The White House wanted the U.S. Navy to move “out of sight” a warship named for the late Sen. John McCain, a war hero who became a frequent target of President Trump’s ire, ahead of the president’s visit to Japan last week, according to an email reviewed by The Wall Street Journal. [...]

A tarp was hung over the ship’s name ahead of the president’s trip, according to photos reviewed by the Journal, and sailors were directed to remove any coverings from the ship that bore its name. After the tarp was taken down, a barge was moved closer to the ship, obscuring its name. Sailors on the ship, who typically wear caps bearing its name, were given the day off during Mr. Trump’s visit, people familiar with the matter said.
