In a press release to the media, the

ACLU and ACLU of Pennsylvania said the

Red Lion Area School District will permit Wolfe and his girlfriend, Taylor Thomas, to attend Saturday night's prom.

Red Lion Area Senior High School Principal Mark Shue had threatened to bar Thomas, a 2011 graduate of the school, from attending the prom after she criticized Shue in an online petition.

Thomas launched the petition to urge the school to allow Wolfe to run for prom king. Wolfe earlier this week learned that his name had been stripped from the prom king race and put under the running for prom queen.

Wolfe had made repeated requests to school administrators to be allowed to be listed under his gender identity.

Shue reportedly deemed the language in the post by Thomas as dangerous.

The ACLU and ACLU of Pennsylvania on Friday sent Shue a letter urging him to allow Wolfe to wear the black cap and gown worn by male students at graduation and to be announced by his male name.

Wolfe's father, William Stambaugh, told The Associated Press that he has concerns about the couple's safety at the dance.

"I'm probably going to wind up going along, just to make sure that things don't get out of hand," Stambaugh said Friday.
