Tom Brokaw on Monday gave the one word he said best describes the state of the 2016 Iowa caucus cycle.

“Wacko,” the legendary broadcaster said in an interview with WHO-TV, which aired Tuesday. “We’ve never seen anything like it.”

“I think where we are began with 9/11. I think it really unmoored the country,” Brokaw continued. “There was a succession of events after that that separated people about what they’re expectations of America were.”

He cited the Great Recession and rise of the Islamic State as two specific events that contributed to where the country is now, while adding that Americans are still “grasping for something to believe in.”

Brokaw, who openly criticized Republican candidate Donald Trump’s “dangerous proposal” to temporarily ban Muslims from entering the U.S., said it’s “stunning” how Trump has “said so many things that are patently not true” with little to no impact on his popularity.

“I don’t remember a time when we’ve seen that kind of thing happen in American politics,” Brokaw said.
