(CNN) - Conservative talk show host Mike Huckabee said Mitt Romney's campaign was not authorized to use his voice in a new web video released Monday.
The ad, "Huckabee," featured quotes from the former Arkansas governor's radio show last week when he called on Republicans to stop criticizing Romney's corporate career at Bain Capital.

"This in no way is an endorsement of any candidate," Huckabee said in a statement Monday night. "Any attempt by anyone to imply an endorsement of a candidate or opposition to a candidate is not true."
The 2008 Republican presidential candidate added that he will not offer support for any candidate until the Republican nomination has been clinched.
Huckabee was quoted in the ad saying it was "surprising" to see Republicans pounce on Romney's experience as the executive of a private equity firm that bought and streamlined companies.
"They ought to know, that if downsizing can turn around a failing company, then at least it prevents all the jobs from being lost, and sets up a stronger company that can grow and start re-hiring,” Huckabee said in the ad.
While the spot shows images of Huckabee, it does not clarify whether or not the conservative heavyweight was supporting Romney.
