Mamata Banerjee's Trinamool Congress has claimed to have "irrefutable evidence" that BJP goons are responsible for yesterday's violence at Amit Shah's rally and the vandalism at Vidyasagar College in Kolkata. The party, which met the Election Commission today, said they have submitted the videos, which have been doing the rounds on social media amid a blame game about who is responsible for the violence. "Amit Shah is a pathological liar... He did not have a fig leaf to do his press conference. Let him dispute my videos," said Derek O'Brien, senior TMC leader and parliamentarian, when asked about the BJP chief's accusation that the Trinamool has staged the event to malign his party.
