Sen. Elizabeth Warren, a Massachusetts Democrat, called for the breakup of Jeff Bezos’s Amazon following a report that the online retail giant manufactured rip-off products and orchestrated product searches in India, according to a tweet Warren posted.

“These documents show what we feared about Amazon’s monopoly power — that the company is willing and able to rig its platform to benefit its bottom line while stiffing small businesses and entrepreneurs,” she said Wednesday. “This is one of the many reasons we need to break it up.”
