he CEOs of Amazon, Apple, Facebook and Google took a rare turn in the congressional spotlight on Wednesday, with lawmakers posing a critical — and potentially perilous — question for the technology titans: Are you guys too powerful? For the executives, the issue of their companies' market dominance comes at a delicate time — amid an economic catastrophe that has wiped out businesses large and small while adding billions to the coffers of an industry that critics have dubbed Big Tech.  In addition, the hearing culminates a year-long investigation by the House Judiciary Committee into the foursome, America's largest companies by market value even before the coronavirus pandemic reached U.S. shores in February and sent some of their stock prices skyrocketing. The four CEOs are testified virtually before the House Judiciary subcommittee on antitrust. Follow along below for updates as it happened.
