In a Sunday interview on CNN’s “State of the Union,” Chris Krebs, the former director of the Cybersecurity and Infrastructure Security Agency, was asked by host Jake Tapper who was at fault for the breach.

“So, the way I look at it is, yes, it happened on my watch at CISA. And we missed it. A bunch of other folks missed it,” he responded…

“Everything I have heard, whether it’s from private sector cybersecurity threat intelligence experts, things I have heard out of Congress and the intelligence community, it’s Russia,” Krebs said.

“I mean, they’re exceptionally good at this, particularly the foreign intelligence service, the SVR. They’re good. They’re quiet. They’re deliberate. They’re patient and they’re careful,” he continued.
