A bipartisan group accused the company of lying about their business practices.

Yesterday, a bipartisan group of five members of the House Judiciary sent a message to the top brass of Amazon.com Inc. The message accused the executives, including the company’s founder, Jeff Bezos, of knowingly lying to the United States Congress on matters related to their business practices. According to the message, the group of lawmakers is considering “whether a referral of this matter to the Department of Justice for criminal investigation is appropriate.”

The message cites an investigation conducted by Reuters which uncovered an internal campaign within Amazon to rig search results on their platform to push their own brands and products over third party sellers. As Amazon has publicly denied these allegations in front of Congress before, the message states that the investigation “directly contradicts the sworn testimony and representations of Amazon’s top executives – including former CEO Jeffrey Bezos.”

“At best, this reporting confirms that Amazon’s representatives misled the Committee. At worst, it demonstrates that they may have lied to Congress in possible violation of federal criminal law,” the message explains.

An Amazon spokesperson issued a response to the letter, dismissing its claims and the claims of the Reuters investigation. “Amazon and its executives did not mislead the committee, and we have denied and sought to correct the record on the inaccurate media articles in question.”

“As we have previously stated, we have an internal policy, which goes beyond that of any other retailer’s policy that we’re aware of, that prohibits the use of individual seller data to develop Amazon private label products. We investigate any allegations that this policy may have been violated and take appropriate action.”
