The Satanic Temple, founded in New York, plans to rally in the Florida capital, Tallahassee, Jan. 25, to thank Scott for signing a bill that temple spokesman Lucien Graves said "does a lot to support religious diversity."
In a statement, the Satanic Temple said the Florida law "has reaffirmed our American freedom to practice our faith openly, allowing our Satanic children the freedom to pray in school."
In response to an ABC News inquiry about the Satanic Temple rally, Scott's press secretary said in an email: "This is a great country. Everyone has a voice."
