Bill Maher on Friday angered President Donald Trump and the Environmental Protection Agency over an aggressive action by the administration aimed at rolling back climate change regulations.

“Trump has always said the whole climate change thing is a hoax,” Maher said on “Real Time.” “He said that scientists are ‘stupid people.’ According to him, the idea that greenhouse gases cause climate change has no basis in reality.”

The comedian joked: “He thinks it’s just nonsense that people made up out of thin air to get rich. You know, like cryptocurrencies.”

The day before, the Trump administration overturned a 2009 scientific finding that carbon dioxide and other greenhouse gases pose a danger to public health. The finding was the legal basis for almost all climate regulations for power plants, vehicles and other pollution sources.

“And yes, your EPA director, Lee Zeldin, said this is the only, this is a quote, ‘the largest deregulatory action in American history,’ Maher said. “That’s probably true. Also the biggest idiotic movement in American history.”

Later in the episode, which aired the day before Valentine’s Day, Maher talked about a different kind of “dick.” The host argued that what women “really want” is for men to “grow up and start being men again,” and used Taylor Swift’s engagement to Kansas City Chiefs tight end Travis Kelce as a prime example.

“Taylor Swift went from writing songs about what a jerk this guy was to her, and what a jerk this guy was to her, to what a jerk this guy is,” he said, in an apparent reference to the pop star’s song “Wood,” which is believed to be about the football player’s penis.

Claiming that Taylor came out with “a procession” of “America-tortured metrosexual poets in Europe,” Maher concluded: “The minute he got some old-school heartwood, it was game over.”
