Delhi Chief Minister Arvind Kejriwal on Monday told the Supreme Court that he made a mistake by retweeting an allegedly defamatory video circulated by YouTuber Dhruv Rathee related to the BJP IT Cell. A bench of justices Sanjiv Khanna and Dipankar Datta, without issuing notice on a plea of Mr Kejriwal challenging a Delhi High Court order which upheld summons issued to him as an accused in the criminal defamation case, asked the complainant whether he wanted to close the matter in view of the chief minister's apology.
