The president of the conservative activist group FreedomWorks accused former House Majority Leader Dick Armey (R-TX) of trying to hijack the group as part of an “attempted hostile takeover” of the organization, according to documents obtained by Mother Jones.

In the memo, Matt Kibbe says Armey, who founded and led the group before resigning on Dec. 4, voted to oust Kibbe from the board in September. Kibbe said fellow board member James Burnley IV helped Armey carry out his plan of having him replaced by C. Boyden Gray on the board.

“Bottom Line: The Actions Of The Trustees Put FreedomWorks Values and Mission at Risk,” Kibbe wrote. “They have put personal and political agendas above the agenda of freedom.”
