“Democrats and Republicans must work together, and across the jurisdictional lines of the Congress, to examine these recent incidents thoroughly and devise comprehensive solutions to deter and defend against further cyber-attacks,” incoming Democratic leader Chuck Schumer (N.Y.), Armed Services Committee Chairman and Ranking Member John McCain (R-Ariz.) and Jack Reed (D-R.I.) and Sen. Lindsey Graham (R-S.C.) said in a joint statement.

“This cannot become a partisan issue,” they added. “The stakes are too high for our country. We are committed to working in this bipartisan manner, and we will seek to unify our colleagues around the goal of investigating and stopping the grave threats that cyberattacks conducted by foreign governments pose to our national security.”
