May 21 (Reuters) - A powerful U.S. national security

panel known as CFIUS on Wednesday submitted a recommendation to

President Donald Trump on Nippon Steel's ( NISTF ) fraught $14.9 billion

bid for U.S. Steel, a person familiar with the matter said.

The submission complies with an executive order signed by

Trump that gives the President until June 5 to decide whether to

approve or scuttle the merger. Reuters could not learn the

content of CFIUS's recommendation.

The companies did not immediately respond to requests for

comment.
