John McCain to Obama: 'Heroes don't brag'

Republican Senator and decorated prisoner of war John McCain criticized President Obama Tuesday night, saying he has shown a lack of leadership in his handling on key terror issues - specifically the killing of Osama bin Laden.

“I hope this isn't viewed in the wrong way but heroes don't brag,” McCain told ABC7’s Jay Korff. “Heroes don't brag."

Obama has been accused by some for using the death of bin Laden for political gain. In one instance, Obama’s campaign released an ad questioning whether Mitt Romney would have killed bin Laden.

Romney accused Obama of politicizing the fleeting national unity that came with the death of bin Laden, the 9/11 terror mastermind, according to the Associated Press.

On Tuesday. McCain took a similar stance.

"His continuous bragging about taking out bin Laden, you know, most of the guys I know would say, let somebody else talk about that," McCain said.

McCain's comments come as new insight is revealed into the foiled plot to blow up an American jet on the anniversary of bin Laden's death.

U.S. and Yemeni officials say the supposed would-be bomber at the heart of an al-Qaida airliner plot was actually an informant working for the CIA.

The revelation, first reported by The Los Angeles Times, shows how the CIA was able to get its hands on a sophisticated underwear bomb well before an attack was set in motion.

Officials say the informant was working for the CIA and Saudi Arabian intelligence when he was given the bomb. He then turned the device over to authorities. Officials say the informant is safely out of Yemen.
