President Trump participated in a Memorial Day wreath-laying ceremony at Arlington National Cemetery on Monday to honor fallen service members and their families, promising those gathered that Americans “will never forget our heroes.”

The time-honored tradition at the Tomb of the Unknown Soldier dates back 150 years, with all of Trump’s modern predecessors participating in the annual ceremony. In remarks delivered from the hallowed grounds, Trump praised several veterans in the crowd and offered words of condolence to Gold Star families whose sons and daughters were killed overseas.
