WASHINGTON (AP) – Facebook internal company documents are being deployed against CEO Mark Zuckerberg by lawmakers asserting that the company has gobbled up rivals to squelch competition. Rep. Jerrold Nadler, the Democrat who heads the House Judiciary Committee, told Zuckerberg at a hearing Wednesday that documents obtained from the company “tell a very disturbing story” of Facebook’s acquisition of the Instagram messaging service. He says the documents show Zuckerberg called Instagram a threat that could “meaningfully hurt” Facebook. The questioning came at a congressional hearing that also featured Amazon CEO Jeff Bezos, Apple CEO Tim Cook and Google CEO Sundar Pichai.
