Mayor de Blasio Says Homeless Problem is ‘Decades Old’

Yes, there is a homeless problem in New York City, Mayor Bill de Blasio acknowledged on Tuesday — even as he emphasized that his administration’s policies should not be blamed.

Mr. de Blasio, facing a public outcry over street homelessness, has taken pains of late to argue that he is on top of the problem, describing a slate of policies that he says will curb the crisis and announcing the resignation of the deputy mayor who had overseen City Hall’s homeless strategy.
