can clearly remember one of their contacts saying, that a response compilation document had been prepared for the hightest levels in government.
I obviously can't stand Biden, but I believe him on this one.
