WASHINGTON (Reuters) - U.S. President Donald Trump's defence secretary plans to visit Japan and South Korea next week, choosing the two close U.S. allies for his debut trip abroad as Pentagon chief, a U.S. official said on Tuesday, speaking on condition of anonymity.
James Mattis, a retired Marine general, was sworn into the Pentagon's top job shortly after Trump's inauguration on Friday.
