President Biden blocked Japan's Nippon Steel from buying U.S. Steel last week, earning the approval of the United Steelworkers union, which desperately wanted the deal crushed. But steel workers themselves may be less than enthused.

Nippon Steel Chief Executive Eiji Hashimoto says the top Japanese steelmaker is standing firm on its proposed $15 billion acquisition of U.S. Steel.

Separate lawsuits from Nippon Steel and U.S. Steel target President Joe Biden as well as a steelworkers union head and a rival steelmaker’s CEO.
