Nippon Steel offered Washington a "golden share," which gives the government oversight over some decisions, to get approval for its takeover of U.S. Steel.

President Trump on Friday cleared way for Nippon Steel purchase of U.S. Steel, including unusual control for the president.

The U.S. government's ownership of a golden share in U.S. Steel will not block Nippon Steel from taking any management action that it deems appropriate, the Japanese steelmaker's CEO said on Thursday.
