US Secretary of State Mike Pompeo said Friday that Russia was behind the devastating cyberattack on several US government agencies that also hit targets worldwide.

"There was a significant effort to use a piece of third-party software to essentially embed code inside of US government systems," Pompeo told The Mark Levin Show.

"This was a very significant effort, and I think it's the case that now we can say pretty clearly that it was the Russians that engaged in this activity."
