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.

The companies said they had entered into an agreement with the U.S. government to alleviate any national security concerns.

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.
