FILE - In this file photo dated Oct. 17, 1957, President Dwight Eisenhower, second left and first lady Mamie, second right are flanked by their royal guests, Britain's Queen Elizabeth II and her husband, Prince Philip, at the White House, in Washington. US President Trump enjoys flouting diplomatic rules and expressing himself in bold and sometimes mocking tweets and comments, but that side of his personality is unlikely to surface when he takes tea Friday, July 13, 2018 with Queen Elizabeth II. The president and his wife Melania are not expected to make waves during the visit with the 92-year-old monarch, who has met every U.S. president since Dwight Eisenhower with the exception of Lyndon Johnson, who never visited Britain while in office.
