Two Democrats on the Committee on Energy and Commerce sent a letter on Wednesday to Jeff Bezos demanding answers about safety issues regarding AmazonBasics-branded products.

Chairman Frank Pallone and consumer protections subcommittee Chairwoman Jan Schakowsky sent the letter to Bezos, requesting a response by Oct. 21 to address reports that many of the defective products “were never recalled and continue to be sold” or were deleted. The two called Amazon’s oversight of its products “grossly inadequate.”
