All this week on the Brian Lehrer Show we're checking in on the de Blasio administration's progress on a variety of key issues, six months into his first term. We'll talk to advocacy groups about how the mayor has lived up to his campaign promises on the environment, crime, housing, and more. Friday, we'll hear from Deputy Mayor Anthony Shorris.

Barika Williams, Policy Director at Association for Neighborhood and Housing Development (ANHD), assesses the Mayor's housing plan -- including increased density -- and how it compares to his progressive vision for the city. Plus, she'll review new policies on homelessness and neighborhood outreach.
