ask[ing] the people of the United States to observe the Days of Remembrance of Victims of the Holocaust, April 23 through April 30, 2017, and the solemn anniversary of the liberation of Nazi death camps, with appropriate study, prayers and commemoration, and to honor the memory of the victims of the Holocaust and Nazi persecution by internalizing the lessons of this atrocity so that it is never repeated.The text of the Proclamation has been posted on Trump's Facebook page, but has not yet appeared on the White House website.
Yesterday the President also signed a Proclamation (full text) marking Armenian Remembrance Day. As pointed out by Hurriyet, consistent with past practice the Proclamation uses the Armenian term Meds Yeghern (Great Calamity) and avoids referring to the atrocities as a "genocide."
UPDATE: And here is the full text of President Trump's speech on Tuesday at the United States Holocaust Memorial Museum National Days of Remembrance.
