Pompeo Says Russia 'Pretty Clearly' Behind Cyberattack, Prompting Pushback From Trump

Since news of the SolarWinds hack surfaced nearly a week ago, high-ranking Trump administration officials had remained largely silent about the cyberattack that involved at least half a dozen federal agencies. On Friday, Secretary of State Mike Pompeo broke that silence, becoming the most prominent administration official to blame Russia for the attack.

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