Truth vs Hype: Nitin Gadkari - A valid defence?

But support for him came from S Gurumurthy, the RSS and BJP supporter and chartered accountant, who went into Mr Gadkari's balance sheets and gave him a clean chit. But on what basis was this clean chit given ? And does it answer the doubts about Purti Group's funding, or raise fresh ones ?
