Sen. Cory Gardner (R-Colo.) will introduce a bill next Congress to create a select Senate committee to deal with cybersecurity issues.

Gardner has previously called for a special cybersecurity committee, Politico reported Monday night, but his plan to create it via legislation is new.

The plan comes one day after Senate Democratic Leader Charles Schumer (N.Y) and Sens. John McCain (R-Ariz.), Lindsey Graham (R-S.C.) and Jack Reed (D-R.I.) sent a letter calling for GOP leadership to create a new select committee on cybersecurity to investigate Russian hacking of the presidential election.

{mosads}The letter, and Gardner’s push, set up a potential conflict with Majority Leader Mitch McConnell (R-Ky.).

Last week, McConnell rejected calls for a special committee, arguing that the Senate Intelligence Committee should take the lead as a matter of “regular order.”

The debate over an investigation was sparked by a CIA assessment that reportedly found Russian hackers tried to help President-elect Donald Trump win the election. They did so, intelligence analysts believe, by leaking documents that hurt Hillary Clinton’s presidential campaign while holding back information stolen from the GOP. 

Senior intelligence officials have said Russian President Vladimir Putin was personally involved in leaking sensitive hacked information during the campaign, though Trump and his top aides have disputed those conclusions.
