Jammu, Jan 28 (ANI): Congress leader Ghulam Nabi Azad on Wednesday filed nomination papers for Rajya Sabha in Jammu. Azad said that National Conference and Congress have been together since the fight for freedom of India so it is not new if they again join hands. He added that the comments of US President Barack Obama on religious cooperation was a master stroke as he gave a lesson to the government that no country can progress until people from all religions are taken along.
