A bipartisan group of House lawmakers investigating Amazon for possible antitrust violations have demanded that Jeff Bezos testify before Congress to address statements by the company that “appear to be misleading, and possibly criminally false or perjurious”.

“Although we expect that you will testify on a voluntary basis, we reserve the right to resort to compulsory process if necessary,” seven leaders of the House judiciary committee, including the chair Jerry Nadler, wrote in a letter to the Amazon CEO on Friday.
