Please note the 'and', not a 'to'. The volcano that has been causing havoc all week in Europe's air space prevented Obama from attending as planned. While that 'excuses' Obama from not attending, perhaps playing golf instead was not the best idea. At least that would have been the tone of the story if it was Bush instead of Obama...
"A massive volcanic plume covering most of Europe forced President Obama to cancel a Sunday trip to Poland to attend the funeral of the nation's president. But the last-minute change left an opening in his schedule, so the president headed to the links for a round of golf instead.
On a cool but sun-drenched Sunday, the president and three golfing companions went to Andrews Air Force Base to play 18 holes. It is the 32nd time Mr. Obama has played golf since taking office Jan. 20, 2009, according to CBS Radio's Mark Knoller."
