A minor hydraulic problem forced President Donald Trump 's helicopter to make an unscheduled landing in Britain before his departure for the United States, the White House said Thursday.

White House press secretary Karoline Leavitt said the issue briefly delayed Marine One's return to London Stansted Airport after leaving the prime minister's country residence.
