Washington (CNN)Sen. Lindsey Graham says he's never sent an email.
The South Carolina Republican and potential 2016 presidential contender offered to share everything he's ever sent with NBC's "Meet the Press" host Chuck Todd -- but said there's not really much to turn over.
"You can have every email I've ever sent -- I've never sent one," he said. "I don't know what that makes me."
Still, Graham, who's hammered both Clinton and President Barack Obama over foreign policy, said he wants Clinton's emails vetted by an "independent group," rather than the State Department or her staff, to determine what should be released.
"This is big in this regard: Did she communicate on behalf of the Clinton Foundation as secretary of state? Did she call the terrorist attack in Benghazi a terrorist attack?" Graham said. "I want to know."
