A recently published investigation reveals that JD Vance's adviser, Kofsky, had a presence on Reddit under the username PsychoticMammal. The account posted about drug use and addiction, including references to opioids, cocaine, and kratom. The investigation found multiple connections between the online persona and Kofsky's offline life, including employment at the same ski resort and attendance at the same high school.
