Gary Johnson admitted to being an idiot in a video interview with the Guardian published on Thursday.

"I am an idiot," said the Libertarian presidential nominee early in his exchange with Paul Lewis, a reporter for the British newspaper. "I am the dumbest guy you've ever met in your whole life."

In the course of the five and a half minute video exchange, Johnson also acknowledged that he is "human" and claimed that his campaign is "phenomenal."

"Why are you even interviewing me?" he asked halfway through the exchange.

Johnson also suggested that Evan McMullin, an independent conservative candidate, is "ensuring that Hillary Clinton will win Utah" and discussed the possibility of wielding "a magic wand" that would allow him to eliminate most forms of taxation.

When pressed by Lewis about the fact that economists do not generally favor the abolition of the income tax, Johnson mentioned his support for the legalization of marijuana.

"But what's that got to do with your tax policy?" Lewis asked.

"It's leadership," Johnson said.

Before the interview began, Johnson shouted at an employee of HBO and discussed the possibility that he might "blow [his] brains out."
