Former Union Minister and Congress leader P Chidambaram has lauded former President Pranab Mukherjee for teaching the RSS about the lessons of nationalism and the idea of India. In a tweet, Chidambaram said that he was happy as Pranab told the RSS what is right about the Congress’ ideology. Pranab attended the RSS event in Nagpur on invitation from the RSS chief Mohan Bhagwat. But, there is a mixed response to Pranab’s speech from the Congress party leaders. Now, questions are being asked whether the Congress would tender apology to Pranab.
