“The new administration plans to force Muslims to register on some master list,” Jonathan Greenblatt, CEO of the Anti-Defamation League (ADL), told listeners at the group's Never is Now Conference in New York Thursday, according to Haaretz. "As Jews we know what it means to be forced to register.

“I pledge to you that because I am committed to the fight against anti-Semitism that if one day Muslim-Americans are forced to register their identities, that is the day this proud Jew will register as Muslim. Making powerful enemies is the price one must pay, at times, for speaking truth to power.”

Trump supporters have floated a registry of Muslim immigrants as part of efforts to combat radical Islamic terrorism, but officials with his transition team have denied any such plans.

Greenblatt added Americans must reject all forms of discrimination regardless of which minority group it targets.

“No one has an excuse for excusing intolerance. We must stand with our fellow Americans who may be singled out for how they look, where they’re from, who they love or how they pray," he said

Kansas Secretary of State Kris Kobach (R), an immigration hard-liner who has been advising Trump, said Wednesday that transition policy advisers were debating the merits of such a database.

Trump’s communications director, however, denied Thursday that Trump supports monitoring individuals based on their faith.

“President-elect Trump has never advocated for any registry or system that tracks individuals based on their religion, and to imply otherwise is completely false,” Jason Miller said in a statement to CNN.
