Trump needs to put his brand on Kool Aide.
If you are referring to Jonestown, they drank Flavor Aid, not Kool-Aid.

Jonestown Massacre
The drink became linked to the Jonestown mass murder-and-suicide when it was learned that the cyanide poison taken by or forcibly administered to the commune’s members was placed in Flavor Aid. Large barrels filled with the grape variety, laced with the cyanide and a variety of tranquilizer drugs, were found half-consumed amidst the hundreds of bodies. Kool-Aid, rather than Flavor Aid is usually mentioned in connection with the Massacre, due to its status as a genericized trademark. This factual error has even spawned the figure of speech “to drink the Kool-Aid”. Film of Jonestown many months before the Massacre show stocks of both Flavor Aid and its leading competitor within the commune’s storehouses, so it is quite possible that both drinks were used as carriers for the poison.
