Please don't think I'm defending Obama - but here's some information for your troop: such letters must be REQUESTED. The Bush White House had a request form on their web site; I know because we requested and received one from George W. Bush for our son. Presumably the next POTUS will also have such a request form. Governor Rick Perry of Texas and both Texas senators also have forms to request Eagle recognition letters available at their web sites. My hubby is scoutmaster of a large troop; they make it their business to request letters for the boys. Perhaps the parent doing this job in your troop "retired"?
Hope this helps future Eagles in your Troop.
Yours in Scouting,
