Horror writer Stephen King would so relish watching President Donald Trump debate the border wall issue with another critically acclaimed author that King offered in a tweet Saturday to pay $10,000 to see it happen.

King was responding to a tweet by Don Winslow, author of a new book coming out later this month called The Border. The book is the final offering of Winslow’s fictional trilogy on drug wars involving the Mexican cartels.

Winslow has researched extensively life at the southern border for his books. He says he has walked “every mile” of it. He believes that Trump’s wall comes from “cuckoo land” and that the president has concocted a “fictional emergency” stringing together a handful of real events to create a fake world of chaos and crime.

“The narrative that Trump and his allies create is a flat-out lie about chaos on the border, when the people who live there, as I do, have reported the opposite,” Winslow wrote last month in New York Magazine.
