The entirety of President Obama's proclamation is as follows:

As a mark of respect for the memory of Army Corporal Frank W. Buckles, the last surviving American veteran of World War I, and in remembrance of the generation of American veterans of World War I, I hereby order, by the authority vested in me by the Constitution and the laws of the United States of America, that, on the day of his interment, the flag of the United States shall be flown at half‑staff at the White House and upon all public buildings and grounds, at all military posts and naval stations, and on all naval vessels of the Federal Government in the District of Columbia and throughout the United States and its Territories and possessions until sunset on such day. I further direct that the flag shall be flown at half‑staff for the same period at all United States embassies, legations, consular offices, and other facilities abroad, including all military facilities and naval vessels and stations.

IN WITNESS WHEREOF, I have hereunto set my hand this twenty‑eighth day of February, in the year of our Lord two thousand eleven, and of the Independence of the United States of America the two hundred and thirty-fifth.
