Twitter hack triggers investigations and lawmaker concerns

SAN FRANCISCO — Fallout from Twitter’s massive security breach intensified Thursday, as authorities launched investigations and lawmakers from both sides of the aisle called for more information on a widespread hack of high-profile accounts.

The FBI will lead a federal inquiry into the hack, it said in a statement Thursday. Gov. Andrew M. Cuomo (D) directed New York state to start a probe of the incident, saying the hack is “deeply troubling” particularly in light of the approaching elections. And lawmakers spoke out, including Sen. Edward J. Markey (D-Mass.) who said in a statement the country needs “strong cyber security standards.”
