Graham noted that the Russians hacked Democratic emails and used social media to pit "one American against the other" in the 2016 election, saying that "an attack on one party" should be considered "an attack on all."

"Can you imagine what we would be saying if the Russians or the Iranians hacked into the presidential team of the Republican Party? This is a big deal," he said. "It’s not just a few Facebook ads. They were very successful in pitting one American against the other during the 2016 campaign by manipulating social media."

"And they actually got into the campaign email system of the Democratic Party," Graham continued. "An attack on one party should be an attack on all. The Russians are up to it again. And here’s what I tell President Trump: Everything we've done with the Russians is not working. We need more sanctions, not less.”

Graham, the chairman of the Senate Judiciary Committee, also said his committee would work with the Senate Intelligence Committee and Senate Homeland Security and Governmental Affairs Committee to "harden our infrastructure against Russia or anybody else interfering in 2020."

"The takeaway for me is they were very involved in the 2016 election, they’re coming at us again. I’d like to stop them. And one way to stop them is to make them pay a price," he added.

Senate Republicans have pushed back on Trump's efforts to lift sanctions against a number of Russian companies.
