Rahul Gandhi and Smriti Irani were locked in a slanging match after the Congress vice-president's criticism of the ban on an IIT-Madras study groupfollowed by protests by NSUI provoked the HRD minister into an angry outburst. Rahul's criticism of the ban was followed by a protest by the students' body, headed by its chief Roji John, outside Irani's residence. In retaliation, an incensed Irani targeted Rahul with a series of tweets. "Yesterday, you told NSUI to create disorder where there is order. Today, your goons come to my house as I'm away at work," she said and challenged Rahul for a debate on governance and education.
