New York City Mayor Bill de Blasio has been re-elected to a second term in office.

The incumbent mayor shook hands with voters Wednesday morning after he delivered his victory address from his campaign headquarters at the Brooklyn Museum Tuesday evening. His Republican challenger, state Assemblywoman Nicole Malliotakis, gave her concession speech from her Williamsburg, Brooklyn headquarters about 20 minutes before de Blasio took the stage.

De Blasio in his speech made mention of his 3-K for All program and talked about establishing trust and accountability for NYPD officers. He wants patrol officers to know the names of the people they serve and said all officers will wear body cameras.

He also touched on the so-called millionaires tax, which he says will help provide low-income residents with MetroCards and offset some city costs.

Five others -- Sal Albanese, Akeem Browder, Michael Tolkin, Bo Dietl and Aaron Commey -- were vying for the position but failed to have a significant impact on overall numbers.

De Blasio campaigned heavily on his efforts to increase affordable housing, especially for senior citizens, and address the city's high cost of living. He also touted lower crime rates and the rollout of universal pre-K.

Elsewhere in city races, Democrat Letitia James won re-election for New York City public advocate and Democrat Scott Stringer won re-election for city comptroller.
