PELLA, Iowa (CNN) - Republican presidential candidate Mike Huckabee said Wednesday that embattled Idaho Sen. Larry Craig has, as "the old saying goes..."a lot of 'splainin to do."
When asked if he thought Craig should resign, Huckabee told CNN, "[It] depends on what turns out to be the facts, and I don't want to prejudge until they're established."
"It's certainly not a good thing," Huckabee continued. "And I think the guilty plea is what makes it a little bit dicey for him. If he believed it was an innocent misunderstanding, then I think most Americans would say that you fight it, you don't just roll over and plead guilty."
The former Arkansas governor was in Pella, Iowa at his first campaign stop in the state since his surprise second place finish at the straw poll on August 11.
