Mayor Bloomberg is taking Washington to task for failing to fund a counter-terrorism program for cities.
Bloomberg says the Securing the Cities initiative is a worthy expense, because it goes toward detecting so-called "dirty bombs."
"The explosion of one nuclear device could cost thousands of lives, devastate our national economy, plunge us into further conflicts overseas," Bloomberg says. "We've just got to start taking this threat seriously."
He addressed a midtown meeting of the Homeland Security Advisory Council, hosted by Homeland Security Secretary Janet Napolitano.
Bloomberg also says the city needs more anti-terror funding because of its high risk of attack. Napolitano listened, but did not address the mayor's concerns, and did not take media questions afterward.
