Rep. Adam Schiff (D-Calif.) was on Fox News Sunday this week, where he talked about the news that there had been an attack on a California power station back in April.

“It was a sophisticated attack, there’s abundant evidence of pre-planning,” he said.

Schiff said the country puts a lot of focus on cyber-security but may have taken its eye off less complicated attacks, like ones on substations.

He said the country should prioritize transformers and substations that would bring the greatest threats to the power grid, then branch out from there.
