AAP spokesperson Priyanka Kakkar criticised P Chidambaram's 'Operation Blue Star was a mistake' remark, saying Congress cannot erase its sins with statements. She alleged that leaders involved in the 1984 "organised massacre" of Sikhs still roam with Rahul Gandhi. "If they had learnt from their mistakes, Kamal Nath, Jagdish Tytler, and Sajjan Kumar wouldn't have been given positions," Kakkar said.
