Sarah Palin Accepts David Letterman's Apology

Palin said Tuesday that Letterman has the right to joke about whatever he wants to, and "thankfully we have the right to express our reaction."

"This is all thanks to our U.S. military men and women putting their lives on the line for us to secure American's right to free speech," she said. "In this case, may that right be used to promote equality and respect."

Although Bristol, an unwed mother, was the target of his joke, Letterman didn't name her when it was originally made on June 8.

It was "a coarse joke," ''a bad joke," Letterman told viewers. "But I never thought it was (about) anybody other than the older daughter, and before the show, I checked to make sure, in fact, that she is of legal age, 18."

"The joke, really, in and of itself, can't be defended," he declared.

If there's a misconception that he was making the joke about a 14-year-old, Letterman said he understands why people are upset. "I would be upset myself," he said.

"I feel that I need to do the right thing here and apologize for having told that joke," he said. "It's not your fault that it was misunderstood, it's my fault that it was misunderstood."
