The Foundation for Moral Law, founded by Republican Senate candidate Roy Moore, said Tuesday it has sent letters to Alabama school superintendents outlining that student-led prayer at football games is permitted by the U.S. Constitution.

The foundation said it was responding to calls by the Freedom from Religion Foundation to at least Alabama high schools during the football season to end public prayer. The FFRF is a Wisconsin-based organization that describes itself as "committed to the cherished principle of separation of state and church."

The FFRF routinely sends letters to schools and other public entities to end the practice of public prayer.

Alabama high schools that have received letters from the FFRF during the football season include Smiths Station in Lee County, Hewitt-Trussville in Jefferson County and B.C. Rain in Mobile County.

Moore's wife, Kayla, is president of the Foundation for Moral Law.

"The courts have never issued a blanket prohibition on prayer at athletic events," she said in a statement. "Provided the prayers are student-initiated and student-led, they are protected by the free speech and free exercise clauses of the First Amendment."

The First Amendment to the U.S. Constitution states: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances."

The statement Tuesday from Moore's foundation is the second over the past two weeks.

Moore's foundation also released a six-page "Memorandum on Student Religious Speech at Athletic Events" along with its statement.

The memorandum cites a Senate report from the 1850s as well as a handful of court cases that Moore's foundation interpreted as allowing for student-led prayer at public school events. The memorandum also provides a "sample athletic event student message policy" for school to adopt.

"The Foundation for Moral Law presents this memorandum in a sincere effort to protect student pre-game speech, religious or otherwise, in a manner consistent with the United States Constitution and the Alabama Constitution as interpreted by the courts," the memorandum said in its conclusion.

The memorandum ends with the foundation's attorneys offering their services to school systems and provides a contact phone number.
