A group of lawmakers led by Democratic U.S. Sen. Elizabeth Warren, D-Mass., is asking the Federal Trade Commission (FTC) to reject Amazon.com Inc.'s $1.7 billion deal to buy Roomba vacuum maker iRobot Corp., Axios reported on Thursday, citing a letter.
The FTC last week had asked Amazon and iRobot for more information on the e-commerce giant's buyout offer, which was announced in August.
Warren and the FTC did not immediately respond to Reuters' requests for comment.
According to a recent Politico report, the FTC had started an antitrust review of the deal earlier this month to see if it was illegally boosting the e-commerce company's market share in the connected device market.
