UP CM Yogi Adityanath on Tuesday claimed Congress chief Mallikarjun Kharge keeps mum on the death of his mother and sister in an attack by Razakars as he feared losing Muslim votes. Days after Kharge criticised the seer-turned-politician on his saffron attire and "Batenge to Katenge" slogan, Adityanath launched a strong counterattack at a poll rally in Amravati.
