New York City Mayor Bill de Blasio joined Megyn Kelly tonight to discuss his meeting with Donald Trump at Trump Tower.

De Blasio has often spoken out against the president-elect and his team's proposals, particularly the creation of a registry to track immigrants coming to the U.S. from Muslim countries.

"It's a problem because it doesn't conform with our American constitutional values and our respect for all religions," de Blasio said.

He argued that it's one thing to track potentially dangerous individuals, but it's quite another to treat people of a certain faith differently across the board.

De Blasio said that he voiced his concerns to Trump during their meeting today, which he called "constructive."

He explained that he wants Trump to come out and clearly state that American Muslims will be treated the same as their fellow citizens, and people who want to come to the U.S. will be judged individually and not on their faith.
