May 17 (Reuters) - Japan's Nippon Steel's ( NISTF ) vice

chairman and key negotiator for the U.S. Steel deal,

Takahiro Mori, will travel to Pittsburgh, Pennsylvania next week

to meet with local staff and elected officials, Bloomberg News

reported on Friday, citing people briefed on the matter.

In December, Nippon Steel ( NISTF ) offered nearly $15 billion to take

over U.S. Steel, drawing resistance from both President Joe

Biden and Donald Trump, as well as the United Steelworkers (USW)

union.

To win support from the USW, Nippon Steel ( NISTF ) has pledged to

move its U.S. headquarters to Pittsburgh, where U.S. Steel is

based, offering commitments on job security and additional

investments if the deal goes through.

Nippon Steel ( NISTF ) and U.S. Steel did not immediately respond to

Reuters requests for comment.
