Piyush Goyal accuses opposition parties of pressurising Rohit Vemula's mother for political gains

The statements of Rohith Vemula's mother are all before us, I believe there was an effort made to pressurise the mother to retract from what she had said, probably again on the pretext of giving her some money: Piyush Goyal 

I received info that even Congress President took them (Vemula's family) to stages & asked them to make statements. It should be exposed what was the intention behind it & what was offered. Rahul Gandhi should apologise for doing petty politics on pillar of lies: Piyush Goyal
