Barr Says Justice Dep't Exploring 'Widespread Concerns' About Tech Firms

Attorney General William P. Barr signaled that the Justice Department plans to step up its scrutiny of Silicon Valley, exploring new legal tools to probe companies for their privacy abuses and the way they police content online. Barr didn’t mention companies such as Amazon, Facebook and Google by name, but his speech — delivered to state law enforcement officials in Washington — amounted to the latest high-profile warning for Silicon Valley at a moment when major tech companies already are under investigation for their business practices.
