Mike Huckabee, the former governor of Arkansas, announced Saturday night that he was ending his cable talk show and would make a decision about a presidential bid this spring.

Mr. Huckabee, a Republican, used his weekly Fox News program, “Huckabee,” to reveal that he was leaving the network as he considers a second campaign for the White House.

“As much as I have loved doing the show, I cannot bring myself to rule out another presidential run,” said Mr. Huckabee, 59, who also sought the Republican nomination in 2008. Adding a bit of drama, he said, “As we say in television, stay tuned!”

He said he would make a decision on running “late in the spring.”

Mr. Huckabee, a Baptist pastor turned politician, won a following with conservatives during his first campaign, and he has become even more widely known since then thanks to his presence on the Fox network.
