Nippon Steel Corp. received US approval for its $14.1 billion acquisition of United States Steel Corp., to create one of the world's largest steel companies. The deal includes a national security agreement and substantial monetary investments.

President Trump on Friday cleared the way for Japan-based Nippon Steel to potentially acquire U.S. Steel, though details about the structure of the deal — including a possible "golden share" held by the federal government — remain unclear.

President Donald Trump would have unique influence over the operations of U.S. Steel under the terms of the investment being made by Nippon Steel.
