BJP said it was the Congress vice president's responsibility to answer questions over "scams" that occurred during his party's rule.
"Our target is corruption not individuals. Congress has been a champion of corruption and it is natural that it will be held accountable.
"Charges have been framed in many such cases like coal scam and 2G scam and he is himself an accused in the National Herald case. He should not play victim and rather answer questions," party's national secretary Shrikant Sharma said.
The BJP, he said, came to power on the plank of making India corruption-free and is now working to eradicate corruption.
He claimed Congress stood "exposed" in AgustaWestland deal after bribe-givers were convicted by a court in Italy. Sharma said the Congress government was forced to cancel the deal after corruption in it was exposed in 2012 and now the party will have to answer questions about it.
