The head of New York City's Hurricane Sandy reconstruction program has stepped down.
Kathryn Mallon is no longer in charge of "Build it Back."
The program provides money to city residents to help rebuild homes destroyed by Hurricane Sandy.
"We thank her for her service," de Blasio said. "We are looking at the entire dynamic of Sandy recovery. We obviously feel that we have to do a lot better going forward. So it's something we're going to be talking about publicly in the coming weeks, how we are assessing the state of play and what we intend to do to strengthen our efforts. I'm not, obviously, comfortable with the fact that so many people have not been able to get back in their homes."
Some critics say that the program has failed to distribute recovery funds to homeowners.
No replacement has been announced.
