While the majority of steelworkers rallied behind Nippon Steel’s proposed $14.9 billion purchase of U.S. Steel, both the current and incoming administrations are poised to reject it, writes David J. Lynch for The Washington Post.

The Japanese company, which is willing to pay $14.9 billion for U.S. Steel, has pledged to spend an additional $1 billion on upgrades to plants in Pennsylvania.

If the deal falls through and the upgrades are not implemented, U.S. Steel said it will de-emphasize these antiquated facilities, “putting thousands of good-paying union jobs at risk.”

“This incredible deal will solidify our jobs for decades to come,” said Jason Zugai, a local United Steelworkers union leader.

However, both Joe Biden and Donald Trump oppose the deal which many steelworkers consider to be the last chance to save the aging mills in Pennsylvania’s Mon Valley.

The Committee on Foreign Investment in the United States sent out a letter to both parties, noting it had “identified risks to the national security of the United States arising from the Transaction.” The Treasury-led committee is expected to recommend the president to torpedo the deal on December 23.
