Papa John's founder John Schnatter resigned as chairman of the company's board late Wednesday, after touching off a firestorm of criticism when he confirmed that he had used a racial slur during a conference call with a marketing agency.
Schnatter, a Donald Trump donor who had already stepped down as his company's chief executive in January after he said that NFL player protests were hurting his pizza sales, apologised after saying that the report that he had used the n-word in the May call, in the business magazine Forbes, was not in error.
"News reports attributing the use of inappropriate and hurtful language to me during a media training session regarding race are true," Schnatter said in a statement. "Regardless of the context, I apologise. Simply stated, racism has no place in our society."
Schnatter's resignation was announced in a brief statement Wednesday night from the national pizza company he had founded more than 30 years ago, but it did little to quell the growing cloud around the company.
Major League Baseball suspended a league-wide promotion it had with the company that allowed fans to get discounts on pizzas after players hit grand slams, while some teams like the Florida Marlins suspended individual partnerships they had with the brand, vowing to shutter stadium concession stands.
