President Trump visited Israel’s Holocaust Museum and Memorial on Tuesday at the tail-end of his brief trip to the nation. During remarks at Yad Vashem, Trump called the Holocaust history’s “darkest hour.” “It was the most savage crime against God and his children, and it is our solemn duty to remember, to mourn, to grieve and to honor every single life that was so cruelly and viciously taken,” Trump said. The President and First Lady Melania Trump signed Yad Vashem’s guest book and left a short note about their time in the solemn space. The note read: It is a great honor to be here with all of my friends.
