Much as anti-Covid-vaxxers want the explanation to be "Vaccine Injury", reappearing publicly so soon after his virtue-signal-booster is not very consistent with that wishful thinking.
I'm trying to figure out how Noisome "qualifies" for a booster. He's well under age 65, AFAIK, not especially overweight, and AFAIK has no significant health issues that would weaken his immune system. I don't recall the guidelines for boosters including a Virtue-Signalling by Prog Politicians qualification.
Are these children from his first marriage, from his affair with his chief of staff's wife, some other (not publicly known) GF-with-benefits, or his current wife?
