Letterman Joke Turned Into Political Ad

In recent years, the late-night comedy shows have become a source of some of the edgiest political commentary on television. Now, a joke from a recent David Letterman monologue has even found its way into a political ad.

"President Bush is asking Congress for $80 billion dollars to rebuild Iraq. And when you make out that check, remember there are two L's in Halliburton," Letterman quipped earlier this month.

American Family Voices, a Democratic-leaning activist group, uses the Letterman joke as a lead-in to a television ad campaign accusing the Bush administration of cronyism and Halliburton of war profiteering.
