Shiv Sena (UBT) MP Priyanka Chaturvedi during her address in Rajya Sabha on Tuesday said that the biological voters of this country taught the person who calls himself non-biological a lesson. "Even Lord Krishna didn't call himself non-biological and is called 'Devaki-Putra' (son of Devaki)," she added. Earlier, Rahul Gandhi said that unlike all humans, PM is non-biological.
