President Donald Trump on Friday touted a "blockbuster agreement" between U.S. Steel and Japanese company Nippon Steel that he said would keep the iconic U.S. steelmaker in Pittsburgh -- though he previously opposed such a merger and offered few details on the specifics of the deal.

President Trump announced Friday he'll double steel tariffs from 25% to 50% during a visit at a U.S. Steel mill in the Pittsburgh area.

Speaking at a U.S. Steel plant in Pennsylvania, President Donald Trump touted his administration’s economic successes and promoted the “big, beautiful" budget bill.

President Donald Trump traveled to Pittsburgh Friday to celebrate a deal he once vowed to oppose - Japanese steelmaker Nippon Steel’s long-announced plans to buy iconic American steelmaker US Steel.

If the US gets a 'golden share' of Nippon Steel's takeover of US Steel, it would be the latest example of how Washington, D.C. increasingly has a say in the operations of major companies.
