“Our campaign vendor that we used was hacked,” Graham told CNN's Wolf Blitzer in an interview. “We were told by the FBI in August that we were hacked in June.”
Graham’s campaign vendor adds to the growing list of high-profile political entities that intelligence officials believe were accessed by Russian hackers during the 2016 presidential campaign. Among those hacked were the Democratic National Committee and John Podesta, former chairman of Hillary Clinton’s presidential campaign.
Graham said he believes some content from his account was leaked but he personally doesn’t use or send emails.
“I think some of it was actually released but I've never sent an e-mail,” Graham said. “And I'm not about to start now.”
Graham stressed the hacking of his campaign vendor’s account is another attempt from the Russian government to undermine the U.S. democratic process.
“They're trying to destabilize democracy all over the world,” Graham said. “We should tell the Russians, in uncertain terms, you interfered in our elections, we don't care why. We're going to hit you and hit you hard.”
