President Trump said Mesabi Metallics will invest $15 billion to build what the White House describes as the largest steel plant of its kind in U.S. history, located in Iowa. A White House official told CNBC that production is expected to begin in 2030, with an initial phase producing about 7.5 million tons annually and supporting up to 6,000 construction jobs. Mesabi, based in Minnesota, said the plant would produce entirely American-made steel.
