Last April, when I was serving in the White House, President Trump paid tribute to the victims and survivors of the Holocaust by giving one of the most moving speeches of his entire presidency. During this speech, he powerfully proclaimed that, “We must never, ever shrink away from telling the truth about evil in our time … evil can only thrive in darkness.”

However, there still exists one early 20th-century atrocity that lives in darkness after all these years. Trump now has an opportunity to shine a light on the massacre of over 1.5 million Christian Armenians at the hands of the Ottoman Turks.
