When Arvind Kejriwal formed his political party earlier this month, he had promised to "expose corrupt leaders." So far, he has focused mainly on Robert Vadra, the son-in-law of Congress president Sonia Gandhi, and union Law Minister Salman Khurshid. His next disclosure, which he is expected to announce today, is likely to focus on BJP president Nitin Gadkari. But he also mocked the party, telling it not to worry much, because politicians always get away scot-free.
