Newt Gingrich, an avid Donald Trump supporter, talked about dreams of one day building a colony on the moon during his run for presidency, but the current GOP presidential nominee’s advisor Roger Stone claims the moon landing never even happened.

A report from Media Matters revealed that if your scroll through Stone’s Twitter feed, you’ll find that the ultraconservative conspiracy theorist said the moon landing was “a hoax … shot in a warehouse in New Jersey.”

The comment came during an exchange when Stone criticized President Barack Obama’s attire at an event. Comedian Charlie Currie replied by pointing out that by that logic, Americans would have never stepped on the moon. Stone replied by claiming they didn’t. Currie simply relied with an, “Oh.”

This is just a long list of conspiracy theories to come from Stone. He also claims the Clintons are responsible for the murder of four people and personally killed John F. Kennedy with the help of President Lyndon Johnson. Of course he also believes a tabloid story about Ted Cruz’s father being connected to Lee Harvey Oswald, who he also connects to the Kennedy assassination.

According to a 2009 New York Times article, Stone is not alone in believing the moon landings were faked. Six percent of Americans agree with him.

There “is no credible evidence to support such views, and the sheer unlikelihood of being able to pull off such an immense plot and keep it secret for four decades staggers the imagination,” the Times says.
