WASHINGTON (AP) -- A powerful government panel has failed to reach consensus on the possible national security risks of a nearly $15 billion proposed deal for Nippon Steel of Japan to purchase U.S. Steel. The Committee on Foreign Investment in the United States on Monday sent its long-awaited report to President Joe Biden, a longtime opponent of the deal. Some federal agencies represented on the panel were skeptical that allowing a Japanese company to buy an American-owned steelmaker would create national security risks. That's according to a U.S. official familiar with the matter. Both Biden and President-elect Donald Trump opposed the merger and vowed to block it.
