SAN JOSE, Calif. (AP) — Four U.S. senators concerned about the sabotage of Silicon Valley's power grid and phone lines last April are asking federal officials if mandatory security standards are needed.
Democratic Sens. Ron Wyden, Harry Reid, Dianne Feinstein and Al Franken sent a letter Friday asking federal energy regulators to review whether requiring power companies to comply with what are now voluntary security standards would improve grid safety.
The letter came just days after former Federal Energy Regulatory Commission Chairman Jon Wellinghoff said the attack on the grid was an act of terrorism. The incident is under investigation by the FBI, which says it has found no indication of terrorism.
