Republican Sen. Lindsey Graham of South Carolina said his campaign was hacked by Russians.
"Our campaign vendor was hacked. We were told by the FBI in August that we were hacked in June," Graham told CNN.
Graham went on to say that he believes CIA reports that point a finger at the Russian government for hacking into the Democratic National Committee servers and stealing thousands of emails, which were then released to the public by hacktivist group WikiLeaks.
"I do believe the Russians hacked into the DNC. I do believe they hacked into [Clinton campaign manager John] Podesta's email account. They hacked into my campaign account. I do believe all the information released publicly hurt [Democratic nominee Hillary] Clinton, didn't hurt [President-elect Donald] Trump," Graham said. "But I don't think the outcome of the election is in doubt.”

Graham said he wants Russia to “pay a price” and have the U.S. impose “crippling sanctions.”
"They're trying to destabilize democracy all over the world. Not just here," Graham said. "Here's what we should do. We should tell the Russians that on no uncertain terms, you interfere in our elections, we don't care why, we're going to hit you and hit you hard, we're going to introduce sanctions, it'll to be bipartisan."
Graham also took to Twitter to call for more action against Russia.
“Russian hacking during the US presidential election is not a Republican or Democrat issue. It's an American issue. We must stand together,” Graham wrote.
