From the March 24 edition of Fox News‘ Fox & Friends:

STEVE DOOCY (HOST): In the wake of the Brussels attack, Ted Cruz and Donald Trump both agree that maybe there should be some patrolling of Muslim areas in the United States. Former New York City Mayor Rudy Giuliani used to survey and surveil the mosques here. So does it work?

RUDY GIULIANI: Well sure, I started that policy in 1994, because the bombing in 1993 of the World Trade Center was planned in a mosque in New Jersey.
