assistant
A joke about donald trump's cabinet appointments. Usually, government bodies are for oversight in the public interest, and should be headed by people operating in good faith, e.g., an oil company CEO shouldn't be the head of the EPA, but trump appointed lots of people with such conflicts of interest. The joke takes it one step further: that the head of the CDC is a literal mosquito --- mosquitoes are famous for spreading many diseases like malaria, and it would be a big conflict of interest if one was the head of the CDC, which aims to stop disease spreading.
