"Senator Obama did not want to have a trip to see our wounded warriors perceived as a campaign event when his visit was to show his appreciation for our troops, and decided instead not to go," said retired Maj. Gen. Scott Gration, who advises Obama on national security matters.
Gration said the Pentagon told Obama's campaign that the military would consider the visit a campaign event.
But the Pentagon insisted it had been ready to welcome Obama at the hospital -- without his campaign staff or accompanying reporters.
"We advised that Sen. Obama would be welcome to visit Landstuhl or any other military hospital in his capacity as a U.S. senator, but his campaign staff would not," Pentagon press secretary Geoff Morrell said.
