Boeing's tanker scandal is featured in a new TV ad from Sen. John McCain's presidential campaign. McCain led the fight to stop Boeing from getting a $23 million Air Force contract after questions were raised about conflict of interests between the aircraft company and a Pentagon official.

McCain's efforts sparked an investigation which resulted in jail sentences for Boeing's chief financial officer and a top procurement official with the Air Force. The campaign calls the ad "Guts." You can watch it here.

ANNCR: When special interests and bureaucrats conspired to spend 30 billion of your tax dollars on a defense contract boondoggle, everyone looked the other way.

Everyone except one man.

One man has the experience to know it was wrong and the courage to stop it.
Corruption exposed.

Billions saved.

Wrongdoers jailed.

All the candidates for president say they'll stop wasteful spending.

One man has actually done it.

JOHN MCCAIN: I'll stop wasteful spending by Congress. Restore trust in government.

JOHN MCCAIN: I'm John McCain and I approve this message.
