The White House posted a photo:

May 5, 2011
“A few days after the mission against bin Laden, the President traveled to New York City to meet with families of the 9/11 victims. He also visited at Engine 54, Ladder 4, Battalion 9 Firehouse. The firehouse, known as the “Pride of Midtown,” lost 15 firefighters on 9/11 — an entire shift and more than any other New York firehouse. Here, the firefighters offer an impromptu toast to the President in honor of their fallen comrades during a lunch at the station house.”
