Robert F. Kennedy Jr. said in an interview that he wishes there were a law to "punish" people who are skeptical of or deny global warming.
"I don't think there is a law that you can punish these politicians under," Kennedy said, adding that skeptical politicians are "selling out the public trust."
Kennedy was very critical of the conservative Koch Brothers and politicians who fail to act on climate change, calling them "contemptible human beings." "Those guys are doing the Koch Brothers' bidding and are against all the evidence of the rational mind, saying global warming does not exist," he said.
