WASHINGTON — Responding to the Hillary Rodham Clinton e-mail controversy on Sunday, potential presidential candidate Lindsey Graham said he has never sent a single message using the technology.

“I don’t e-mail,” the Republican senator said on NBC’s “Meet the Press.’’ “You can have every e-mail I’ve ever sent. I’ve never sent one. I don’t know what that makes me.”

Graham said the controversy over Clinton’s use of private e-mail as secretary of state raised questions about the messaging practices of other Obama Cabinet officials.

Graham appears to have had some company in shunning such technology. Janet Napolitano, the former Homeland Security secretary, said in 2013 that she did not use e-mail either, calling it “inefficient” and time draining.


Graham said he had confidence that Representative Trey Gowdy, a fellow South Carolinian leading a committee investigating the 2012 attack on the US diplomatic post in Benghazi, “will get to the bottom” of the matter.

Clinton representatives have denied wrongdoing in her e-mail practices, and she said she has asked the State Department to make her messages public. The department is reviewing the messages.

A former US ambassador who served during Clinton’s term as secretary of state said he was held to a different standard than she was when it came to e-mail.

Speaking on CNN’s “State of the Union,’’ Scott Gration said he resigned from the ambassadorship to Kenya in 2012 amid State Department criticism of his management and e-mail practices.
