NASCAR has now brought a counterclaim against the teams and Curtis Polk — a 23XI co-owner who has advised Jordan for decades.

NASCAR's revenue-sharing charter system is under threat of being disbanded according to a Wednesday counterclaim filed by the stock car series against Michael Jordan-owned 23XI Racing and Front Row Motorsports that singles out Jordan's longtime business manager.

NASCAR sued 23XI Racing and Front Row Motorsports, saying in court documents that the two companies want to eliminate the charter system.
