Speaking from a green energy summit in Austria, Arnold Schwarzenegger called on President Donald Trump to go green, suggesting he’d experience “a lot of victories.”

“Those of you who resist because you can’t imagine success without fossil fuels: we ask you to join us. Everyone. Also you, President Trump: Join us.” Referring to a comment Trump made on the campaign trail about Americans getting sick of winning, the former California governor added: “You said … you want to have so many victories that the American people will get sick and tired of winning. Well, if that’s really what you want then join us, because then you will have a lot of victories.”

This suggestion comes amid new Pew polling showing Millennials Republicans—born between 1981 and 1996—for the most part disagree with elder Republicans on a slate of issues, including the environment and climate change. More than one-third (36 percent) of GOP Millennials say the Earth is warming mostly due to human activity, double the share of Republicans in the Baby Boomer or older generations.
