Sen. Lindsey Graham, R-S.C., said his campaign account was hacked by Russia earlier this year and that Russia should be punished for interfering in U.S. elections.

Graham mentioned the hacking in an interview with CNN in the larger context of concerns that people associated with the Russian government hacking into Democrat organizations’ emails.

“Our campaign vendor that we used was hacked,” Graham said. “We were told by the FBI in August that we’re hacked in June so this is — they’re trying to destabilize democracy all over the world.”

Graham said that he would introduce sanctions that name Russian President Vladimir Putin as an individual and that they would be bipartisan.

“This is not a Republican/Democratic issue,” Graham said. “I want to punish them for interfering in our elections, trying to destabilize the entire world.”

Graham has joined Senate Democrats in calling for an investigation into whether Russia tried to interfere with or influence U.S. elections.

President-elect Donald Trump rejected intelligence reports that say Russia tried to influence the election in his favor.

Graham pushed back when asked if Trump would accept sanctions on Russia.

“I don’t work for Donald Trump,” he said. “I’m in the legislative branch. We have the ability to formulate foreign policy, but he’s the commander in chief… I want to help reset the world when it comes to Russia.”
