A Texas high school sophomore's parents might sue after the school booted the student from campus for wearing a John Edwards for 2008 president T-shirt.

Pete Palmer, a sophomore at Waxahachie High School, says he didn’t think he was doing anything wrong wearing the political shirt to school.

But according to the Waxahachie Independent School District dress code, students can't wear shirts with political slogans.

“T-shirts, other than WISD clubs, organizations, sports, or spirit t-shirts, college or university t-shirts or solid-colored t-shirts, are prohibited," according to the policy.

Palmer's parents argue the policy is inhibiting free speech.

“It’s a First Amendment constitutional right that people have fought and died for and I don’t know why he should give it up just because Waxahachie thinks it would be okay or neat for him to do so,” Paul Palmer said.

School officials cite the dress code policy and disagree that it is an attempt to stifle free speech.

“It was an opportunity for us to continue to try and maintain a safe and orderly environment. The dress code gives us the tools to make a decision on what is right and what isn’t,” said Thomas J. Collins, Waxahachie Independent School District superintendent.
