WASHINGTON/TOKYO -- Nippon Steel has begun an unprecedented legal battle against the U.S. government over the company's proposal to acquire U.S. Steel, pursuing a two-pronged strategy in hopes of uncovering evidence of collusion among the government, the steelworkers union and a rival steelmaker to thwart the deal.

In a lawsuit against President Joe Biden and the U.S. government, Nippon Steel asks the court to set aside Biden's order issued Friday blocking the acquisition and to instruct the Committee on Foreign Investment in the United States (CFIUS) to conduct a new review of the deal.
