NEWARK -- Conan O'Brien is now banned from the entire state of New Jersey. That's Newark Mayor Cory Booker's latest facetious response to the late-night comic's mockery.

The video posted today on YouTube is Booker's second public defense of New Jersey's largest city — butt of a "Tonight Show" joke last week. It comes after a two-minute segment Wednesday night by O'Brien, who pretended to laud Newark's virtues while showing images of urban neglect. A reference to its arts scene was accompanied by a graffiti-covered wall.

The exchange began last week with O'Brien joking that the city's new health care program consisted of a bus ticket out of Newark. Booker responded Tuesday with a YouTube video "banning" O'Brien from Newark Liberty International Airport.
