A Jewish head of an organization dedicated to combating hate crimes in the US has said that if the new administration of President-elect Donald Trump creates a national database for the religion’s followers, he will register as a Muslim.

“As Jews, we know what it means to be registered and tagged, held out as different from our fellow citizens,” Jonathan Greenblatt, Anti Defemation League (ADL) CEO, said on Thursday at the group’s Never Is Now conference on anti-Semitism in New York.
