The government, however, dubbed the disruptions in Parliament over the issue as only a "pretext" to stall passage of the GST bill.
"Please explain to the country and the people of India, how much money of Lalit Modi has come into your bank account and that of your family. Please simply disclose this and the House will function," Rahul Gandhi said.
"We also agree that Parliament must function. But, we have raised a basic issue. We have said, and I have said it three times, Sushma Swaraj ji, the Chief Minister of Rajasthan and the Chief Minister of Madhya Pradesh have carried out in some cases illegal acts. In Madhya Pradesh there are murders happening and our Prime Minister does not feel it necessary to comment on them.
"He praises the Chief Ministers. He completely ignores the fact that the future of thousands of people in Madhya Pradesh has been destroyed by his Chief Minister. He completely ignores the fact that there is a business relationship between a criminal and his Chief Minister of Rajasthan," Rahul said as the logjam in Parliament continued over protests by Congress.

With disruptions rocking Parliament, Finance Minister Arun Jaitley blamed Congress president Sonia Gandhi and Rahul for stalling the proceedings.
He attacked Congress' top leadership for its "stubbornness" and alleged that they wanted India's growth story to suffer by obstructing the GST bill's passage.
"The assessment in the government is that there are not many in even Congress pushing this logic that House should not run. Only their top two leaders... Have been stubborn on it. (They say) Parliament should not function, legislations should not be passed. If there is harm to the country, to the system let it be," the Leader of the Rajya Sabha told reporters.
Asked about Rahul Gandhi's charge that Lalit Modi had paid money to Swaraj's family and that she should disclose the transactions, Jaitley said anybody can make such "unfounded" allegations.
