Mike Huckabee is leaving Fox News after six-and-a-half years to explore a repeat presidential run.

The former Arkansas governor announced the news on his personal website and will make it official Saturday at 5 p.m. PT on the final episode of his political talkshow “Huckabee.”

“Tonight I will do more than just say goodnight. I will say goodbye,” he wrote. “This is the last edition of ‘Huckabee’ on the Fox News Channel. It’s been the ride of a lifetime, and I have never had so much fun in my life.”

Huckabee won the 2008 Republican Iowa caucus before losing the Republican presidential nomination to Sen. John McCain. He joined Fox News that same year as a commentator and regular contributor.

Huckabee also asked audiences to “stay tuned” until spring to learn about his next political move as he couldn’t “rule out another presidential run.”

“There has been a great deal of speculation as to whether I would run for president,” Huckabee wrote. “If I were willing to absolutely rule that out, I could keep doing this show. But I can’t make such a declaration. I won’t make a decision about running until late in the spring of 2015, but the continued chatter has put Fox News into a position that is not fair to them, nor is it possible for me to openly determine political and financial support to justify a race. The honorable thing to do at this point is to end my tenure here at Fox.”
