NEW YORK (AP) — New York City's embattled public housing chief says she is leaving an agency that faces "real struggles."

Shola Olatoye (oh-LAH'-twoh-yay), who departs at the end of April, said Tuesday that she's taken pride in serving one in 14 New Yorkers.

She calls her announcement a "bittersweet moment."

Olatoye acknowledged residents' concerns about possible lead paint hazards and winter healing failures.

She says it "unnerves" her that the agency has "failed" in those areas.

The nation's largest public housing system has suffered years of neglect.

Politicians are simultaneously promising a fix and using the crisis to blame and bludgeon their rivals in an election year.
