A former Republican state lawmaker wrote a scathing letter to Texas Gov. Greg Abbott (R) on Thursday that slammed him for “pandering to idiots” who believe that a planned U.S. military exercise is cover for a forcible takeover of the state.

In a letter obtained by the Dallas Morning News, Todd Smith, who served in the state legislature for 16 years, wrote that he was “livid” about Abbott’s request for the State Guard to monitor the military’s upcoming training exercise, dubbed “Jade Helm 15.”

“I am horrified that I have to choose between the possibility that my Governor actually believes this stuff and the possibility that my Governor doesn’t have the backbone to stand up to those who do,” Smith wrote.

“I am appalled that you would give credence to the nonsense mouthed by those who instead make decisions based on internet or radio shock jock driven hysteria,” he added. “Is there ANYBODY who is going to stand up to this radical nonsense that is cancer on our State and Party?”
