President Trump made history Monday during his trip to Israel. But what for? Trump became the first sitting U.S. president to place a note in Jerusalem's Western Wall. Trump, wearing a black yarmulke, stood alone with his hand on the wall for several moments before tucking a note deep between the cracks. Other presidents, like Barack Obama and the Bush's, visited as private citizens or as candidates. First Lady Melania Trump, daughter Ivanka Trump and son-in-law and adviser Jared Kushner joined Trump for the visit.
