Jaiswal, who was here to take part in a protest against power crisis, said the matter is already under CBI investigation.
On the issue of Congress nominee for PM post, Jaiswal said the decision in this regard is always taken by party's top leadership and there is no point discussing these things now.
Jaiswal further said the JPC report on 2G scam has established the fact that both the Prime Minister and Finance Minister had no role in the entire matter.
