Speaking to reporters here, he said he was not aware of any of his family member being possibly named by CBI in the second charge sheet in the scam.
"I don't know," he said to a question on reports that his daughter Kanimozhi, MP and wife Dayalu could be named.
The 87 year-old leader went on to add that the names will be revealed as the media would report it after the charge sheet was filed in a Delhi court.
Responding to reports about DMK's possible exit from the UPA cabinet in this connection, he shot back "Is that your desire?"
"Being a woman, you should not talk as if you are heartless," he said when women reporters persisted in asking him about 2G and his equations with the UPA.
Taking a dig at the media, he said they would report "the "slightest of dirt" on DMK, but said he would still continue to read the newspapers.
Former Telecom Minister A Raja had been arrested in connection with the alleged scam, and the investigating agency had questioned Dayalu and Kanimozhi in Chennai recently.
