Sens. Bob Menendez and Richard Blumenthal wrote a letter to Amazon CEO Jeff Bezos on Monday asking it to say whether people or algorithms are making decisions about what gets the “Amazon’s Choice” label.
They are worried that the Choice category can be manipulated via fake reviews and can mislead customers.
Amazon said it “worked hard” to ensure reviews were accurate and real.
The online retail giant has been given until 16 September to respond to the letter.
