WASHINGTON (AP) — Federal regulators are ordering Amazon founder Jeff Bezos and CEO Andy Jassy to testify in the government’s investigation of Amazon Prime. The regulators rejected the company’s complaint that the executives are being unfairly harassed in the probe of the popular streaming and shopping service. The Federal Trade Commission issued an order denying Amazon’s request to cancel civil subpoenas sent in June to Bezos, the Seattle-based company’s former CEO, and Jassy. The order also sets a deadline of Jan. 20 for the completion of all testimony by Bezos, Jassy and 15 other senior executives, who also were subpoenaed.
