Congress MP Rahul Gandhi will be "undoubtedly exonerated" by the Enforcement Directorate and "the truth will prevail", brother-in-law Robert Vadra said today. Calling accusations of money laundering 'baseless', he said the action by the central probe agency is to harass the opposition because it questions the Centre. Speaking to NDTV, Mr Vadra called the case a 'witch-hunt' and narrated his personal experience with the probe agency.
