David Letterman offered another apology to Sarah Palin Monday for a joke he told about her daughter. "I'm sorry about it and I'll try to better in the future," he said.


Palin supporter John Ziegler wants more from Letterman. "I think it's a good first step in the right direction, but I don't think it's enough."
