Sen. Lindsey GrahamLindsey Olin GrahamSenate panel advances three spending bills Trump says he will sign executive order to end family separations Trump backs narrow bill halting family separations: official MORE (R-S.C.) said on Sunday that he has never sent an email.

"I don't email,” Graham, who’s considering a 2016 White House run, said on NBC’s “Meet the Press.” “You can have every email I've ever sent. I've never sent one."

“I don’t know what that makes me,” he added.

Graham’s comments came during a discussion of Hillary Clinton’s use of a private email account while she served as secretary of State, a practice that he said raised several questions.

“Did she communicate on behalf of the Clinton Foundation as secretary of State? Did she call the terrorist attack in Benghazi a terrorist attack in real time? I want to know,” he said.

“The one thing I’ll never agree to is let the State Department tell us what emails we’ll receive or let her or her team tell us. Some independent group should do that,” he added.

Sen. John McCain (R-Ariz.) last week admitted that he doesn't use email himself because "from time to time, I get a little emotional."

"I'm afraid that if I was emailing, given my solid, always-calm temperament, that I might email something that I might regret," McCain said on MSNBC, adding he prefers using a phone or tweeting.
