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.

U.S. Steel and Japan’s Nippon Steel sued the United States government on Monday in a last-ditch attempt to revive their attempted merger after President Biden blocked it last week on the basis that the transaction posed a threat to national security.

The companies argued in a lawsuit announced on Monday that Biden violated the Constitution by blocking the merger via a sham national security review that deprived the companies of their right to a fair process.

By blocking a Japanese company’s takeover of U.S. Steel, President Joe Biden says he is protecting good jobs in the American heartland

Joe Biden said the deal would create "risk for our national security and our critical supply chains." President-elect Trump also opposed the takeover.
