After Washington, D.C. sues Amazon, other states reportedly consider antitrust actions

Antitrust clouds are gathering over Amazon in a week that saw the retail giant face its first U.S. lawsuit alleging competition-squelching practices just before the company announced its second-biggest acquisition ever.

Washington, D.C., filed a suit against Amazon Tuesday, accusing the U.S.' largest online seller of monopolistic behavior. The suit claims that Amazon's dominance allows it to impose onerous terms on third-party sellers on its platform that drive up prices for online shoppers everywhere. Now, other state enforcers are examining Amazon for potential violations, according to Bloomberg. Attorneys general in Connecticut, Massachusetts and Pennsylvania are looking at Amazon's practices, the outlet reported, citing anonymous people familiar with the matter.
