Sen. John McCain (R-AZ) brought up Russian hacking today at the Senate confirmation hearing for Rep. Mike Pompeo (R-KS), President-elect Donald Trump's nominee to lead the CIA. 

McCain wanted to know what Pompeo believes it will take to deter Russian President Vladimir Putin from further compromising U.S. national security through cyber attacks. 

He said the U.S. currently has "no policy" on how to treat cyber attacks, instead looking at it on a "case-by-case basis." 

Pompeo agreed with the assessment, promising to work on an overall policy and strategy for cyber-security. 

McCain then asked whether Pompeo thinks the United States has the capability to "adequately respond" to cyber attacks. 

"This is an amazing nation with incredibly smart people. If given a policy directive to achieve the directive you're describing, I am confident America can do that," said Pompeo, declining to talk in open session about the actual capabilities of the intelligence community.

On "Fox & Friends" this morning, Rudy Giuliani said he will be heading up a new cyber security committee that will brief Trump.
