An elementary school in Wrightstown, WI is under fire for allowing children to recite the Pledge of Allegiance in Spanish.

A parent of a kindergartner recently attended an event at Wrightstown Elementary School where the principal invited boys and girls to recite the pledge in either English or Spanish. That prompted the concerned mom to contact FOX News Radio affiliate WTAQ in Green Bay.

The mother, who asked not to be identified, shared a copy of a letter she wrote to the principal explaining her opposition to the issue.

"Not only does reciting this in Spanish insult our family as American citizens, it is disrespectful to the veterans who have defended our country," she wrote. "English is the primary language in this country. The Pledge of Allegiance was written in English and should be recited in English. No similar accommodations were made for other immigrant patterns in history nor should they be as long as the American flag is flying."

The principal of the school defended the Spanish recitation explaining that he wants Spanish-speaking students to understand the importance of the pledge.

"It is my responsibility as a principal in a public school to give every student the opportunity to learn and grow as a student, no matter what their race or religion," wrote Lee Mierow in a letter that was published online.

He praised the parent's patriotism but reminded them that "the Constitution guarantees the fundamental rights and civil liberties of every person in this country."

"The pledge is read and recited in Spanish by those students whose primary language is Spanish and is not recited by our English-speaking students who are not fluent in Spanish," he wrote.

The story caught the attention of U.S. English, a Washington, D.C.-based advocacy group that wants to make English the official language of the nation.

"Administrators in Wrightstown owe it to their students, especially those whom English is not their first language, to instill in them the value of speaking and understanding our common language," wrote CEO Mauro Mujica in a letter to the local newspaper. "That includes reciting the Pledge of Allegiance in English."

The concerned parent added, "The purpose of the Pledge of Allegiance is to inspire patriotism and unify American." And to recite it in Spanish, she said, is offensive."
