After Congress MP Priyanka Gandhi called IIT Madras Director Prof V Kamakoti a "gaumutra expert", BJP MP Anurag Thakur took a jibe at her and her brother Rahul Gandhi. "Rahul and Priyanka...perhaps...are consuming something that affects the proper functioning of the brain...Maybe gaumutra will cure them," he said. Prof Kamakoti is part of PM Narendra Modi's exam reform task force.
