Senator Paul encourages people to spread and catch Covid-19. His wife owns stock in a company which makes a treatment that helps with severe cases. Is that a conflict of interest?

I don't claim that he has encouraged the spread of Covid-19 in order to profit from that stock. I expect that he is motivated mainly by a callous political strategy. But this does show he knows that the disease is dangerous and likely to spread.

His wife bought the stock in February 2020, showing attentiveness to investment opportunities. It also means that they concealed the purchase for about 18 months. If he reported it now for an "annual disclosure", wasn't there a similar annual disclosure in 2020?
