Congress leader Pawan Khera appeared before the Guwahati Crime Branch for questioning in connection with a forgery and defamation case filed by Assam CM Himanta Biswa Sarma's wife, Riniki Bhuyan Sharma, over allegations that she possessed three passports. Riniki had earlier denied the claims, calling them "false, fabricated and politically motivated." Riniki filed the case in Guwahati on April 5.
