Bengaluru (Karnataka), May 30 (ANI): Former President Pranab Mukherjee's acceptance of Rashtriya Swayamsevak Sangh's (RSS) invitation to attend a meet at its Nagpur headquarters has stirred uproar within Congress. Former Union Railway Minister and senior Congress leader CK Jaffer Sharief wrote a letter to Mukherjee asking him to reconsider his decision.
