Senators raised the stakes against some of America’s biggest tech companies on Wednesday, telling them they must take more comprehensive action against foreign actors misusing their platforms. “You created these platforms ... and now they’re being misused,” Sen. Dianne Feinstein (D-CA) told the top lawyers at Facebook, Google, and Twitter. “And you have to be the ones who do something about it — or we will.”

Feinstein’s remarks came during a blistering hearing of the Senate Select Intelligence Committee, which has been investigating Russian meddling interference in the 2016 election. It is the second of three hearings at which representatives for Facebook, Google, and Twitter will speak, following yesterday’s appearance before a Senate Judiciary subcommittee.
