Sen. Marco Rubio on Wednesday reiterated his opposition to Donald Trump’s proposed ban on Muslims entering the U.S., by saying a ban wouldn’t have prevented the Orlando nightclub shooting conducted by a U.S. citizen.

“The killer was born in the same place Donald was: Queens,” the Florida Republican said. He was referring to Omar Mateen, who killed 49 people and injured 53 at Pulse, a gay nightclub in Orlando, early Sunday.
