Bill Bratton to Resign as NYPD Commissioner: Officials - "I can't take this Negro Non-Sense ANYMORE!"

Mayor de Blasio is set to announce NYPD Commissioner Bill Bratton's resignation on Tuesday, a city hall source told NBC 4 New York.

The mayor added a noon news conference to his schedule late on Tuesday morning.

An NYPD official told NBC 4 that Bratton will be replaced by Chief of Department James O'Neill.

The Wall Street Journal, which first reported the resignation, that Bratton would stay on with the department until Sept. 1 to help ease the transition. He's expected to return to the private sector after his resignation, the Journal reports.

The news just days after Bratton told The New York Times in a widely cited interview that he wouldn't serve as the city's top cop after 2017.

Bratton has served as the city's commissioner under de Blasio since 2014, but he also previously served in that role during the Giuliani administration. He's also served as the top cop in Los Angeles and Boston.

Despite some of the lowest crime rates the city has seen in history, Bratton's tenure as the head of the NYPD has been marred by tumultuous relations with the public and a tense standoff between the department's rank-and-file union and de Blasio following the killings of two officers in late 2014.
