evidence: A state senator who was the 2022 GOP nominee for Pennsylvania governor has proposed legislation to outlaw experimental weather modification techniques falsely associated with the "chemtrail" conspiracy theory. [...] On the subject of chemtrails, Keith said there’s little evidence to support the conspiracy theory, with the main claim being that "airplane contrails look different." Keith added that if such a program existed, it would require a vast operation and tens of thousands of people. Keeping it secret would be impossible. "If such a program was intended to cause harm to their fellow citizens — as is alleged by people who believe in the chemtrails conspiracy — then people working in the program would have very strong personal motivations to reveal it," Keith said.
