‘They have too much power’: US lawmakers grill Big Tech as Trump weighs in

A much-anticipated congressional hearing featuring the CEOs of four of America’s largest tech firms kicked off on Wednesday afternoon in a confrontation that promises a healthy dose of political theatre, while also offering a window into the thinking of lawmakers trying to rein in Big Tech.

Facebook Inc’s Mark Zuckerberg, Amazon.com Inc’s Jeff Bezos, Alphabet Inc-owned Google’s Sundar Pichai and Apple Inc’s Tim Cook–who together represent about $5 trillion of the U.S. economy–are appearing via videoconference before the House Judiciary Committee’s antitrust panel.

President Donald Trump, who has clashed with several of the biggest tech companies, on Wednesday threatened to take action against them.
