While he officially marked Sept. 11 at the Flight 93 memorial in Shanksville, Pennsylvania, President Donald Trump also used the 17th anniversary of the terrorist attack to cryptically praise his lawyer.

Trump called Rudy Giuliani — his personal attorney who served as the mayor of New York City on 9/11 — a “TRUE WARRIOR” whose “leadership, bravery and skill must never be forgotten.”

About an hour later, the President posted a puzzling tweet noting how many years its been since the massive terrorist attack. Trump also pumped a fist into the air as he approached a crowd of fans upon landing in Johnstown, Pennsylvania to attend a 9/11 memorial service, according to New York Times photographer Doug Mills.
