Papa John’s founder John Schnatter is punching back.

The pizza mogul who was accused of using a racial slur during an internal conference call in May is claiming the marketing firm that set up the call tried to extort $6 million from the chain to keep quiet about the slur.

“They wanted $6 million to make it go away,” Schnatter told a Louisville, Ky., CBS affiliate about Laundry Service, the Los Angeles-based marketing firm since fired by Papa John’s.

“‘If I don’t get my f–king money, I’m going to bury the founder,’ said one of the executives,” Schnatter told WLKY. “I’m not for sale,” Schnatter continued. “We held firm and they ran to Forbes, which printed it.”

Laundry Service declined to comment on the explosive charge, and Papa John’s did not return calls or e-mails.

Schnatter claims that Laundry Service, which was hired to provide public relations training, leaked the details about the conference call to Forbes only after its alleged extortion attempt failed.

The marketing firm made its demand about two weeks after the conference call, Schnatter told WLKY.

Schnatter has maintained that Laundry Service “pushed” him to say the n-word during the call.

Following the incendiary TV interview on Friday, Papa John’s issued a statement on Sunday, explaining that Schnatter, “is no longer a spokesperson for the company or the brand. The company has specifically requested that Mr. Schnatter cease all media appearances, and not make any further statements to the media regarding the company, its business or employees.”

The company went a step further and also evicted Schnatter from his office at the Louisville headquarters, a special committee of the chain’s board of directors said.

Schnatter will be forced to vacate the premises after the committee directed the company “to terminate a sublease agreement” that granted the 56-year-old executive the right to use certain space.

Schnatter has 90 days to move out of his memorabilia-rich tribute to his successful career. The office contains a horse statue covered in pizza ingredients, signed guitars, and his original 1971 Z28 Camaro — which he sold to fund the start-up of the chain in 1984, according to reports.

The outspoken executive has been in hot water since last week, when a transcript of an internal May conference call was leaked that revealed Schnatter had used the n-word.

Schnatter, no stranger to controversy, admitted he used the racial slur.

In January, the pizza mogul — who owns 30 percent of the $1.7 billion company’s shares — blamed the national anthem protests by NFL players for Papa John’s declining sales.

Papa John’s was a long-term NFL sponsor. The league parted ways with the chain after Schnatter’s comments. The executive also stepped down as CEO at that time.

The revelation of the n-word comments forced him to step down as chairman. Schnatter remains on the board.

Papa John’s shares closed down 4 percent, to $51.41.
