Several of New York City's top officials are joining Sen. Charles Schumer in criticizing a plan that would cut federal counterterrorism funding.

Mayor Bill de Blasio, Police Commissioner William Bratton, Fire Commissioner Daniel Nigro (NY'-groh) and others denounced the White House plan on Wednesday.

The proposal would cut funding to the Urban Area Security Initiative from $600 million to $330 million.

It would trim the funding for New York City from $180 million to $90 million. The money helps offset local municipalities' security expenditures.

Bratton called the plan "unconscionable" and said that the money was vital to keeping the city safe.

The White House had said the plan still contributes "robust funding" to combat terror.

Schumer said a vote on a Homeland Security appropriations bill would likely happen by June.
