Addressing a crowd in South Carolina, GOP frontrunner Donald Trump blasted President Barack Obama for the carbon footprint he leaves by traveling in Air Force One.

“He talks about the carbon footprint, and yet he will fly a very old Air Force One, an old Boeing 747, with the old engines spewing stuff. So he’s got a problem with the carbon footprint.”

“You can’t use hairspray, because hairspray is going to affect the ozone,” Trump continued. “They don’t want me use to use hairspray, they want me to use the pump… I want to use hairspray. They say don’t use hairspray, it’s bad for the ozone.”

Use of CFCs as an aerosol propellant in household products like hairspray and deodorant was successfully phased out under the Montreal Protocol.
