In a tweet on Friday, he said the idea came from a reporter.

Trump refused to rule out a database and special IDs for Muslims in an interview with Yahoo! on Thursday.

“Certain things will be done that we never thought would happen in this country in terms of information and learning about the enemy,” he said when asked if he would implement the programs.

After he was asked about the comment later that evening by an NBC News reporter, Trump said he would “certainly implement” a database to track Muslims in the U.S.

When asked whether Muslims would be legally required to sign up for the database, he said, “They have to be. They have to be.”

The GOP primary front-runner has been widely criticized for the controversial comments that come after the terrorist attack in Paris last week.

Fellow Republican presidential candidates Jeb Bush and Sen. Ted Cruz (R-Texas) have refused to back the plans.
