"The president's trip to Arlington came about a month after he received criticism for not visiting the national cemetery on Veterans Day.
And that, in turn, came after a visit to a World War I cemetery in France was scuttled due to poor weather."
There was talk that the trip in France was cancelled due to an assassination attempt. I don't recall hearing about the other scuttled visit, but perhaps it was similar.
