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.

The U.S. Steel and Nippon deal continues to be a point of contention between labor and the presidential administration.

Pittsburgh's Action News 4 anchor Andrew Stockey sat down with Republican Senator Dave McCormick prior to his event in Pittsburgh's South Park neighborhood Monday.

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.

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.
