Congress General Secretary Priyanka Gandhi Vadra today hit back at the BJP for the recent "father-son" barb by Assam Chief Minister Himanta Biswa Sarma on her brother and Congress MP Rahul Gandhi. "They should not have said that about my mother. She is the widow of a martyr. My mother has given her life to this country," Priyanka Gandhi told NDTV during an election campaign in Uttar Pradesh's Rae Bareli.
