CEDAR RAPIDS, Iowa (CNN) — Republican presidential candidate Mike Huckabee joked Tuesday that he was "very disappointed" he wasn't offered the job of attorney general to replace resigning Alberto Gonzales.

"They found out I didn't have a law license, [and] I only have an honorary law degree. So I guess that's why I wont be offered the position."

"Besides," he continued with a smile, "I've got a job I'm looking for now."

The former Arkansas governor made the comments at a press conference following his appearance at Lance Armstrong's LIVESTRONG Presidential Cancer Forum. Huckabee is one of only two Republicans to accept an invitation. Kansas Sen. Sam Brownback is the second.

Brownback said of Gonzales' resignation, "It was time, past time. He had lost his effectiveness as an attorney general. I'm hopeful we can move forward with a good nominee quickly so we can get somebody in that very important position in the government."
