"I don't wear a toupee,” Trump told a laughing crowd at an event in Greenville, South Carolina. “It's my hair. I swear."
He then decided that the situation required an “inspection” -- so he called a woman from the crowd onto the stage to tug at his hair.
"Come here! We're gonna settle this," he said. "Just come on up here. You have to do an inspection here. This is getting crazy."
“Yes, I believe it is,” the woman told the crowd when asked if the hair was real.
The real estate mogul was careful to say that "we don't want to mess it up too much because I do use hairspray."
Trump had just cited a New York Times article naming Los Angeles Spanish language radio show host Ricardo Sanchez, who had started calling Trump "el hombre del peluquín" - the man of the toupee.
Trump insisted the hair was his own: "So I'm on the front page of the New York Times and the first sentence says I wear a toupee. And I don't. I swear to you, I don't."
