"The Simpsons" creator Matt Groening responded to the criticism in an interview with "TV Guide", in which he said he did "research on the ecological damage caused by clear-cutting and over-logging it's really appalling". Jackie Lang, a timber industry activist in Salem who helped lead the protest against the Fox network and Groening, said she was appalled by Groening's response, and "He will be sorry he ever made it." Jake Hogan, supervising producer of the show, defended Groening: "[The episodes are just little stories, little comedies—stories that make people laugh." On October 15, 1991, Groening issued another statement the public, in which he said: "So now a few lumber companies have joined the nuclear power industry, right-wing preachers and high-ranking Republicans in attacking "The Simpsons". We must be doing something right. I must point out "The Simpsons" is a cartoon show—not "60 Minutes". Later in the show, the same lobbyist proposed drilling for oil in Teddy Roosevelt's head at Mount Rushmore. Please don't tell the oil companies about this."
