Bestselling author Stephen King over the weekend revealed the one possible plot twist in the Donald Trump presidency that truly gives him chills.

“The worst thing that I could think of is that this guy would get a third term because he’s basically an idiot, isn’t he?” King told MSNBC’s Ali Velshi in an interview that aired on Saturday. “I mean, he doesn’t read.”

King, a longtime critic of the president, said Trump believes he can’t do anything wrong.

“That is a dangerous thing,” King said. “He is basically, I don’t want to use the word ‘crazy,’ because I don’t really think that he is, but he’s certainly dangerous.”

Velshi has asked King about a Q&A he did for The Guardian last month in which the author was asked to give the Trump presidency an ending.
