On April 26, a former official of the U.S. Antitrust Department said on Monday that U.S. regulators are unlikely to prevent Tesla CEO Elon Musk from acquiring twitter p> < p > < / P > < p > bill Baer, who was once in charge of the antitrust Department of the U.S. Department of justice, also said that regulators may investigate Musk's acquisition of Twitter and "try to review whether the transaction poses risks to competitors and consumers" p> < p > it is reported that Twitter and musk need to submit this huge transaction of about $44 billion to the U.S. Department of justice or the Federal Trade Commission (FTC) for review p> < p > the US Department of justice and FTC are responsible for supervising various acquisition transactions. Officials of both institutions have said that they will pay close attention to how mergers and acquisitions will lead to the increasing concentration of the technology industry. FTC has filed a lawsuit against Facebook on the grounds that the company's acquisition of instagram and WhatsApp stifled market competition p> < p > but Musk's acquisition of Twitter is not the kind of deal that regulators usually intervene in. Bell said U.S. regulators usually intervene when companies buy competitors. Sometimes, when an acquisition would unfairly benefit another part of the acquirer's business, regulators would also block the transaction. Musk's electric vehicle manufacturer Tesla and space company SpaceX do not compete with Twitter, but it is unclear whether musk will somehow connect them with Twitter, a personal social media platform p> < p > "in my opinion, musk currently holds a large stake in the two companies," said William Kovacic, former chairman of FTC. "It's hard to see how much Twitter has to do with the two companies." p> < p > spokesmen for the US Department of justice and FTC declined to comment. (Chen Chen) < / P > < p >
