Moore made the call in a post on X on Wednesday while announcing the introduction of a proposed bill known as the CRUSADE Act.
According to the lawmaker, the legislation is aimed at blocking the promotion of religious practices he claims are incompatible with American constitutional principles.
He argued that Sharia law conflicts with core U.S. values, alleging that it permits the persecution of religious minorities, restricts women’s rights, and places religious authority above civil law.
“This is why I introduced the CRUSADE Act,” Moore said.
He further stated that immigrants arriving in the United States as religious workers should explicitly reject Sharia law and affirm their commitment to the Constitution.
Sharia law, which is based on Islamic religious teachings, is practised in different forms across several Muslim-majority countries and communities worldwide.
Meanwhile, former presidential candidate of the New Nigeria Peoples Party (NNPP), Rabiu Kwankwaso, has claimed that “indigenous enemies” within Nigeria were behind efforts to link him to a proposed U.S. bill targeting alleged religious freedom violations.
Naija News reports that U.S. lawmakers recently introduced the “Nigeria Religious Freedom and Accountability Act of 2026”, which proposes sanctions against Kwankwaso over alleged violations of religious freedom.
If passed, the bill could lead to visa bans and asset freezes against individuals and groups, including Kwankwaso and the Miyetti Allah Cattle Breeders Association (MACBAN), over alleged involvement in persecution claims.
Reacting during an interview on Arise Television’s ‘Prime Time’, Kwankwaso said he was surprised by the allegations, insisting he was being wrongly blamed for developments linked to Sharia law in Kano.
He said he was unfairly included in the submissions to the U.S. Congress and defended his past involvement in the introduction of Sharia law, noting that it followed due process and was widely accepted at the time.
