George W. Bush has rarely had a moment in the spotlight since his presidency - Associated Press White House Correspondent Ben Feller notes he hasn't been to the White House in two years, when he was helping out with Haiti humanitarian relief in January 2010.

Obama has been indirectly talking trash about the former President in his re-election campaign, criticizing the past administration for its handling of the country's finances and foreign policy.

Bush made a lukewarm endorsement of Republican Mitt Romney earlier this month when he was pressed on the matter, ABC News reported.
