President-elect Trump said "we ought to get on with our lives" in response to Sen. Lindsey Graham calling for sanctions against Russian President Vladimir Putin over cyberattacks during the presidential election.

"I think computers have complicated lives very greatly. The whole age of computer has made it where nobody knows exactly what's going on," Trump said Wednesday while speaking to reporters at his Mar-a-Lago estate in Palm Beach, Florida.

"We have speed, we have a lot of other things, but I'm not sure you have the kind of security we need. And I have not spoken with the senators and I will certainly will be over a period of time."

Graham said Wednesday that Congress will investigate Russian involvement in the elections.

"There will be bipartisan sanctions coming that will hit Russia hard, particularly Putin as an individual," the South Carolina senator warned.

Russia has denied accusations that it interfered in the U.S. election.
