President Trump has called off a planned visit to a U.S. military cemetery outside Paris due to what the White House claims is “logistical difficulties caused by the weather.” The White House said Saturday that Chief of Staff General John Kelly and Chairman of the Joint Chiefs of Staff General Joe Dunford will visit the Aisne-Marne American cemetery instead after Trump canceled the trip. While rain was reported in the area, it was not immediately clear how that would prevent a helicopter ride. The cemetery is located at the site of a 1918 battle in which American and French forces fended off German troops during World War I, a major event in U.S. Marines Corps history in which at least 1,800 troops died. Trump was meant to take part in a wreath-laying ceremony at the site for Veterans Day weekend. Nicholas Soames, a grandson of Winston Churchill, lashed out at Trump on Twitter for the move. “They died with their face to the foe and that pathetic inadequate @realDonaldTrump couldn’t even defy the weather to pay his respects to The Fallen,” Soames wrote.
