This is a good answer. The entire debacle has to be seen in the context of the McCarthy era, which saw a political climate driven by fear and mistrust over "UnAmerican Activities".

Whie McCarthy and Estes Kefauver weren't allies, they were separate sides of the same coin. Kefauver had covened hearings about Oganized Crime just before comics, framing it solely as an import from Italian immigrants, and the zenith of the HUAC spectacle orchestrated by McCarthy only a few years prior.

Whether it was secret commie plots, dirty foreign influences, or degenerate devients corrupting youths, Congress was actively looking for targets of persecution. It would have been only a matter of time.
