House lawmakers investigating the market dominance of Big Tech are asking Amazon CEO Jeff Bezos to testify to address possible misleading statements by the company on its competition practices.
In a letter to Bezos on Friday, leaders of the House Judiciary Committee are holding out the threat of a subpoena if he doesn't agree voluntarily to appear.
Amazon used sensitive information about sellers on its marketplace, their products and transactions to develop its own competing products, according to a recent Wall Street Journal report.
An Amazon executive denied such a practice in statements at a committee hearing last July, saying the company has a formal policy against it.
Amazon spokesmen had no immediate comment.
