Last week, the House Judiciary antitrust subcommittee issued document requests to tech giants Google, Facebook, Amazon and Apple that could see each of the companies’ respective e-discovery teams putting in some long hours over the next few weeks.

The list of materials the tech companies have been tasked with providing is both extensive and wide-ranging: financial statements, memoranda, spreadsheets and executive communications pertinent to various acquisitions or internal business decisions. They are expected to be delivered to the House Judiciary subcommittee no later than October 14.
