Perry Jokes About Gaffe From Last Debate

SPARTANBURG, S.C. (AP) — Texas Gov. Rick Perry isn't forgetting about the Department of Energy this time around.

In Saturday's debate, Perry jokes about his gaffe from a debate four days ago, when he forgot the third Cabinet department he would eliminate if elected president.

Perry says he's glad moderator Scott Pelley of CBS News remembered to ask him about the Energy Department.

Pelly says he's had some time to think about it.

"Me too," Perry cracks back.

Perry has used humor this week to try and deflect his mistake, even stopping by the David Letterman show in New York. Perry says he wants to eliminate Education, Commerce and Energy Departments.

Republicans were debating for the second time in four days in South Carolina, the first-in-the-South primary state.
