U.S. President Donald Trump walks out of the Oval Office of the White House to board Marine One on the South Lawn in Washington, D.C., U.S., on Friday, June 30, 2017. Trump demanded that South Korea give U.S. automakers 'a fair shake' to sell more cars there and also stop exporting 'dumped steel' during talks at the White House with its newly elected president, Moon Jae-in.
