Former congressman Dick Armey has quit FreedomWorks, the conservative group he helped bring to national tea party prominence. 

Armey confirms that he wrote a letter to FreedomWorks President Matt Kibbe on Nov. 30, resigning from the group, as first reported by Mother Jones. He told the Post that he does not know who leaked his resignation letter.

"We accepted his letter of resignation and we wish him well," FreedomWorks press secretary Jackie Bodnar said. 

Max Pappas, the group's former vice president for public policy and government affairs, has also left, along with campaign director Brendan Steinhauser, who traveled the country training activists for the group.
