From the White House transcript of President Trump’s speech to the Turning Point USA Student Action Summit in West Palm Beach on Saturday, December 21, 2019:

“We’ll have an economy based on wind. I never understood wind. You know, I know windmills very much. I’ve studied it better than anybody I know. It’s very expensive. They’re made in China and Germany mostly — very few made here, almost none. But they’re manufactured tremendous — if you’re into this — tremendous fumes. Gases are spewing into the atmosphere. You know we have a world, right? So the world is tiny compared to the universe. So tremendous, tremendous amount of fumes and everything. You talk about the carbon footprint — fumes are spewing into the air. Right? Spewing. Whether it’s in China, Germany, it’s going into the air. It’s our air, their air, everything — right?”
