NEW YORK (AP) -- New York Mayor Bill de Blasio is winding down his first year in office, which saw success at fulfilling many of his liberal campaign promises.
But it at times has been overshadowed by events beyond his control, most notably the recent killings of two New York Police Department officers amid a wave of protests against police conduct.
De Blasio's backers point to his massive expansion of pre-school and other legislative accomplishments meant to improve the fortunes of those living at the margins of the nation's largest city.
But the year ends with his young mayoralty facing its biggest crisis yet: an open rebellion from police officers who don't believe the mayor supports them.
Experts warn that feud could hinder the rest of de Blasio's agenda.
