Comedian Kunal Kamra took to Twitter to share a video of him asking questions to Arnab Goswami on a flight to Lucknow. "Are you a coward or a journalist or a nationalist," Kamra asked Goswami. "This is for Rohith Vemula's mother whose caste you were discussing on your show...Just become human...do that in your free time," he further told Goswami.
