The state's director of science curriculum said she resigned this month under pressure from officials who felt she gave the appearance of criticizing the instruction of intelligent design.
The Texas Education Agency put Chris Comer on 30 days paid administrative leave in late October, resulting in what she described as a forced resignation.
The move came shortly after Comer forwarded an e-mail announcing a presentation being given by the author of Inside Creationism's Trojan Horse. In the book, author Barbara Forrest says creationist politics are behind the movement to get intelligent design theory taught in public schools. Comer sent the e-mail to several individuals and a few online communities.
Comer, who held her position for nine years, said she believes evolution politics were behind her ousting.
"None of the other reasons they gave are, in and of themselves, firing offenses," she said.
