A Republican super PAC is refusing the demand from President Obama's attorneys to take down an ad featuring his image.

The pro-Trump group maintains that the TV ad, which has been airing in South Carolina, ”is a lawful expression of political speech."

"CDP will not only refuse to take 'Enough Empty Promises' down but will distribute this advertisement to an additional 50,000 South Carolina Democratic primary voters," the Committee to Defend the President wrote in a letter responding to Obama's cease-and-desist letter.
