The BJP's missed call drive to stack up support for the controversial citizenship law, which has fueled protests across the country, got a booster shot today as Home Minister Amit Shah attended a public event in Delhi. Each person in his audience was asked to dial 8866288662, the phone number for the BJP's drive on the Citizenship (Amendment) Act (CAA). Those dialing the number would deliver their message of support directly to Prime Minister Narendra Modi, Amit Shah told the hundreds present for the launch of the 200-km Delhi Cycle Walk.
