Huckabee to make 2012 announcement

(CNN) – Current and former advisers to former Arkansas Gov. Mike Huckabee insist they do not know what he plans to announce Saturday on his Fox News show, fueling speculation he won't seek a second shot at the Republican nomination.

Signs have mounted for the last two years that Huckabee – while keen on staying in the political arena – has not been preparing to embark on a second national campaign.
