Barstool Sports’ founder said he would send two customers to tour a former Nazi concentration camp after they allegedly engaged in antisemitic behavior at a Barstool pub in Philadelphia, then later retracted that offer for at least one of them because he said the person was denying responsibility for what happened.

The incident at a Philadelphia bar owned by the Barstool Sports founder Dave Portnoy comes amid a surge of antisemitic episodes in the United States.
