Here's a detailed description of the event from The Blaze.

Excerpt: Witches plan to cast a spell on Donald Trump and his supporters Friday night

The ingredients for the spell include a bunch of household items such as “an unflattering photo of Trump,” a “small bowl of water,” a “pin or small nail” and an “ashtray or dish of sand.” After all the necessary preparations, participants are instructed to chant together to “the spirits of Earth, Wind, and Fire,” “heavenly hosts” and “Demons of the infernal realm” with supplications that Trump will utterly fail and do no harm. The spell also targets Trump supporters, as the chant includes binding “all those who enable his wickedness, and those whose mouths speak his poisonous lies.”
