Congress President Sonia Gandhi's son-in-law Robert Vadra on Sunday hit out at the BJP for constantly targeting him. In an interview he said, "I am being subjected to a political witch-hunt. BJP's attacks against me are a political tool whenever they need to divert public attention. I have always conducted my business transparently in accordance with the law." Reacting to this, BJP leader Nalin Kohli said, "He hasn't cleared any allegations till date. This interview has raised more questions."
