Trump vows to block U.S. Steel's takeover by Japan's Nippon Steel

President-elect Donald Trump is pledging to block Japan's Nippon Steel from buying U.S. Steel, a $14.9 billion deal announced a year ago that is now under review for its potential impact on U.S. national security.

"I am totally against the once great and powerful U.S. Steel being bought by a foreign company, in this case Nippon Steel of Japan," Trump wrote on Truth Social late Monday. "Through a series of Tax Incentives and Tariffs, we will make U.S. Steel Strong and Great Again, and it will happen FAST!"

He added, "As President, I will block this deal from happening. Buyer Beware!!!"
