(CNN) In the US and across the world, lawmakers and regulators are demanding answers from Facebook and Cambridge Analytica in the wake of a global scandal centered on the harvesting of the personal data of 50 million users. The information was then allegedly used to help in the digital campaigning efforts of President Donald Trump during the 2016 election -- a claim Cambridge Analytica denies. Adam Schiff, the ranking Democrat on the House Intelligence Committee, has demanded answers from both companies, even threatening the use of subpoenas "if necessary" -- though Facebook and Cambridge Analytica have both subsequently agreed to brief lawmakers. It's certainly right that Facebook and Cambridge Analytica should face some tough questions. Action from lawmakers and regulators after something makes global headlines is good, but it's not enough -- we need them to be out in front.
