President Trump on Monday became the first sitting U.S. president to visit the Western Wall.

Trump, wearing a yarmulke, was accompanied on a tour of the wall by first lady Melania Trump, daughter and adviser Ivanka Trump and son-in-law and adviser Jared Kushner. Trump was seen placing his hand on the wall.

Trump’s visit to the Jewish holy site in the Old City of Jerusalem follows conflicting comments from inside the Trump administration on its position regarding who claims sovereignty over it.
