Donald Trump has sent the Club for Growth a cease and desist letter aimed at stopping the conservative outside group from airing a set of attack ads against him in Iowa.

The letter comes a week after the Club for Growth unveiled a set of 30-second ads in Iowa attacking Trump as just another politician who supports liberal policies.

“I am not surprised the dishonest, irrelevant and totally failing Club for Growth has resorted to attacking the definitive front runner, especially after I refused to contribute to their pathetic group,” Trump said in a statement. “We will be releasing my current tax proposal, which is a major decrease in taxes, in the next week and will continue to expose the two faced hypocrisy of the Club for Growth and the problems groups like this perpetuate within a broken Washington, D.C.”
