(NewsNation) — More than 60 National Football League players have called on the U.S. to step in and halt persecution of their fellow Christians in Nigeria.

The letter was sent to President Donald Trump and House Speaker Mike Johnson, among others, according to Sports Spectrum.

Hall of Fame head coach Tony Dungy, Atlanta Falcons quarterback Kirk Cousins, New York Giants quarterback Jameis Winston, San Francisco 49ers quarterback Brock Purdy, Houston Texans quarterback C.J. Stroud and New England Patriots running back TreVeyon Henderson were among the signees.

“Religious and ethnic persecution in Nigeria has reached a level that demands immediate, concrete action from the United States,” the letter states.

“As current and former NFL players who care deeply about justice — here in America and around the world — we are grieved and outraged by the mounting violence, and we write to urge you to act now to confront religious persecution in Nigeria and ensure that those responsible are held to account.”

President Trump said Oct. 31 that “something must be done” as “Christianity is facing an existential threat” in the African nation. He wrote on Truth Social at the time that delegates would be looking into the matter and the U.S. was “ready, willing and able to save our Great Christian population around the world.”

The players expressed their gratitude for comments made by the likes of the president but are hoping for more drastic measures.

“We appreciate previous statements condemning violence and recognizing the suffering, but concern is no longer sufficient,” they said.

“As men who have been entrusted with a public platform through the National Football League, we feel a moral responsibility to speak for those whose cries have gone unanswered for far too long,” the letter ended.
