Away: U.S. President Barack Obama waves before he departs the White House aboard Marine One bound for New York today
Speaking to the New York Daily News, a highly placed Bush insider said: 'He doesn't feel personally snubbed and appreciates the invitation, but Obama's claiming all the credit and a lot of other people deserve some of it.
'Obama gave no credit whatsoever to the intelligence infrastructure the Bush administration set up that is being hailed from the left and right as setting in motion the operation that got Bin Laden.
'It rubbed Bush the wrong way.'
The President has steered clear of even mentioning the Bush team's efforts to capture Bin Laden, only hinting at the previous administration when he said: 'Over the last 10 years, thanks to the tireless and heroic work of our military and our counter-terrorism professionals, we've made great strides.'
Bush was name checked only once during Sunday night's historic speech, when he added: 'I've made clear, just as President Bush did shortly after 9/11, that our war is not against Islam.'
Obama had invited Bush to today's ceremony, a gesture Bush turned down.
Speaking to the paper, another source said Bush felt the invitation: 'was for the benefit of Obama, and Obama withheld credit from people Bush believes deserved it.'
