CNBC^[1], 28 Sep 2026: "The Oval Office announcement with Mesabi Metallics, which began at 2 p.m. ET"; MPR News^[6] gives the same slot as "1 p.m. CT", which is 18:00 UTC.
President Donald Trump announced in the Oval Office at 2 p.m. ET on 28 September 2026 that Mesabi Metallics will invest about $15 billion in a steel plant in Iowa, which the White House calls the largest of its kind in US history and the first mega steel plant built in the country since the 1960s. The plant is due to start producing steel in 2030. Its first phase is put at about 7.5 million tons a year with up to 6,000 construction jobs, rising to 10 million tons a year and at least 1,750 permanent jobs. It will run on iron ore from Mesabi's new mine at Nashwauk on Minnesota's Iron Range, and Iowa lawmakers have discussed tax incentives for a plant in Lee County in the state's southeast. The announcement came weeks before the November midterm elections, as Trump pointed to his 50% steel tariffs as the driver of new US steel investment.

Legislative action date (2025-09-28) tracked by AI Data Center Legislation Tracker.^[1]
Fidelis New Energy proposed the 2,300+ acre Mountaineer GigaSystem (hydrogen + data center) campus in Mason County, WV. In March 2026, California-based Nscale acquired the project (Monarch Compute Campus) by buying American Intelligence and Power Corporation. Nscale immediately signed a memorandum of understanding with Microsoft to provide 1.35 GW of capacity for an AI data center using NVIDIA Vera Rubin NVL72 GPUs. Once fully built, capacity could reach 1GW (potentially expanding further), with up to $5B invested. WV state law HB 2014 stripped local zoning authority over data centers. Residents continue to raise concerns about water usage, noise, emissions, and lack of community input. First phase expected operational in 2028.
