Dinner host Doug Dechert reportedly responded to the question by screaming “the climate hoax!” which allegedly woke up his friend Anthony Haden-Guest, who had been taking a nap.

According to a report from Page Six, a nasty argument about climate change at a Robert F. Kennedy Jr. press dinner left guests stunned… and breathing through their mouths.

While another attendee tried to change the subject, further questions about climate change during the event caused Dechert and Haden-Guest to yell at one another again, Page Six reported.
