United Steelworkers President David McCall has filed a motion to dismiss a lawsuit brought against him by U.S. Steel and Nippon Steel, alleging the lawsuit is an attack on the union's First Amendment rights. The lawsuit, filed by U.S. Steel and Nippon Steel, accuses McCall, Cleveland-Cliffs, and its CEO Lourenco Goncalves of illegal actions aimed at preventing the $14.9 billion acquisition of U.S. Steel by Nippon Steel. The acquisition faced opposition from former President Joe Biden, who initially blocked it on national security grounds, though the enforcement was delayed until June. Amidst this legal battle, President Donald Trump is set to meet with U.S. Steel CEO David Burritt, as Nippon Steel expresses hope that the upcoming meeting between Japanese Prime Minister Shigeru Ishiba and Trump will advance their acquisition plan. Nippon Steel's Vice Chairman Takahiro Mori emphasized that their proposal aligns with Trump's goal of strengthening the U.S., and they are actively engaging with the Trump administration to push forward the acquisition. Additionally, a group of U.S. consumers has filed a lawsuit against Nippon Steel, seeking to block the acquisition on the grounds that it would reduce competition and increase prices for steel-related products.
